    [0001] Device for contraception in man.
    [0002] Technical field
    [0003] [0001] The invention relates to a device for contraception in man, particularly a device for the temporary interruption of sperm flow within the vas deferens (ductus deferents or vas deferents) of man.
    [0004] State of the art
    [0005] [0002] For the regulation of reproduction by man there is the known, not exempt risk condon and vasectomy that although safe is almost definitive. The inversion of a vasectomy is linked to a great cost and is not reversible in a safe way. That is why in most cases it is only chosen after the desired number of children has been had. Recently, the number of men who underwent a vasectomy years ago has increased and they now want to revert it again due to changed situations.
    [0006] The development of drugs that act in a hormonal way, which should influence the fertility of man, according to various media communications by international pharmaceuticals, has been suspended due to lack of perspective.
    [0007] [0003] Devices for temporary interruption of sperm flow can be implanted in the vas deferens in the scrotum (scrotum) of man.
    [0008] [0004] US Patent 4,200,107 discloses a cylindrical cup connector, which is fixed to the vas deferens. The patent US 6,513,528 describes a silicone cylinder to be introduced into the vas deferens. To revert again the closure of the vas deferens, it is necessary respectively in both cases to perform another operation. Patent application PCTWO 2010/047644 A1 describes a very expensive technical solution, in which the closure of the channels that conduct the semen is carried out by means of a collar to be implanted that presses on the channels, where the collar is handled by a device of pumping that must be implanted too. This pumping device is controlled and supplied with energy from the outside by the skin of the user. For this, a remote control and an inductive power transmitter are additionally required. Implantation requires a high cost, as among others for the elimination of pain requires at least a spinal anesthesia. This leads to high costs of the operation and a greater risk to the patient's health. In addition, the large number of mechanical, hydraulic and electronic components necessary increases the risk of technical failure, and other energy costs arise for the commissioning of the device.
    [0009] [0005] The patent DE 19909422 C1 represents the state of the closest technique and describes a valve that is implanted in the vas deferens of man and can be felt by a switch handle through the scrotum of the user and thus can be open or close. They are constructed in such a way that the user is able to influence it externally in their ability to generate without other surgical interventions. US patent 8,616,212 discloses a valve, which can be inserted into a vas deferens or a fallopian tube and serves to control the birth rate. The valve can be opened and closed manually with a rotating arm or can be operated by remote control by means of a solenoid and radio receiver. A variant presents magnets that can be moved by a magnetic field on the rotating arm. Closing the valve blocks a passage for the flow of sperm or an egg.
    [0010] Description of the invention
    [0011] [0006] The present invention has the task of creating a device for closing the vas deferens of a man for contraceptive purposes, which compared with such devices of the state of the art, is improved, particularly with respect to the valve circuit.
    [0012] [0007] This task is solved with a device with the features of claim 1.
    [0013] [0008] The device according to the invention is hereinafter referred to as the vas deferens valve. A valve of deferent vas deferens insertable for the contraception in the male or male animal for the adjustment of the flow of sperm in the vas deferens, in Latin ductus deferents or Vas deferents, within the scrotum is disclosed. It comprises a valve and two valve splice terminals, which can respectively be attached to the testicular and abdominal end of a previously separated vas deferens, where the testicular end of the vas deferens leads to that end of the testes, in Latin Testis, and the abdominal end towards the lower abdomen, in the abdomen abdomen. The valve has a manual switch, with which on the one hand the connection status of the valve can be checked from the outside by palpation and on the other hand it can be changed between an open and closed state. According to the invention, the valvula of the vas deferens presents a passage channel and at least one drain channel, where the passage channel in the open state of the valve leads from the connecting element of the valve in the testicular vas deferens to the connecting element of the valve at the abdominal end of the valve. different conductor. In the closed state of the valve is closed the end of the flow channel that is oriented towards the end of the abdominal deferens driver. The at least one drain channel leads in the closed state of the valve from the connecting element of the valve at the testicular end of the vas deferens out of the valve and into the interior of the man's body.
