    BACKGROUND OF THE INVENTION
    [001] This invention generally relates to intravenous (IV) infusion devices, including IV catheters. In particular, the invention relates to an IV catheter assembly that has a blood control valve and an activator fixation that secures the IV catheter assembly and activates the blood control valve to, for example, enable withdrawal or assist in the insertion of secondary catheters and guidewires for longer-delay catheters.
    [002] IV catheters are commonly used for various infusion therapies, including infusing fluids into a patient, drawing blood from a patient, or monitoring various parameters of the patient's vascular system. IV catheters are also used as tools for introducing longer-delay catheters such as peripherally inserted central catheters (PICC). The initial catheter is placed in the vascular system and then secondary catheters or guidewires are introduced into the vascular system using the path created by placing the initial catheter. The initial catheter that was introduced as an insertion guide is then removed, leaving only the long-standing catheter in place.
    [003] The catheters are typically connected to a catheter adapter that accommodates the attachment of IV tubing to the catheter. Blood control catheter assemblies include an internal blood control valve that is tightened by inserting a male luer or other object at a proximal end of the catheter adapter. Therefore, following the placement of the catheter in a patient's vasculature, an IV fluid source can be connected to the catheter adapter, opening the blood control valve. Thus connected, the fluid from the IV source can begin to flow to a patient through the catheter.
    [004] Some catheter adapters allow verification of proper placement of the catheter in the blood vessel prior to the start of the blood infusion, providing a reflux chamber of the catheter assembly where a “reflux” of blood can be observed. To confirm reflux in catheter assemblies that do not include a blood control valve, a clinician must manually occlude the vein to prevent unwanted exposure to the blood. In contrast, blood control valves can eliminate the need for manual occlusion, while also reducing the likelihood of blood exposure during catheter placement.
    [005] Despite the many advantages of blood control catheters, some traditional procedures that involve vascular access systems or are hampered by blood control catheters are not possible. The devices and systems that overcome these deficiencies are described here. SUMMARY OF THE INVENTION
    [006] The present invention was developed in response to problems and needs in the technique that have not yet been entirely solved by the currently available systems. To overcome the limitations discussed here, the present invention provides an activator fixation that can be selectively attached to a blood control catheter set to open its internal blood control valve and allow open access to the catheter and / or the patient's vasculature. Once such access is available, blood collections can be performed and secondary catheters and guidewires for long-term catheters can be inserted through the activation of an activator. These processes are not advisable or possible within the fixation. For example, blood control catheters alone do not allow blood to flow through the proximal end of the catheter device. Therefore, blood sampling that is commonly done through proximal opening of the catheter is not available to clinicians. In addition, the process of inserting a guidewire through blood control catheters is complicated and not advisable because the guidewire can reach and possibly damage the septum or other features when the tip of the wire is inserted. Therefore, the fixation of an activator can enable traditional procedures that are not possible or are hampered with blood control catheters.
    [007] In one aspect of the invention, an activator attachment includes an activator attachment body, a probe member of the activator attachment body, and a cannula attached to the probe member. The activator fixation body has a distal end, a proximal end, and a lumen that extends through these activities. The lumen has an unrestricted proximal opening. The lumen extends through the probe member, which is molded and sized to be inserted into a proximal opening of a catheter adapter. The cannula has an extension that is greater than the combined extension of a septum activator and a septum disposed within the catheter adapter.
    [008] In another aspect of the invention, an activator attachment includes an activator attachment body and a probe member of the activator attachment body. The activator fixation body includes a distal end, a proximal end, and a lumen that extends between the distal and proximal ends. The lumen has an unrestricted proximal opening. The probe member has a lumen that extends through the probe member. The probe member is molded and dimensioned to be inserted into the proximal opening of a catheter adapter.
    [009] In another aspect of the invention, a catheter assembly system includes a catheter adapter and an activator fixation. The catheter adapter has an internal lumen that extends between the proximal opening of the catheter adapter and a distal end of the catheter adapter. A septum is disposed within and selectively seals the inner lumen. A septum activator is disposed within the internal lumen at a location proximal to the septum. The septum activator is configured to advance distally through a gap in the septum. The activator fixation has a distal end, a proximal end and an unrestricted lumen that extends between them. The distal end of the activator fixation has a probe member through which the lumen extends, the probe member having external dimensions configured to fit within the proximal opening of the catheter adapter.
    [010] In yet another aspect of the invention, an activator fixation includes an activator fixation body comprising a distal end, a proximal end, and a lumen extending between those ends. The lumen has an unrestricted proximal opening. A probe member of the activator fixation body has a lumen that extends into the activator fixation body. The probe member is adapted and sized to be inserted into a proximal opening of a catheter adapter. The probe member is long enough to contact a septum activator within the catheter adapter and advance the septum activator distally through the slot when the probe member is inserted into the proximal opening of the catheter adapter. An extension member extends distally from a distal end surface of the probe member. The extension member is shaped and sized to fit within a distal opening of an internal lumen of the septum activator. An interlocking aspect is arranged on an external surface of the extension member, the interlocking aspect of the extension member being configured to interlock with a male interlocking aspect of the septum activator.

