    Background of the Invention
    [001] The present invention relates to gate valves used in catheter sets. In medicine, catheter sets are used to properly position the patient's vascular system. Once installed, catheters, for example, intravenous (or "IV") catheters can be used to infuse fluids, which include normal saline solutions, medicinal compounds, and/or nutritional compositions, into the patient in need of this type of treatment. In addition, catheters make it possible to remove fluid from the circulatory system and monitor conditions within the patient's vascular system.
    [002] A commonly used type of catheter is a peripheral intravenous catheter. Such short, intravenous indwelling catheters are often used to provide an access route for medication, hydration fluid, and in some cases, for parenteral feeding of the patient. Generally speaking, the length of these catheters is short, ranging in length from about half an inch to three inches (12.7 mm to 76.2 mm), and they are generally made of flexible biocompatible materials. Peripheral intravenous catheters are often delivered as “over a needle” catheters fitted to an introducer needle with a sharpened distal end. A portion of the catheter, which includes at least its distal end, securely grips the outside of the needle to prevent the catheter from detaching during its introduction into the patient's circulatory system. Although several methodologies for the positioning of such catheters are practiced in the technique, in general, several of them include the step of inserting at least part of the needle into the intended vessel and then sliding the catheter over the needle to the location .
    [003] Confirmed the placement of the needle, the medical professional can remove the needle, leaving the catheter in place. A septum inside the catheter adapter can prevent fluid leakage during and after removal of the introducer needle. In general, septal structures are elastomeric and are designed to fully conform to the shape of the needle during storage and use to prevent leakage and, after removal of the needle, to provide a seal. However, if the needle remains in the septum for prolonged periods, it is possible that the septum will not be completely sealed after the needle is removed, having adapted, in part, to the shape of the removed needle. An incompletely sealed septum may increase the medical professional's risk of exposure to blood, as blood may flow through the small opening in the septum cleft. Therefore, a set of catheters with more reliable hermetic functionality would improve the technique. Such a catheter assembly is disclosed in this document. Invention Summary
    [004] The present invention was developed in response to the problems and needs in the art that to date have not been completely solved by the catheter sets available today. Therefore, these catheter assemblies were developed with the inclusion of a valve located in a port of a catheter adapter. Positioning the valve in the port allows you to avoid the problems involved when a valve is in the course of an introducer needle. This valve may also provide capability for infusing and extracting fluid through the port.
    Thus, in some aspects of the invention, a catheter assembly is provided that includes a catheter adapter having an internal lumen. A port on the catheter adapter can form an opening in the inner lumen. A valve can be attached to the door and selectively seal the opening of the door. The catheter assembly may also have a catheter tube and a septum within the inner lumen that seals the proximal end of the inner lumen.
    [006] Various types of valves that can be incorporated into the port enable the medical professional to infuse and extract fluids through the port. Non-limiting examples of valves include elastomeric septum, ball valve, and diaphragm valve. The valve can be a one-way valve or a two-way valve. The valve may be located on a removable luer access connector that can be connected and disconnected from the port. Alternatively, the valve can be located on a luer access connector that is fixedly connected to the port. The valve may be a luer access valve that accommodates the insertion of a luer device, such as those commonly used in the medical industry. In addition, a portion of the port body may include luer threads capable of securing the luer device to the catheter adapter. In some configurations, the port may be disposed at an angle to the longitudinal axis of the catheter to change the direction in which fluids are infused into the inner lumen. This angle can vary between about 15° and 90°.
    [007] Additionally, the valve in a port can confer numerous benefits when used in association with catheter sets with blood control. Blood Control Catheter Assemblies may have an internal blood control valve capable of remaining permanently open after being activated by the introduction of a luer. In these examples, the valve allows the medical professional to have an additional connection point that poses a limited risk of blood exposure. Thus, in some embodiments of the invention, the valve in the port is used in conjunction with a catheter assembly equipped with an internal blood control valve. The blood control valve may include a blood control septum located within the inner lumen of the catheter adapter. The septum activator may also be located within the inner lumen behind the blood control septum. When the separate luer device is inserted into the proximal end of the catheter adapter, the septum activator is advanced through the blood control septum, activating the latter.