    [0014] [0009] In one embodiment of the invention, the valve switch of the vas deferens is formed as a switch balancer.
    [0015] [0010] In another embodiment of the invention, the valve of the vas deferens has an unlocking pin, which must first be actuated to open the valve.
    [0016] [0011] The invention has the advantage that in the closed state of the valve only the abdominal end of the vas deferens is closed, while the testicular end of the vas deferens is open and the transport of semen from this end can be performed without hindrance. . In addition, the drain channel or the various drainage channels allow the discharge of sperm coming from the testicular end of the deferential conductor, which consequently leave the valve and its casing and can reach the man's body. Accordingly, because of the valve according to the invention there is no retention of outgoing sperm in the epididymis area. Instead, the sperm reaches the tissue in the scrotum and is released there by the body's own mechanisms.
    [0017] According to today's knowledge, this has no pathological effects.
    [0018] [0012] Because there is no risk of retention of semen, the vas deferens valve according to the invention can be implanted at any point in the scrotum area in the vas deferens. It is not strictly necessary to place the implant so close to the epidphdimus. This has the advantage that the implant can be placed by the surgeon at a point, which best corresponds to the patient. The invention is a passive implant within the vas deferens (ductus deferens) in the scrotum (Scrotum) of man. The placement of the valve only requires a simple operation, low risk, economical, ambulant, using local anesthesia, similar to a vasectomy, which can be performed by any properly trained urologist.
    [0019] As in the case of vasectomy, the vas deferens are separated and the two ends of the vas deferens that arise in this way are displaced and fixed on the valve's intended splice terminals. The valvula of the vas deferens can therefore move freely together with the vas deferens fixed to it and the testes in the scrotum. The valve always comes into service in pairs, since there are usually also two tests (Testis).
    [0020] [0013] The valve has been constructed in such a way that the status of the valve switch, that is, open or closed, can be verified by the same user and without surgical intervention by palpation from the outside through the soft skin of the valve. scrotum, and if necessary can be modified by the switch balancer drive.
    [0021] With the drive the mechanics fit respectively accurately, safely and appreciably in a respective final position: open or closed.
    [0022] In this case, in the open or closed positions of the valve, for example, the surfaces of the switch rocker are aligned with the surface of the body of the valve.
    [0023] [0014] The valve is linked to the direction. This means that in the implantation it is necessary to take care that the abdominal end of the vas deferens is also fixed to the abdominal end of the vas deferens and in the same sense the testicular end of the vas deferens valve is also attached to the testicular end of the vas. different conductor.
    [0024] For this, as usual in all the technical valves, a mark of the direction of flow is introduced by arrow. The applied arrow therefore points always in the natural direction of the ascending flow of sperm towards the direction of the lower abdomen of the persons, abdominal in latfn.
    [0025] [0015] By palpation it can be checked whether the valve is open or closed.
    [0026] The valve is open, if the surface of the switch rocker on the abdominal side of the valve is aligned with the body of the valve and the edge of the rocker switch on the side of the testicles protrudes over the body of the valve.
    [0027] The valve is closed, when the surface of the switch rocker on the test side is aligned with the valve body accurately and the abdominal edge of the switch rocker protrudes above the body of the valve.
    [0028] [0016] To close the valve, the erect switch balancer on the side of the valve that points towards the test muscle, moves by a rolling movement in the direction of the testicles.
    [0029] In this way, the edge of the switch rocker that points towards the body or the abdomen is incorporated and the position of the valve fits in a fixed manner.
    [0030]
    [0031] [0017] In order to open the valve, the unlocking pin is pressed on the lower angle of the valve pointing towards the testicles and the switch rocker moves with a rolling movement in the direction of the vas deferens leading to the body.
    [0032] Thus the switch rocker rises on the testicular side of the valve leading to the testicle.