    [032] Referring now to Figure 1, catheter assembly 10 and activator fixation 40 are illustrated. Catheter assembly 10 generally includes a catheter 12 coupled to a distal end 32 of a catheter adapter 14. The assembly catheter 10 can be referred to as a blood control catheter assembly when it includes a blood control valve in it. Catheter 12 and catheter adapter 14 are integrally coupled so that an internal lumen 16 of catheter adapter 14 is in fluid communication with a lumen 18 of catheter 12. Catheter 12 generally comprises a biocompatible material that has sufficient stiffness to withstand pressures associated with catheter insertion in a patient. A tip portion 20 of the catheter can generally be configured to include a beveled cut surface. The chamfered cutting surface can be used to provide an opening in a patient to allow insertion of catheter 12 into the patient's vascular system.
    [033] One skilled in the art will appreciate that aspects of the present invention can be incorporated for use with a needle-covering catheter assembly, which can include a catheter 12 with a tapered end instead of a cutting surface beveled. For example, one skilled in the art will appreciate that a flexible or semi-flexible polymer catheter can be used in combination with a rigid introducer needle to enable catheter insertion in a patient. One skilled in the art will also appreciate that surgically implanted catheters or other types of catheters can also be used.
    [034] Once inserted into a patient, catheter 12 and catheter adapter 14 provide a fluid conduit to facilitate the distribution of a fluid for and / or recovery of a patient's fluid, as required by a procedure. - desired infusion line. Thus, in some embodiments, the material of catheter 12 and catheter adapter 14 are selected to be compatible with biological fluids and drugs commonly used in infusion procedures. In addition, in some embodiments a part of catheter 12 and / or catheter adapter 14 is configured to be used in combination with an intravenous tube section to also facilitate the delivery of a fluid to or the removal of a fluid from a patient through an opening 26 at the proximal end 22 of the catheter adapter 14.
    [035] In some embodiments, a proximal end 22 of the catheter adapter 14 includes a flange 28. The flange 28 provides a positive surface that can be configured to connect to the intravenous tubing or an activator fixation 40 for the catheter assembly 10. In some embodiments, the flange 28 includes a set of threads 30. The threads 30 are generally supplied and configured to receive in a compatible manner a complementary set of threads 30 of a connector part 42 of the activator attachment 40. The threads 30 can be luer threads and form a luer hole. A connector portion 42 of the activator fixation 40 is generally coupled to the proximal end 22 of the catheter adapter 14 in an airtight manner. In some embodiments, an internal part of the actuator attachment 40 extends outwardly to provide a probe member 46.
    [036] In some embodiments, the proximal end 22 for the catheter adapter 14 includes a female luer connector that has a female luer cone and / or female luer lock threads. The female luer cone can be arranged at least in part within the proximal part of the inner surface 24 of the catheter adapter 14. Additionally, the aforementioned flange 28 and / or threads 30 may comprise the female luer lock threads. The female luer connector can therefore be configured to contact a male luer lock or male luer slip. Each of these components can be sized and configured in accordance with at least part of the International Standards Organization (ISO) standards for female and male luer connections under current or future standards. Therefore, the proximal end 22 of the catheter adapter 14 can therefore be configured to connect to a male luer lock or a male luer slip of an activator fixture 40, an IV line, luer access connector, needle hub, plug of ventilation, or other known or future developed IV device.
    [037] The probe member 46 of the activator fixation 40 can generally be configured to insert in a compatible manner into the opening 26 at the proximal end 22 of the catheter adapter 14. The probe member 46 can thus be shaped and sized to fit within. from the proximal end 22 of the catheter adapter 14. The probe member 46 can be tapered so that the probe member 46 can form an increasingly tight pressure fitting with the opening 26 and the lumen 16 of the catheter adapter 14 as probe member 46 is advanced further into the catheter adapter 14. Specifically, probe member 46 may include a male luer cone, as previously mentioned. As such, the activator fixation 40 is inserted in a compatible manner in the female luer within the proximal end 22 of the catheter adapter 14. As illustrated, probe member 46 may include an extension member 48 connected to a distal end surface 44 probe member 46. Extension member 48 can be inserted into the inside of a septum activator, as shown in Figures 4 and 5 and described with reference to those Figures.
    [038] Following the insertion of the probe member 46 in the opening 26, the connector part 42 of the activator fixation 40 can be rotated to interlock the connector part 42 and the flange 28 and / or the threads 30. In some embodiments, the connector part 42 forms a collar around the probe member 46, as shown in Figure 3. The collar can rest on the flange 28 of the catheter adapter 14 as the probe member 46 is inserted into the lumen 16 of the catheter adapter 14. Specifically, the collar can be a luer lock collar that includes the luer threads (not shown) or a luer slip collar that does not include any threads. The probe member 46 may extend outwardly at the end of the connector portion 42.
    [039] During the interconnection process of connector part 42 and flange 28, probe member 46 is advanced in lumen 16 of catheter adapter 14 to an inserted position, as shown in Figure 3. Probe 42 can be molded and dimensioned so that in the inserted position, the probe member 46 activates a blood control valve (not shown) inside the catheter assembly 10 to allow the flow of fluid through the catheter 12 and the catheter adapter 14.
    [040] Referring now to Figure 2, a cross-sectional view of an embodiment of a catheter set 10 is illustrated before activation of a septum 50 via a septum activator 80. Catheter set 10 includes a internal blood control valve that can be opened by inserting a male luer or other object into the proximal opening 26 of catheter adapter 14. Catheter assembly 10 may include a blood control valve, which usually includes less a septum 50 and a septum activator 80, which are arranged inside the internal lumen of the catheter adapter 14.