    [008] In some aspects of the invention, a button that extends outwardly from a side wall of the catheter adapter can activate and deactivate the blood control septum. The button can be connected to the septum activator and be configured to move the septum activator distally through the septum when the button is pressed. In some embodiments, the button is configured to be pushed internally toward the inner lumen, and a translation mechanism translates the button's internal movement into a distal movement of the septum activator.

    [021] The currently preferred embodiments of the present invention can be understood in reference to the drawings, in which like reference numbers indicate similar or functionally similar elements. It can be immediately seen that the components of the present invention, in the general way they are described and illustrated in the figures, could be arranged and designed in several different configurations. Therefore, the more detailed description below, as represented in the figures, is not intended to limit the scope of the invention as claimed, but is merely representative of currently preferred embodiments of the invention.

    [024] Figure 1 illustrates a cross-sectional view of one embodiment of a catheter assembly 10. As shown, catheter assembly 10 generally includes a catheter 12 coupled to the distal end 26 of a catheter adapter 14. Catheter 12 and catheter adapter 14 are integrally coupled so that inner lumen 16 of catheter adapter 14 extends within catheter 12. Catheter 12 generally includes a biocompatible material made of flexible or semi-flexible polymer. Catheter 12 can be used in combination with a rigid introducer needle 20, as shown, to allow the introduction of catheter 12 into the patient. It is understood that other types of implantable catheter assemblies can also be used in combination with the present invention.
    [025] After the introducer needle 20 is removed from the catheter 12 and the catheter adapter 14, fluids can be infused into the patient. These fluids can include normal saline, medicinal compounds, and/or nutritional compositions (including total parenteral nutrition, or "TPN"). Fluids, such as blood samples, can also be removed from the patient's circulatory system through catheter 12 to monitor conditions internal to the patient's vascular system.
    [026] In some embodiments, a needle septum 22 is disposed within the catheter adapter 14 to prevent fluid extravasation during and after removal of the introducer needle 20. The needle septum 22 may be elastomeric and be designed to adapt up fully to the shape of a 20 introducer needle and prevent leakage. Needle septum 22 can also form a seal after needle removal due to axial compressive forces on needle septum 22 that induce it to close.
    [027] In some cases, fluids may be infused and withdrawn from catheter 12 through a port 30 in a side wall 32 of the catheter adapter 14. Port 30 may form an opening 34 that extends through a wall. side 32 of catheter adapter 14. Side wall 32 may be any wall of catheter adapter 14 that extends substantially in longitudinal dimension (relative to longitudinal axis 24) along catheter adapter 14. A port 30 it can be a side door or a top door. Port 30 can form a fluid path from the external environment to the inner lumen 16 of catheter adapter 14.
    [028] To prevent contamination from entering catheter adapter 14 through port 30, a valve 40 can be coupled to port 30, which provides selective access through port 30. In some embodiments, valve 40 may be a bidirectional valve. A bi-directional valve is a valve 40 that allows fluid to flow in two directions through valve 40 when valve 40 is opened. Non-limiting examples of bidirectional valves include split septum, ball valve, and diaphragm valve. As such, the bidirectional valve can allow fluid to be introduced into catheter adapter 14 (a first way) and withdrawn from catheter adapter 14 (a second way). In other embodiments, valve 40 consists of a one-way valve, with valve 40 being the one that exclusively permits substantial flow of fluid in a single direction when valve 40 is opened. A non-limiting example of a one-way valve is a check valve. In some embodiments, no other valve is used in regulating fluid flow through port 30, only valve 40. By thus positioning valve 40 in a port 30 of catheter adapter 14, valve 40 can avoid problems caused by introducer needle 20 when left in the valve in-line for prolonged periods.
    [029] In some configurations, the port 30 may be disposed at an angle 42 to the longitudinal axis 24 of the catheter adapter 14. The angle 42 may be measured between the portion of the longitudinal axis 24 that extends to the end. proximal of catheter adapter 14 and central axis 38 of port 40. For example, angle 42 of port 30 of Figure 1 is approximately 90° and angle 42 of port 30 of Figure 6 is approximately 45°. Angle 42 can control, at least partially, the direction in which fluids are infused through port 30. In this way, angle 42 of port 30 can be modified to facilitate use, improve performance, and/or improve the flow of fluid within inner lumen 16. In some embodiments, the angle 42 is between about 15° and 30°. In other embodiments, the angle 42 is between about 30° and 45°. In still other embodiments, this angle 42 is between about 45° and 60°. In other embodiments, the angle 42 is between about 60° and 90°. Therefore, in some embodiments, the angle 42 is between about 15° and 90°.