    [0033]
    [0034] [0018] In the closed state itself, as in the case of vasectomy, an almost complete ejaculation occurs, since only a part, approximately 3-5% vol., Of the testicles is missing. The palpation and switching of the valve works in the best way when the scrotum has an extended and soft state. The scrotum serves to regulate the temperature of the testicles. For optimal spermiogenesis, they need a temperature of about 3 ° C below the temperature of the human body. In the case that the temperature of the environment is cold, the scrotum is contracted to heat the testicles. In case of warm to warm conditions, it expands and enlarges its surface to cool the testicles. That is why the user is careful that a desired switching of the vas deferens valve takes place to warm up the region of the testicles. The switching position chosen should be logically equal in the two valves. The valvula of the vas deferens in the scrotum can not be recognized from the outside, since the vas deferens always come from the back side of the testicles.
    [0035]
    [0036] [0019] The invention creates a simple and safe means by which man can determine the same at any time, if he wants to be a father in a given life situation. In a situation of heterosexual couple is alone in the position and can deal with if and when and in what time interval wants to father a child. This is allowed with the invention, as soon as the switch according to the invention is overturned. You do not have to take medications or hormones and there are no permanent costs. Your partner does not need to risk your health because of the use of contraceptives. The man does not have to renounce sex or use utensils or make them available. The invention disclosed herein is a recent medical product for the contraception of man and therefore should or may be designated correctly contragenerative. This concept still does not exist in the nomenclator. Only this shows that in the circles of experts it is based on the fact that birth control is a matter for women. Because for the woman there are innumerable possibilities of contraception. The use of these means is always related to side effects and risks. The invention described herein therefore represents an alternative to the preceding birth regulations. This allows man to assume only birth control.
    [0037] Because of the simplicity, high security, minimal side effects and risks and low costs can be used in a general way.

    [0061] EXAMPLES OF EMBODIMENT OF THE INVENTION
    [0062]
    [0063] [0023] The valve of the vas deferens 22 according to the invention can be implanted in the man in the scrotum 19 in the vas deferens 16,17 as shown in figure 1. The vas deferens from the testes 20 for this first of all separates, where the end in the testicular part of the vas deferens 16 and the end in the abdominal part of the vas deferens 17 do not close, as is done approximately in the case of a vasectomy. The valve of the vas deferens 22 is implanted in the representation between the epidphdimus 21 and the seminal gland (Glandulae vesiculosa) 23 but still in the area of the scrotum 19. It does not necessarily have to be next to the epidphdum 21. The valve of the vas deferens 22 consists of a body of valve 1 with side walls 3, connecting parts of the valve connected to the testicular and abdominal ends of the vas deferens 16 and 17, as well as a switch balancer 2 and a release pin 10. The valve of the The vas deferens, like the testicles and the vas deferens can move freely in the scrotum, in correspondence with the corporal drive of any type of man. As shown in FIGS. 2-5, the invention consists of a valve body 1, which serves to house valve connection elements 9 arranged laterally and facing each other, shown in FIGS. 2 to 5 to FIG. right and to the left with valve caps 4, as well as on the balancer switch 2 and the other mechanical parts. The body of the valve 1 has for example the shape of a parallelepiped with corners and edges rounded everywhere, partly sharply. The roundings avoid a traumatization of the surrounding tissue. The body of the valve 1 has, for example, a length of approximately 18 mm, a height of 10 mm and a depth of approximately 7 mm. But dimensions of up to 50% or greater are also imaginable. The smaller the valve, the greater the comfort of transportation. However, the operational ease of the switch balancer 2 is reduced and vice versa. The indicated dimensions were tested in autoassay and have been confirmed as a good compromise solution.