    [041] In some embodiments, the septum 50 is positioned inside the inner lumen 16 of the catheter adapter 14. The septum 50 generally comprises a flexible or semi-flexible polymer plume that has an outside diameter that is configured to to fit in a compatible manner within a groove or channel 60 formed on an internal surface 24 of the catheter adapter 14. In some embodiments, the septum 50 has a cylinder shape that has a barrier surface 52 comprising a distal end of the septum 50 and which also has an opening 54 which comprises a proximal end of the septum 50. When positioned within the channel 60, the barrier surface 52 of the septum 52 divides the inner lumen 16 of the catheter adapter 14 in a forward fluid chamber 62 and a chamber rear fluid 64. In this way, the presence of septum 50 can control and / or limit the flow of fluid between the front and rear fluid chambers 62 and 64. Specifically, a chosen configuration that of the barrier surface 52 of the septum 50 largely de-terminates the ability of a fluid to flow through the internal lumen 16 of the catheter adapter 14.
    [042] For example, in some embodiments the barrier surface 52 of the septum 50 is configured to enable a gap 56. The slot 56 is configured to provide selective access of a fluid flow through the barrier surface 52. In some modalities, the slot 56 is configured to remain in a closed and airtight position until it is activated or opened by advancing a septum activator 80 through the slot 56 in a distal direction 90. In some modalities, the surface of barrier 52 comprises a slit 56. In some modalities, the barrier surface 52 is modified to include multiple slits 56, such as two, three or more than three slits 56.
    [043] In some embodiments, catheter set 10 also includes an introducer needle (not shown) to assist a user in accessing the patient's vein during the catheterization process. Slit 56 allows the introducer needle to pass through the septum 50, thereby allowing a sharp tip of the introducer needle to extend distally beyond the tip part 20 of catheter 12. Following the catheterization procedure, the introducer needle can be removed from catheter assembly 10 and disposed of safely.
    [044] In some embodiments, the introducer needle is coated with a significant amount of silicone or similar fluid, such as fluorosilicone. The purpose of the coating fluid can be threefold. First, the coating fluid can act as a lubricant between the outer surface of the introducing needle and the interface surfaces of the slit 56. Thus, when removing the introducing needle from the septum 50, the coating fluid prevents adhesion between the outer surface of the introducer needle and the interface surfaces of the slit 56. Second, excess coating fluid builds up inside the slit 56 thereby helping to seal the septum 50 to prevent blood from flowing back through the septum following the removal of the introducer needle. Excess coating fluid accumulates within slot 56 as the introducer needle is removed from catheter assembly 10. Specifically, when the introducer needle is being withdrawn through septum 50, the interface surfaces of slot 56 act to clean the coating fluid from the outer surface of the introducing needle thereby displacing the coating fluid into the slot 56. Third, the coating fluid acts as a lubricant to prevent unwanted adhesion between the opposite surfaces of the slot 56.
    [045] The coating fluid can include any biocompatible lubricant. In some embodiments, the coating fluid comprises a lubricant such as a non-wetting lubricant that is applied at an interface between the introducing needle and the slot 56 to also eliminate possible leakage of the fluid and / or air. A non-wetting lubricant can also be beneficial in preventing tearing or other damage to the crack that can occur when the needle is removed from the catheter assembly following catheterization. A non-wetting lubricant can also facilitate proper realignment of the opposite surfaces of the slot 56 following removal of the introducing needle. Non-limiting examples of a non-wetting lubricant include known Teflon based on non-wetting materials such as Endura, from Endura Coating Co .: A20, E-20, 1000-S20, FEP Green, PTFE and X-40 from Tiodize; Cammie 200 from AE Yale; 21845 to Ladd Research; MS 122-22, MS 122DF, MS-143DF, MS-122VM, MS143V, MS-136W, MS-245W, U0316A2, U0316B2, MS-123, MS-125, MS-322 and MS-324 from Miller-Stepenson; and 633T2 by Otto Bock can also be used. Various materials other than Teflon based on the type of non-wetting lubricant include Dylyn, from ART, Nyebar, Diamonex, NiLAD, TIDLN, Kiss-Cote, Titanium Oxide; Fluorochemical coating Fluocad FC-722, 3M; Dupont Permacote; Plasma Tech 1633 from Plasma Tech, Inc .; and silicone sprays.
    [046] For some infusion therapy techniques, it may be desirable to allow a controlled flow of fluid through the septum 50 prior to the activation of the septum 50 with the activator 80. Thus, in some embodiments, the slit 56 also comprises a leakage port (not shown) positioned on the barrier surface 52. The leakage port can be an open hole that is sized to allow controlled flow of liquid or air between the front and rear chambers 62 and 64 In some embodiments, the barrier surface 52 is modified to include a single leak hole 58. In other embodiments, the barrier surface 52 is configured to include multiple leak holes. In other embodiments, the barrier surface 52 does not includes a slit 56, but instead includes at least one leak hole 58. For these embodiments, the septum 50 generally comprises an elastic material so that when the septum activator 80 is advanced in a distal direction 90, a conductive edge 92 of the septum activator 80 contacts the barrier surface 52 and stretches the orifice 58 to provide an opening that is large enough to allow for increased airflow and / or fluid through the septum 50.
    [047] The groove or channel 60 on which the septum is seated comprises a recessed portion of the inner surface 24 of the catheter adapter 14. The ex-suit diameter of the septum 50 is generally configured to fit in a compatible and secure manner within the channel 60 For example, in some embodiments, the ex-suit diameter of the septum 50 is selected to be either slightly smaller than the diameter of the channel 60 or slightly larger than the diameter of the inner lumen 16. As such, the septum 50 is retained channel 60 when using the catheter set 10.