    [030] The port 30 may include a port body 36 provided with one or more integral body parts which extend outwardly from the side wall 32 of the catheter adapter 14. Typical plastic materials such as, for example, polycarbonate, polyethylene, polypropylene and copolyesters could be used to form the port body 36. The port body 36 can define an inlet 44 and a hole 48 that extends between the inlet 44 and the opening 34 of the inner lumen 18. The inlet 44 and at least a portion of bore 48 may be shaped and sized at least in accordance with some International Organization for Standardization (ISO) standards relating to a female luer connection. This will allow a male luer strip or male luer latch to be attached to port 30.
    [031] In various embodiments, the exterior of the port body 36 may include one or more threads of the luer 50 in any number of available thread configurations to provide mutual locking between compatible devices. The threads of luer 50 may allow other medical devices that have a male luer latch to be connected and locked to port 30. Alternatively, as shown in Figure 9, port body 36 may also not contain luer threads that engage. modem luer strap connections and luer latch.
    [032] Figures 1 to 9 illustrate various types of valves 40 that can be used according to various modalities of port 30. These valve types are not presented as a limited set of valve types and, therefore, it will be understood that other suitable valves 40 may be used in port 30. We will first refer to valve 40 of Figure 1. Valve 40 may include an elastomeric septum 56 capable of forming a barrier to fluid until it undergoes deformation. that promotes fluid flow through it. Septum 56 can be located at inlet 44, inside inlet 44, or inside hole 48 of port body 36. Materials such as silicone, silicone rubber, or polyisoprene can be used to form septum 56 The septum 56 can be formed as a single piece of elastomeric material formed to incorporate various shapes and features. Alternatively, the septum 56 can take on a two-component configuration that has a flexible inner material, such as silicone or silicone rubber, and a stiffer outer portion, such as an outer ring. The outer ring can be formed from plastic or metal or other suitable material. Septum 56 may further include a slit 58. In some configurations, at least a portion of septum 56 is glued to port body 36 using one or more adhesives. Additionally or alternatively, in some configurations, at least a portion of the septum 56 remains secured between two or more portions of the port body 36.
    [033] Figure 2 illustrates a top perspective view of the catheter assembly 10 of Figure 1. As shown, the port 30 can be accessed with a male luer device (such as the luer access connector 80 of the Figure 6) which is inserted through slit 58 of septum 56. The male luer device can be locked with the luer threads 50, if the male luer device includes a luer lock. In this way, a separate access device can be coupled to catheter adapter 14 through port 30 to establish fluid communication therethrough. Additionally, a syringe, needle, or such device can be inserted into the slit 58 of the septum 58 for fluid extraction.
    [034] At this time, Figures 3 to 5 will be considered. These figures illustrate the use of manual override valves 40 that can control fluid flow through port 30. We will first look at Figure 3, which illustrates a ball valve 60 including a ball member 66 disposed in bore 48 of port 30 The ball member 66 may have an orifice 64 passing through it, so that when the orifice 64 is aligned with the central axis 38 of the port 30, the ball valve 60 opens. By rotating the ball member 66, for example, with an actuator 62, the orifice 64 is perpendicular to the central axis 38 of the port body 36 and the ball valve 60 closes. An actuator 62 can be coupled to the spherical member 66 so that, while the actuator 62 is rotated, the spherical member 66 is moved between the open and closed positions. In one configuration, as shown, actuator 62 includes grip portion 68 which is shaped and sized to accommodate a medical professional's fingers and act as a lever for rotating actuator 62.
    [035] Some embodiments of ball valve 60 are configured so that orifice 64 through ball member 66 conforms to at least some of the ISO standards for a female luer connection as described above. This configuration would allow the insertion of a male luer into the hole 64 of the spherical member 66 while the male luer is inserted into the port 30. Additionally, as shown in the figure, a cap 70 can be removably coupled to the port inlet 44 of the port. 30. Cover 70 can cover inlet 44 and prevent ingress of contamination.