    [0064]
    [0065] Most of the parts consist preferably of implant plastic such as (for example, PEEK) and they are worked in CNC milling technique or in injection molding microtechnics. Valve connections 9 can be made of metal alloys, such as for example titanium alloys (eg Nitinol) or a suitable implant steel (eg 1.4441 / 316 LVM material), or of plastic or a combination of both types of material. The grid-shaped tube 9c, however, can also be made, for example, of metal and can be inserted into the parts 9b consisting, for example, of plastic 9a by injection molding. The necessary compression springs can be made of platinum alloys or implant spring steel.
    [0066]
    [0067] [0024] The body of the valve 1 has in the upper third in longitudinal direction a passage channel 1a of a diameter of approximately 0.7 mm, which extends through the switch rocker 2 and the connecting elements of the valve 9 and that can take place through the open state of the sperm flow valve. On the front parts of the parallelepiped valve body, axially to the passageway 1a, cuneiform mills 1d are milled and shaped in the form of circular tracks 1e for the housing of the valve caps 4 and gradual perforations 1b for the housing of the elements of the valve. Valve 9 connection during implantation. Transversely to the passage channel 1a and starting from the large surface 3 of the valve body is a large gradual drilling which is perpendicular to the passage channel 1a, of for example a diameter of 12 mm and a depth of 5 mm. On the same equal axis and at the bottom of the gradual drilling is a smaller blind hole, for example, a diameter of 2 mm and a depth of 0.7 mm. This small blind bore serves for the housing and the rotary bearing of the switch rocker 2. The large, gradual drilling crosses the upper edge of the valve body, whereby the mounted switch rocker 2 protrudes above the body of the valve. In the lower area of the gradual drilling, two recesses of the same shape 1c are located in the perforation wall, which are reciprocally symmetrical and each have at least one circular segment shape. They serve as a guide and stop for a splined wheel axle 7, which brings the switch rocker 2 to the two end positions. The wheel axle 7 serves for the switching of the switch balancer 2. It has the shape of a weight. In the area of the shaft and by means of the shaft spring 13, a normal compression spring is pressed out of its guide on the switch balancer 2. In this way, the pairs of wheels on the shaft have to automatically follow the shape of the cutouts 1c in the body of the valve 1 and thus force the switch rocker 2 in the respective end stop towards "Open" or "Closed." In this way the valve can only adopt a completely closed or completely open state.
    [0068]
    [0069] [0025] At the lower left angle, at the angle of for example 40 [deg.] With respect to the passageway 1a, a gradual continuous drilling and a cuneiform notch for housings of a safety device is provided, which consists of an unlocking pin 10, an unlocking pin spring 15 and a safety plate 14.
    [0070]
    [0071] The body of the valve in the form of parallelepiped 1 has round and perforations a main sickle-shaped surface. On this narrow ridge are several, for example 6, cylindrical pins. For example, by means of the ultrasonic spot welding technique, the body of the valve 1 can be connected to the cover of the valve 3. In this way the cover of the valve 3 consequently terminates the technique of the total valve towards the outside.
    [0072]
    [0073] [0026] The balancer switch 2 has the form of a cylinder of lower height, whose cylinder liner is oriented towards the valve connections, as well as a cylinder bottom and cylinder cover, which are oriented parallel to the side walls. 3 of the body of the valve. The cylinder sleeve of the switch rocker 2 has a recess with surfaces 2a and 2b, which barely extend over a quarter of its perimeter. The cutout in the switch rocker 2 therefore consists of two surfaces 2a and 2b perpendicular to the cylinder cover and bottom of the cylinder, which form the angle of the recess, for example 140 °. The surface 2b is in the open position of the valve 22 aligned with the body of the valve 1 while the surface 2a projects above the body of the valve. In closed position the surface 2a is aligned with the body, while the surface 2b projects. In addition, the surface 2a is located near the testicular inlet end of the valve (the inlet end of the valve is designated in Figure 2-4 with the "Flow" arrow pointing inward on the valve), where with the closed valve extends at the entrance end aligned with the body of the valve. Correspondingly, the surface 2b is located near the abdominal outlet end of the valve and extends with the valve open aligned with the body of the valve at the outlet end of the valve. (The exit end of the valve is indicated in figure 2 and 4 with the arrow "FloW 'pointing out of the valve).