    [048] For some infusion therapy techniques, air flow between the front and rear chambers 62 and 64 may be desirable. For example, for those modalities that comprise a septum 50 that has an airtight slot 56, the passage of air from the front chamber 62 to the rear chamber 64 is prevented by the septum 50 before the opening or activation of the septum 50 via the septum activator 80, as previously mentioned. Thus, when catheter 12 of catheter assembly 10 is inserted into a patient's vascular system, positive pressure is developed within the front chamber 62 thereby preventing a desired reflux of the patient's blood into the catheter adapter 14. A reflux observable is generally desirable to confirm the precise placement of the catheter tip 20 into the patient's vein. Thus, in some embodiments of the present invention they include aspects or elements to enable airflow between the front chamber 62 and the rear chamber 64, without requiring activation of the septum 50 with the septum activator 80. As such, some embodiments of the present invention provide observable reflux, as generally desired for infusion procedures.
    [049] For example, in some embodiments, the barrier surface 52 of the septum 50 is modified to include the leak orifice 58, as previously mentioned. In other embodiments, a plurality of air ventilation channels 70 is interposed between the septum 50 and the inner surface 24 of the catheter adapter 14. The air ventilation channels 70 relieve positive pressure within the front chamber 62 by providing access to that the air diverts from the septum 50 to the rear chamber 64. In some embodiments, the air ventilation channels 70 are constructed by removing parts of the channel surface 60, resulting in a plurality of generally parallel grooves.
    [050] In addition to allowing air flow between the front and rear chambers 62 and 64, ventilation channels 70 can be configured to allow fluid to flow through catheter adapter 14 before activation or opening of slit 56 with the catheter adapter 80. In some embodiments, the rate at which air and / or fluid flows between chambers a greater or lesser number of ventilation channels 70. In some embodiments, the rate at which air and / or fluid flows between the front and rear chambers 62 and 64 are adjusted by the manufacture of the catheter adapter 14 to include the ventilation channels 70 provided with a larger or smaller cross-sectional area. Thus, in some embodiments, the rate at which air and / or fluid flows between the front and rear chambers 62 and 64 increases by the manufacture of catheter adapter 14 having either an increased number of ventilation channels 70, or ventilation channels 70 that have a larger cross-sectional area. Conversely, in some embodiments, the rate at which air and / or fluid flows between the front and rear chambers 62 and 64 is reduced by the manufacture of a catheter adapter 14 that has or a smaller number of ventilation channels 70 or ventilation channels 70 that have a smaller cross-sectional area.
    [051] With reference to Figure 2, as mentioned, the blood control valve includes a septum activator 80 that can activate septum 50. The septum activator 80 can comprise a probe-like structure that is mainly housed in the chamber back 64 of the catheter adapter 14. The septum activator 80 generally comprises a tubular body 82 having a distal end 84 and a proximal end 86. The tubular body 82 comprises a rigid or semi-rigid material, such as a plastic or metallic. The rear chamber 82 also comprises an internal lumen 88 to facilitate the flow of a fluid and / or liquid through the septum activator 80.
    [052] The distal end 84 of the tubular body 82 is configured to insert into the opening 54 of the septum 50. The distal end also includes a probing surface 90 that extends through the opening 54 of the septum 50 to a position proximal to the surface. barrier 52 of septum 50, as above. The upper surface 90 is advanced through the slot 56, or through the leakage port as the septum activator 80 is advanced through the catheter adapter 14 in a distal direction 90. The advance of the septum activator 80 through the catheter adapter 14 will be commented in detail below, in relation to Figure 3.
    [053] In some modalities of the septum activator 89, the distal end 84 of the tubular body 82 comprises a first diameter that is smaller than a second diameter of the proximal end 86. The narrower distal end 84 is configured to insert into the septum slit 56, while the widest proximal end 86 is configured to sit compatibly within the back chamber 64 of catheter adapter 14. In some fashion, septum activator 80 also includes a tapered intermediate section connecting the distal 84 and proximal 86 ends. All catheter adapter 80 can comprise a single piece, unitary structure.
    [054] In some embodiments, the proximal end 86 of the septum activator 80 also includes a retaining spring 110. The retaining spring 110 generally comprises a polarized portion out of the tubular body 82 configured to engage a retaining groove in a compatible manner. 68 of the catheter adapter 14, as shown in Figures 2. The interaction between the retaining spring 110 and the groove 68 can limit the lateral movement of the septum activator 80 within the lumen 16 of the catheter adapter 14. Thus, the width the retention groove 68 determines or limits the travel distance to the septum activator 80 inside the catheter adapter 14. Additionally, interactions between the retention spring 110 and the groove 68 can prevent removal of the septum activator 80 from the adapter of catheter 14. In some embodiments, the septum activator 80 comprises a plurality of retaining springs 110, while in other embodiments the septum activator 80 comprises only a single retaining spring. the 110.
    [055] In some embodiments, the septum activator 80 also comprises aspects to direct or divert fluid flow around and / or through the septum activator 80. Flow deviation can be important to prevent fluid stagnation or coagulation within dead zones within the septum activator 80 and / or the lumen 16 of the catheter adapter 14. Additionally, the stagnation of fluid flow through the catheter assembly 10 may result in the accumulation of undesirable drug concentrations within the catheter adapter. catheter 14 and / or septum activator 80. High undesirable concentrations can result in ineffective treatment causing serious side effects, including death. Thus, in some embodiments the septum activator 80 is modified to include flow deflectors 120 and flow deflection channels 130 to provide a leveling catheter assembly system 10.