    [036] Figures 4 and 5 illustrate another manual activation valve 40, a diaphragm valve. Figure 4 illustrates a cross-sectional view of diaphragm valve 72. In general, diaphragm valve 72 would include a series of plates 74 capable of folding over one another and expanding outwardly to open and close the door. 30. When actuated, this series of plates 74 may gradually open to provide a variable sized opening through diaphragm valve 72. Figure 5 illustrates a top perspective view of diaphragm valve 72. diaphragm 72 remains in a closed position and the series of plates 72 forms a barrier transverse to port 30 that seals opening 34 to inner lumen 16 of catheter adapter 14. An actuator 62 can be coupled to diaphragm valve 72 in a manner whereas, while actuator 62 is moved, diaphragm valve 72 is moved between the open and closed positions. In some configurations, as shown, actuator 62 includes grip portion 68 that is shaped and sized to accommodate a medical professional's fingers and act as a lever to rotate actuator 62.
    [037] At this point we will refer to Figure 6, which illustrates a port 30 with a central axis 38 arranged at an angle 42 of approximately 45° to the longitudinal geometric axis 24 of the catheter adapter 14. As shown in the figure, in some In embodiments, port 30 may be coupled to a removable valve 40. Removable valve 40 may be selectively coupled to port body 36, for example, through the threads of luer 50. For example, removable valve 40 may be coupled to a removable luer access connector 80. A non-limiting example of such a luer access connector 80 is described in Published U.S. Patent Application No. 2003/0109853, filed December 7, 2001, and entitled “Needleless luer access connector”, which is hereby incorporated by this quotation in its entirety. Other gender luer 80 access connectors can also be used. As shown in the figure, some embodiments of a luer access connector 80 may include a housing 82 containing an upper housing 94 and a lower housing 96. A septum 84 may be located on top of housing 94 of the luer access connector 80 to control fluid flow therethrough. The septum 84 may include an upper portion 86, a middle portion 88, and a lower portion 90. The lower portion 21 of the septum 84 may be disposed and/or maintained tensioned between the top of the housing 94 and the portion of the septum. under housing 96. Additionally, a slit 92 may be formed in septum 84, extending in longitudinal dimension through proximal portion 86, middle portion 88, and distal portion 90 of septum 84.
    [038] The bottom of the housing 96 of the luer access connector 80 may have an outlet 100 that is sized and configured as a male luer taper in accordance with ISO standards regarding a male luer taper and therefore can be inserted into hole 48 of port 30. In addition, the underside of housing 96 may include a bead of luer latch 98 formed around outlet 100 to selectively lock luer access connector 80 to luer threads 50 of the door body 36.
    [039] Looking at Figure 7, in some embodiments, the top part of the housing 94 of the luer access connector 80 is connected directly and/or fixedly to the body of the door 36. This configuration allows to reduce the overall size and the number of required parts included in port 30.
    [040] Figure 8 depicts a cross-sectional view of the catheter assembly of Figure 7 taken along line 8-8 of Figure 7. As shown in the figure, in the modalities in which the top of the housing 94 of a valve housing 82 is directly connected to the port body 36, the lower part 90 of the septum 84 can remain tensioned between the top of the housing 94 and the port body 36. Furthermore, to ensure this connection , the top of the housing 94 and the door body 36 can be joined together to prevent contamination of the door 30. Any conventional joining technique, such as chemical adhesive or ultrasonic welding, can be used to joining the top of the housing housing 94 to the door body 36. Additionally, as shown, the shape and size of the door body 36 can be configured to accommodate movement of the septum 84.
    [041] As Figure 8 further shows, in some embodiments, a port 30 and valve 40 are used with a catheter set that promotes blood control 10. Blood control catheter sets 10 generally include a blood control septum. 110 disposed within inner lumen 16 of catheter assembly 10. Blood control septum 110 can be opened by a septum activator 112 when a luer device (not shown) is inserted into the proximal end 28 of catheter adapter 14. The luer device can advance the septum activator 112 distally through the blood control septum 110 to form an open fluid path therethrough. A catheter assembly that promotes representative blood control is disclosed in U.S. Published Patent Application No. 2011/0046570 entitled "Systems and Methods for Providing a Flushable Catheter Assembly", filed on August 20, 2009, which is hereby incorporated by this quote in its entirety.