    [0074]
    [0075] The switch balancer 2 is rounded on all sides and has several perforations. From there, a first drilling 2c takes place parallel to the cap and floor of the cylinder and through the center of the cylinder 2 and parallel to the surface 2b. This perforation allows the flow of sperm in the case of an open valve 22 and for this it houses displacement tubes with an outer fold 5 and a displacement tube with an inner fold 6, which are pressed outwards by a compression spring 11. This arises because of the spring and the geometry adjusted in a domed manner of the outer front surfaces of the displacement tubes 5 and 6 and their perforations 5a and 6a next to the passage perforations 1a in the body of the valve and the perforation 9a in the valve connecting element 9 an outwardly sealed passage for the sperm in the open state of the vas deferens valve 22. Other perforations 2d and 2f also extend parallel to the cylinder cover and lead from a first orifice in the Cylinder jacket in the area of the end of the inlet 4a of the valve axially to the gradual perforation facing 2g of the valve and from a second vertical perforation in the surface 2a towards the interior of the switch rocker 2, where the perforations 2d and 2f are at an intersection point. Another perforation 2e cuts this intersection point forming a right angle with these perforations 2d and 2f and is aligned with a perforation on the side of the valve 22 that leads outwards.
    [0076]
    [0077] In the closed state of the vas deferens 22 the perforation 2e is also aligned with a perforation 3a in the cap of the valve 3 and this perforation is exactly opposite in the wall of the body of the valve 1. The perforations previously mentioned serve for the evacuation of the sperm towards the outside or inside the scrotum 19, in the case of the closed valve.
    [0078]
    [0079] The two surfaces 2a and 2b form the palpation surfaces for the switching of the valve 22. If pressed on the surface 2b for "Open", the balancer switch 2 rotates in the body of the valve 1 at a predetermined angle , for example 40 °, and fits in this point in a fixed and suspended manner. A pressure on the other surface 2a for "closed" causes the balancer switch 2 to jump again at 40 ° to the other direction. The switch rocker 2 takes a blocking pin 8 and a pin spring 12 as sealing elements in a blind hole drill 2g. The drilling axis of the stepped blind bore hole 2g for receiving the locking pin 8 and the spring of the pin 12 extends parallel to the surface 2a "Closed" and crosses the vertical or vertical axis of the balancer at a right angle. cylindrical switch 2. The arrangement of the displacement tube with perforations 5a and 6a is at the same predetermined angle, eg 40 °, with respect to the axis of the perforation for the locking pin 8 and thus in parallel with the Surface 2b "Open".
    [0080]
    [0081] In the other drilling 2h, which is introduced diametrically to the surface 2a and 2b, there is the spring of the wheel axle 13, which removes the wheel axle 7 from the switch rocker 2 and ensures that it is locked. The wheel axle 7 is guided for this purpose in guide grooves accurately measured on the balancer switch 2 in the area around the perforation 2h. In addition, at this point of the switch rocker 2 two recesses 1c are arranged in the valve body, in which the suspended wheel axle 7 with simple play and displacement path measured accurately is housed. The recesses are formed in the sides facing the connecting elements in the form of a circular segment, so that the axis of the wheel 7 is retained. On its side facing the center of the valve, the recesses 1c each have a surface Angled upwards to switch switch 2, which are located on the center line of valve 22.