    [056] Flow diverters 120 can generally comprise parts angled internally or externally from the outer surface of septum activator 80. Flow diverters 120 can be positioned to project into a flow path through catheter adapter 14. Thus , as the flow contacts flow diverters 120 the fluid flow path is agitated. Agitation results in the redirection of fluid flow, both through the internal lumen 88 of the septum activator 80, and between the outer surface of the septum activator 80 on the inner surface 24 of the catheter adapter 14. In some embodiments, the retaining spring 110 also serves as a flow diverter 120.
    [057] A flow bypass channel 130 can be provided to allow fluid exchange between the lumen of the catheter adapter 16 and the internal lumen 88 of the septum activator 80. Thus, the flow bypass channel 130 prevents the stagnation and / or fluid coagulation between the inner surface 24 of the catheter adapter 14 and the outer surface of the septum activator 80. In some embodiments, the flow bypass channel 130 comprises a window or opening in the surface of the tubular body 82. In other embodiments, the flow diversion channel 130 also comprises a flared or angled surface to also direct the fluid to flow through channel 130.
    [058] The proximal end 86 of the septum activator 80 also includes a contact surface 140. The contact surface 140 comprises the most proximal extremality portion of the septum activator 80 and is positioned inside the rear chamber 64 of the adapter. catheter 14 adjacent to the proximal opening 26 of catheter adapter 14.
    [059] As shown in Figure 2, prior to activation, septum activator 80 is fully positioned within the rear fluid layer 64 of catheter adapter 14. Additionally, retaining springs 110 are engaged within retaining groove 68 and positioned near the proximal end of the retention groove 68. A contact surface 140 at the proximal end 86 of the septum activator 80 is positioned close to the opening 26 of the catheter adapter 14. In some embodiments, a proximal opening 142 of the septum activator septum 80 can be in a plane generally parallel to the opening plane of the catheter adapter 26. Finally, the outwardly polarized retaining springs 110 can attach to the surface of the groove 68 thereby maintaining the inactive position of the septum activator 80 within of the catheter adapter 14.
    [060] Referring now to Figure 3, a cross-sectional view of the catheter set 10 is illustrated that follows the activation of the septum 50 via the septum activator 80. As described above, in some cases, it may be desirable to activate the septum 50 to allow flow to flow through it during certain medical procedures. For example, it may be desirable to activate septum 50 via an activator fixation 40 to introduce a guidewire into the catheter adapter 14. It may also be desirable to activate septum 50 using activator fixation 40 to perform a blood collection. through the proximal opening 26 of the catheter adapter 14.
    [061] Therefore, when inserting the activator fixation 40 into the proximal opening 26 of the catheter adapter 14, the probe part 46 of the activator fixation 40 contacts the contact surface 140 of the septum activator 80. The septum activator 80 is advanced in a distal direction 90 while the activator fixation 40 is also inserted into the proximal opening 26 of the catheter adapter 14. As the activator fixation 40 is also advanced in the proximal opening 26, the probing surface 90 of the activator septum 80 passes through the slot 56 in the barrier surface 52 of the septum 50. As such, the probing surface 90 of the septum activator 80 enters the front chamber 62 providing a fluid path through the septum 50. Using this open path of fluid, a clinician can perform a blood collection or insert a guidewire. It should be understood that activator fixation 40 can be used for other procedures besides performing blood collections and insertion type wires.
    [062] In some embodiments, the catheter set 10 is configured to allow the septum activator 80 to return to a position entirely inside the rear chamber 64 following the removal of the activator fixation 40 from the catheter adapter 14. Thus, when the activator fixation 40 is removed or detached from the catheter assembly 10, the fluid path through the septum 50 is closed again. In some embodiments, the retention spring 110 is configured to flex inwardly when contacting between the contact surface 140 of the septum activator 80 and the probe member 46 of the activator fixation 40. When the retention spring 110 flexes to inside, the upper surface 90 of the septum activator 80 is temporarily advanced in a distal direction 90 to polarize the opening of the slits 56, or the leak hole 58. When contact between WHO 46 and contact surface 140 ceases , the retaining spring 110 returns to its relaxed position. The relaxed position removes the upper surface 90 of the septum activator 90 from the barrier surface 52, thereby allowing slits 66 and 56 to close.
    [063] Reference will now be made to Figures 4 and 5, which illustrate an example of an activator fixation 40, according to some modalities. Figure 4 specifically illustrates an activator fixation 40 fixed to the catheter assembly 10 which has a valve blood control. Figure 5 illustrates an isolated view of the activator fixation 40 in Figure 4.
    [064] As illustrated, the activator fixation 40 can generally include a distal end, a proximal end, and a lumen 152 that extends between these ends. The body of the activator attachment 40 can be an integral and unitary body that can be formed as a single piece. The lumen 152 may have an unrestricted proximal lumen opening 160 through which a clinician can take a blood collection and / or introduce an object into the catheter assembly 10, such as a guidewire. The unrestricted opening can be a direct opening to the lumen 154 of the activator fixation, in which no object is present and which provides ir-restricted access to the lumen 154. In addition, the lumen 152 can be unrestricted, so that it forms a unobstructed direct path from the proximal lumen opening 160 to a distal lumen opening at the distal end of the activator fixation 40.