    [042] A valve in port 30 can confer numerous benefits to blood control catheter assemblies 10. For example, a blood control septum 110 may remain open after the septum 112 activator is inserted through the blood control septum. 110. This blood control septum 110 can remain open even after the male luer that has advanced the septum activator 122 is removed. In this open state, fluids can leak from the catheter adapter 14 and be exposed to the medical professional. However, using the valve in port 30, the medical professional can access the inner lumen 16 of the catheter adapter 14 without being exposed to the patient's blood.
    [043] At this point we will make a specific mention of the components of the catheter assembly that promotes blood control 10 represented in Figure 8. As shown in the figure, a catheter assembly 14 may have a blood control septum 110 located within the inner lumen 16 of catheter adapter 14. A septum activator 112 may be located within inner lumen 16 behind blood control septum 110. Blood control septum 110 may generally comprise a flexible polymer plug or semi-flexible. The blood control septum 110 may have an outer diameter configured to fit compatibly within the groove or channel 114 formed on the inner surface 116 of the catheter adapter 14. Alternatively, a groove or channel may be formed in the outer surface of the septum. of blood control 110, which will lock to one or more features on the inner surface 116 of the catheter adapter 14. In some embodiments, blood control septum 110 is barrel-shaped, and in other configurations, blood control septum 110 it takes on a substantially cylindrical or discoid shape. Blood control septum 110 can be elastomeric and include one or more slits 118 through which septum activator 112 can be inserted.
    [044] The septum activator 112 may be a probe-like structure that basically remains housed behind the septum 110 within the internal lumen 16 of the catheter adapter 14. The septum activator 112 generally comprises a rigid or semi-rigid tubular body 122 . The tubular body 122 further comprises an internal lumen 124 to facilitate the flow of a fluid and/or liquid through the septum activator 112. The distal end of the tubular body 122 may be shaped and sized to compatibly penetrate one or more slits. 118 of the 110th sept.
    [045] Referring now to Figure 9, in some cases, as shown in the figure, the outside of the port body 36 may be devoid of luer threads. This would allow a luer access connector 80 or other separate luer device provided with a male luer nip to be connected to the port body 36. This type of port 30, therefore, can enable a wide variety of devices to be connected to it. Also, in some cases, a septum 56, such as that shown in Figure 1, may be included in port 30 to prevent exposure of blood when the separate luer device is removed from port 30.
    [046] Referring now to Figure 10, in some modalities, the septum 112 activator of a set of catheters that promote blood control 10 can be activated and/or deactivated by pressing a button 130 on port 30. button 130 may allow the medical professional to manually activate and deactivate septum 110 as needed. In operation, septum activator 112 may be advanced distally through septum 110 when button 130 is pressed a first time, and withdrawn from septum 110 when button 130 is pressed a second time. In some configurations, button 130 is coupled to sidewall 32 and extends outwardly of catheter adapter 14. In addition, button 130 can be coupled directly or indirectly to septum activator 112 via one or more connecting members. . For example, button 130 may be coupled to one or more translation mechanisms 134 that translate movement of button 130 inwardly into distal or proximal movements of septum activator 112.
    [047] From the foregoing description, namely that a catheter assembly of the present invention may include a valve located in a port of a catheter adapter instead of aligned with the needle trajectory of an introducer needle. This valve in a port can avoid the problems caused when a needle is left in the septum for an extended period and still provide the ability to infuse and extract fluids through the port. This valve can be a bidirectional valve that facilitates the infusion and extraction of fluids from the catheter set. When used in conjunction with blood-controlled catheter assemblies, the valve can reduce the likelihood of blood contamination when connecting and disconnecting various components to the catheter assembly. Some configurations even include a push-button septum activator that can provide the physician with the ability to manually activate and deactivate the blood controls valve as needed.
    [048] The present invention can be incorporated in other specific ways without deviating from its structures, methods or other essential characteristics in the form fully described in this document and claimed below. The described modalities must be considered, in all their aspects, as merely illustrative and not restrictive. The scope of the invention, therefore, is especially indicated by the attached claims, surpassing the descriptive report that precedes it. All changes contained in the meaning and equivalence range of the claims will be embraced within their scope.