    [065] The body of the activator fixation 40 may include a probe member 46 that extends outwardly. Probe member 46 can be configured to activate ventilation channels when it is attached to the proximal end 16 of catheter adapter 14. When activator attachment 40 activates the blood control valve, a flow path is opened between the environment outer and the fluid front chamber 62 of the catheter adapter 14. The fluid path extends from a proximal lumen opening 160 to a distal lumen opening 162 of the activator fixation 40. The fluid path allows the clinicians access the fluid front chamber 62, catheter 12 and a patient's vasculature through the proximal lumen opening 160 of the activator fixation 40. Thus fixed, blood collection can be performed through the fixation of activator 40, and secondary catheters and guidewires for long-term catheters can be inserted through the fixation of an activator 40.
    [066] As shown in Figure 4, the probe part 48 of the actuator attachment 40 can be long enough to contact the contact surface 140 of the septum activator 82 to advance the septum activator 80 through the septum 50. The distal tremity of probe member 42 may include an extension member 48 that is shaped and sized to enter the proximal opening 142 (shown in Figures 2 and 3) of septum activator 80 when activator fixation 40 is inserted into the proximal opening 26 of catheter adapter 14. As illustrated, probe member 42 may have a distal end surface 44 that is configured to contact the septum activator contact surface 140 to advance septum activator 80. The limb Extension 48 can extend away from the distal end surface 44 of probe member 48. Extension member 48 has external dimensions that approximate the internal dimensions of distal opening 155 of septum activator 80. Therefore For example, an outside diameter of the strain member 48 may approximate or be less than the inside diameter of the distal opening 155 of the septum activator 80.
    [067] Extension member 48 can provide various functions for attaching activator 40. For example, extension member 48 can direct a guidewire towards septum 50. As illustrated, extension member 48 can also be molded and sized to cover at least part of one or more openings 130 within the septum activator 80 to prevent fluid or guidewire from entering these openings 130. Extension member 48 can also align probe member 46 against the contact surface 140 of the septum activator 80 when it is inserted into the catheter adapter 14. In some embodiments, the external dimensions of the extension member 48 are configured to approximate the dimensions of the inside of the septum activator 80 to prevent the flow of fluid out of the proximal lumen opening 142 of the septum activator 80 and / or through the flow bypass channels 130 in the septum activator 80.
    [068] In some embodiments, the activator fixation 40 can be inserted, but not attached to, into the catheter adapter 14. In these embodiments, the activator fixation 40 can be pressed to fit inside the catheter adapter 14. In other embodiments , such as those illustrated in Figures 4 and 5, the activator fixture 40 is connected to the catheter adapter 14. The activator fixture 40 can be connected to the catheter adapter 14 using various connection means including the snap fit connection, a screw connection, a coupling, a snap connection, and other suitable connections. As mentioned, in a specific embodiment, this connection can be between the male luer connector of the activator fixture 40 and the female luer connector of the catheter adapter 14. For example, as illustrated, the activator fixation 40 can connect to the catheter adapter 14 via one or more sets of male luer threads 156 which are configured to receive in a compatible manner and couple to a complementary set of female luer threads 30 of the catheter adapter 14. To facilitate the formation of a secure connection the activator clamping body 150 may include tightening aspects 158 such as ribs, a textured surface, or other suitable tightening aspects.
    [069] As also shown in Figure 4, the proximal lumen opening 160 of the activator attachment 144 may be larger than the distal lumen opening 162.The larger proximal lumen opening 160 can facilitate the insertion of a guidewire or another device. Therefore, in various embodiments, the inner lumen 152 may taper inward between the proximal lumen opening 160 and the distal lumen opening 162. In some embodiments, the proximal part of the lumen 152 includes a female luer cone 164.
    [070] In some embodiments, as illustrated in Figure 4, the activator fixation 40 can optionally include a channel part 157 shaped proximal to the activator fixation 40, and which is proximal to the connector part 42. The channel 157 can be directly connected to probe member 46 in a way that lumen 152 of the channel part connects directly to lumen 152 extending through probe part 46. channel part 157 can form an extended part of the activator attachment 40 through which the lumen 152 extends. The lumen part 152 within the channel part 157 may have a wider cross section (taken in a plane perpendicular to the longitudinal geometric axis of the lumen 152) than the lumen disposed within the probe member 46. As such, the medical team it may have a larger target area into which objects can be inserted into the proximal lumen opening 160 and from which blood can be recovered through that opening.
    [071] As will be understood, the fixation of activator 40 can have various shapes and sizes. In some embodiments, the extent of the activator fixation 40 extending between the proximal and distal ends may increase or decrease depending on the desired size, the size of the proximal lumen opening 160, and / or the intended use. In some embodiments, as shown in Figure 6, the activator fixture 40 does not include a tightening aspect 158 nor does it extend proximally beyond the connector portion 42 of the activator fixation 40.
    [072] Figure 6 illustrates an example of an activator fixation 40 that does not include channel part 157. Instead, activator fixation 40 ends at a proximal end of probe member 46. Here, lumen 152 can open to proximal lumen opening 160. In some embodiments, the actuator attachment 40 includes only a probe member 46 which is connected to a catheter adapter 14 via a connector part 42. The probe member 46 it can be a male luer, and the connector part 42 can be a male luer lock collar 42 that has male luer threads 156. In addition, as shown, the activator fixation 40 can include an extension member 48.
    [073] Reference will now be made to Figures 7A to 7E, which illustrate the use of an activator fixation 40 that has one or more interlocking aspects 170 on extension member 48. One or more interlocking aspects 170 can be used to interlock extension member 48 with septum activator 80. By using interlocking extension member 48 with septum activator 80, extension member 48 may be able to push septum activator 80 out of septum 50 to close the blood control valve after activator fixation 40 is performed. The septum activator 80 can be pulled back by activator fixation 40 through the interlocking aspects 170, which is connected to the septum activator 80. Thus, when the activator fixation 40 is disconnected from the catheter adapter 14, the blood control valve can be automatically closed.
    [074] As shown in Figure 7A, the attachment of activator 40 can include a plurality of interlocking aspects 170 on an external surface of extension member 48. For example, one, two, three, four, five, six, or more of six interlocking aspects 170 can be arranged on the external surface of the extension member 48. Each interlocking aspect 170 can be a protruding projection from the external surface of the extension member 48. As illustrated, some aspects interlock 170 may be a substantially triangular shaped protrusion. For example, an interlocking aspect 170 may include two inclined surfaces 172, 174 that can combine to form a triangular shaped protrusion. At least part of the interlocking aspect 170 can be inserted into an interlocking fitting aspect of the septum activator 80 when the activator fixation 40 is attached to the catheter adapter 14. As illustrated, the interlocking fitting aspect may include a hole or depression within the internal lumen 88 of the septum activator. Examples of a bore include flow diversion channels 130 in the septum activator 80. In some embodiments, the interlocking aspect 170 may be a de-pressure on the outer surface of the extension member 48, and the interlocking fit aspect of the septum activator 80 can be a protrusion within the internal lumen 88 that interconnects with the depression.
    [075] Specific references to the operations illustrated in Figures 7A to 7E will now be made. As shown in Figure 7A, the activator fixation 40 can be positioned close to the catheter adapter 14, with the probe member 46 and the extension member 48 positioned near the distal opening 26 of the catheter adapter 14. When the extension member 48 is advanced to lumen 88 of the septum activator 80, the distal inclined surfaces 174 of the interlocking aspects 170 can accommodate gradual entry of the extension member 48 into lumen 88. The inclination of the distal inclination surface 174 and the overall height of the interlocking aspect 170 can be configured so that the force required to insert the extension member 48 with the interlocking aspects 170 in lumen 88 is less than the force required to advance the septum activator 80 through septum 50. As such, the act of inserting extension member 48 into lumen 88 may not advance septum activator 80 through septum 50.
    [076] As illustrated in Figure 7B, when the activator fixation 40 is attached to the catheter adapter 14, the probe member 46 and the extension member 48 are inserted into the distal opening 26 of the catheter adapter 14. When the extension member 48 enters the internal lumen 88 of the septum activator 80, the interlocking aspects 170 can interlock with the interlocking interlocking aspects. For example, as illustrated, triangular-shaped protrusions are inserted into flow diversion channels 130 to intercommunicate probe member 46 with septum activator 80. At that point, activator fixation 40 can be fully advanced or connected over the catheter adapter 14. Alternatively, at this point, the fixation of activator 40 may not be fully advanced or connected to the catheter adapter 14. For example, at that point the fixation of activator 40 may have been advanced for the catheter adapter 14 to the point at which the male luer connection of connector part 42 of the activator fixation 40 contacts the female luer connection (which may include flange 28 and threads 30) of catheter adapter 14. Additional distal advance may be possible by threading or adjusting by pressing the connector part 42 on the catheter adapter 14.
    [077] As shown in Figure 7C, when activator fixation 40 is advanced further over catheter adapter 14, probe member 46 of activator fixation 40 pushes the contact surface 140 of septum activator 80, advanced septum activator 80 through septum 50. This section can open a fluid channel through the fixation of activator 40 to the distal fluid chamber 62 of catheter adapter 14. Continuing the previous example, this distal movement of the activator fixation 40 can be made at least in part when the male luer connection of the connector part 42 is connected to the female luer connection of the catheter adapter 14. This connection may involve a sliding connection or a threaded connection, in which the male luer connection is screwed onto the female luer connection.
    [078] As shown in Figure 7D, the activator fixation 40 can be removed when it is removed back through the septum 50 in a proximal direction 180 as the activator fixation 40 is removed. When the activator fixation 40 is removed, the proximal tilt surface 172 of the interlocking aspects 170 may contact a surface 176 of the interlocking fabrication aspect (e.g., flow bypass channels 130 to move the septum activator. 80 in the proximal direction 180). As such, fixation of activator 40 can pull septum activator 80 out of septum 50 towards septum 50. Therefore, in some embodiments, the inclination or other characteristics of the proximal tilt surface 172 and the overall height of the interlocking aspect 170 can be configured such that the force required to withdraw extension member 48 with interlocking aspects 170 out of lumen 88 of septum activator 80 is greater than the force required to remove septum 80 from within septum 50. As such, the initial movement of the activator fixation 40 in the proximal direction 180 does not remove the extension member 48 from lumen 88 of the septum activator 80.
    [079] As also illustrated in Figure 7D, the inner surface 24 of the catheter adapter 14 can include a retaining member 182, such as the annular projection shown. Retaining member 182 can assist in retaining septum activator 80 within lumen 16 of catheter adapter 14 and limiting the proximal movement of septum activator 80 beyond a certain point. In addition, as illustrated, the septum activator 80 may include a retaining aspect 184 that otherwise grabs or contacts the retaining member 182 to prevent any further proximal movement of the septum activator 80. In some embodiments, the limb retention is a depression formed within the inner surface 24 of catheter adapter 14. For example, as previously described with reference to Figure 2, catheter adapter 14 may include a retention groove 64 that limits the lateral movement of the activator septum 80. Similarly, as previously described, the retention aspect 184 of the septum activator 80 can be a retention spring 110, also as described with reference to Figure 2. Additionally, other types of retention members are contemplated in the aspects retainer 184.
    [080] Retaining member 182 and / or retaining aspect 184 may stop the proximal movement of septum activator 80 at a given point. The point can be at a location where septum activator 80 is removed entirely from septum 50. When septum activator 80 is removed from septum 52 at that point, the septum can return to its closed position by closing the blood.
    [081] As shown in Figure 7E, the activator fixation 40 is removed far in the proximal direction 180 at which point it disconnects from the catheter adapter 14 and the septum activator 80. In some embodiments, this includes unscrewing the luer connector male of the activator fixation 40 of the female luer connector of the catheter adapter 14.
    [082] In some modalities, during the removal of the activator fixation, the force applied in the activator fixation 40 can overcome the force required to remove the extension member 48 and block the interconnection aspects 170 outside the lumen 88 of the septum activator 80. In addition, the proximal tilt surface 172 can be configured so that the force required to pull extension member 48 out of lumen 88 of septum activator 80 is less than the force required to physically rupture either the extension member 48 or the septum activator 80. As such, after the septum activator 80 is stopped by the retention member and / or retention aspect 184, additional force in activator fixation 40 will lead to fixation of activator 42 to be released from septum activator 80. Additionally, the force required to release the fixation of activator 40 from septum activator 80 may be such that it can be done by a single user using a single hand and with only an amount of reasonable minimum strength.
    [083] Figure 8 illustrates another example of an extension member 48 configured to interlock with a septum activator 80. As illustrated, the external dimensions of the outer surface 190 of extension member 48 can be configured form a friction block with the inner surface 192 of the inner lumen 88 of the septum activator 80. The outer dimensions of the outer surface 190 and the inner dimensions of the inner surface 192 of the inner lumen 88 of the septum activator 80 can be configured accordingly. Thus, the force required to insert extension member 48 into the inner lumen 88, advance the septum activator, remove the septum activator, and remove extension member 48 from the inner lumen 88 is approximately the same with respect to the forces described with reference to Figures 7A to 7E.
    [084] Reference will now be made to Figures 9A and 9B, which illustrate another example of an activator fixation 40 according to some modalities. As shown in Figure 9A, activator fixation 40 can include a cannula 200 that is connected to probe member 46. Activator fixation 40 and cannula 200 can be configured so that when activator fixation 40 is connected -to a catheter adapter 14, the probe member 46 of the activator fixation 40 does not advance the septum activator 80. Additionally, the activator fixation 40 and the cannula 200 can be configured so that the cannula 200 can extend through the internal lumen 88 of the septum activator 80 and through the septum 50, opening the septum 50. Thus configured, the activator fixation 40 can bypass the septum activator 80 and open a fluid path between the fluid chamber distal 62 of the catheter adapter 14 and the internal lumen 152 of the activator fixation 40.
    [085] Referring to Figure 9B, in some embodiments, the inner lumen 206 of the cannula 200 can communicate with the inner lumen 152 of the activator attachment body so that fluid can flow through the cannula 200 into the lumen 152 of the activator fixing body. The cannula 200 can be longer than the combined length of the septum activator 80 and the bar surface 52 of the septum 50. Thus, the cannula 200 can have an extension configured to extend through the septum activator 80 and through septum 50 when probe member 46 is inserted into proximal opening 26 (as shown in Figure 9A) of catheter adapter 14. In addition, cannula 200 may have an outer diameter 204 smaller than the smallest inner diameter of an inner lumen 88 of the septum activator 80 so that the cannula 200 can be inserted through the inner lumen 88 of the septum activator 80. In some embodiments this outer diameter 204 is constant over the entire length of the cannula 200. In other embodiments, that outer diameter 204 is constant over a portion of the cannula extension 200. That portion may include the portion of the cannula 200 that extends through the part of the septum activator 80 that includes the smallest inner diameter or other int dimensions ernas. In addition, the cannula 200 may include a blind distal end 202 so as not to damage the flexible septum 50.
    [086] As also illustrated in Figure 9B, probe member 46 may have an extension that is not long enough to contact the contact surface 140 of septum activator 80 when probe member 46 is inserted into the adapter. catheter holder 14. For example, as illustrated, the connector part 42 may extend further than the probe member 46, which is thereby a blind probe member or a blind male luer. As such, probe member 40 cannot advance septum activator 80. Instead, septum activator 80 remains in place, while cannula 200 extends through septum activator 80 and the septum.
    [087] In light of the above, it will be understood that fixing activator 40 can provide several benefits. For example, activator attachment 40 can activate the blood control valve by pushing septum activator 80 through septum 50 thereby creating an open flow path. At that point, blood is allowed to leak through the septum, which can be useful for collecting and sampling blood. Attachment of activator 40 can also create a direct path for the guidewire to be inserted into the septum 50 in the vein, bypassing the large holes, while being guided to the center of the entire catheter set 10 and can be more easily inserted into the vein , during an MST procedure. Additionally, in some embodiments, the activator fixation 40 can help to automatically close the blood control valve after the activator fixation has ended.
    [088] The present invention can be incorporated in other specific forms without departing from its structures, methods or other essential characteristics as widely described and claimed hereinafter. The described modalities should be considered in all aspects only as illustrative, and not restrictive. Therefore, the scope of the invention is indicated by the appended claims, and not by the preceding description. All changes that affect the meaning and variation of equivalence of the claims must be covered within its scope.