    [0082]
    [0083] [0027] In this case, the axis of the wheel 7 is housed in the closed valve position in the recess 1c on the outlet side (in the figure on the left side), whereby in the case of switching of the valve 22 it moves to the notch on the side of the entrance 1c and is housed there (in the figure on the right side). The displacement tube with outer fold 5 and the displacement tube with internal fold 6, which are mounted on the balancer switch 2, are manufactured in such a way that they can be inserted one inside the other and separated from each other by the compression spring 11, a normal compression spring. This causes a sealing of the passage channel 5a and 6a towards the passage channel 1a of the body of the valve 1. The ends of the displacement tubes projecting outwards additionally possess a vaulted geometry, corresponding to the shape of the large gradual drilling in the body of the valve 1. In the event that the valve is open, the disposition of the displacement tube extends in the same axis with the passage of the valve. In the event that the valve closes with a turn of -40 ° of the switch balancer 2, the orifice of a displacement tube is shown to the outside. The other displacement tube fits to the right at the bottom of the hole in the safety plate 14. In the event that the valve must be closed, first the unlocking pin must be pressed from the outside and below against the resistance of the valve. an unlocking pin spring 15. Only then can the valve be opened simultaneously. The unlocking pin 10 has, like the displacement tubes, a through-hole 10a and allows the cavities to be taken through the surrounding body fluid of the displacement tubes in the closed state of the valve. A safety plate 14 is a trapezoid-shaped insert which is shaped in a bulge towards the inside and with a gradual drilling and during the assembly of the valve moves to the appropriate recess in the body of the valve 1 after introducing the unlocking pin 10 and the spring of the unlocking pin 15. The spring of the unlocking pin 15 can be realized as a multi-piece disc spring or as a normal compression spring. With the variant of the disk springs, a click effect can thus be achieved, which indicates the unlocking of the unlocking pin 10.
    [0084]
    [0085] The true waterproofing of the sperm flow by the closed valve is guaranteed by the locking pin 8. When the valve is closed, it moves in front of the abdominal transit hole inside the valve, that is, the exit orifice of the valve. in the area of its outlet end. Correspondingly the outlet end of Figure 5 in the case of closure is indicated by a "Stop" arrow, where the sperm however flows through the drain channel 2f, 2e, and 2d. The locking pin 8 is pressed by the spring of the pin 12, a normal compression spring, against the large wall of gradual drilling of the valve body and has the same vaulted geometry on the contact surface with the body of the valve 1.
    [0086]
    [0087] In this way, it is not necessary for the valve of the deferent conduit 22 to have elastic sealing materials that wear out. Contrary to what is usual in valves, it does not become permeable in the case of much use. Through the reduced friction in the area of the track, which describes the locking pin in the body of the valve 1, both sides are inculcated one on top of the other and therefore they are increasingly watertight. On the other hand, with this low connection frequency of presumably less than 10 times within the useful life, the expected wear is negligible.
    [0088]
    [0089] For a sperm with a head diameter of approximately 3.5 microns, this barrier is insurmountable. Maxime when the sperm is in the area of the vas deferens still in an acid block, that is, can not move by itself.
    [0090]
    [0091] [0028] A cylindrical pin (not shown) on both sides of the switch rocker 2, protruding above the surface of the cylinder cover or cylinder bottom, serves respectively as a rotary axis at the center point of the switch rocker 2. . The pins fit in the blind hole perforations (not shown) of the valve body on one side and in the blind hole drilling of the valve cover 3 on the other hand.
    [0092]
    [0093] The cover of the valve 3 is in principle a reflection of the large side wall of the valve body. Close all mechanics after assembly out. For this purpose, it has several holes 3b, for example 6, for receiving the corresponding pins in the body of the valve 1, in order to be welded together with this with precise adjustment. Alternatively, however, the cover of the valve 3 could also be screwed to the body of the valve 1 or joined to the body of the valve 1 by means of a latching technique.
    [0094]
    [0095] [0029] As shown in FIGS. 6-9, the connecting elements of the valve 9 have a large flange 9b, which is locked in its slots 4a with the implantation of the lid of the two-piece valve 4. On the connecting side towards the body of the valve 1 is a cylindrical sleeve, which during the assembly of the unit consisting of the deferent conduit 16/17, valve connection 9 and the cover of the valve 2 of two pieces , it can be inserted in the perforation 1b of the body of the valve 1 according to figure 9. On the opposite side, for the insertion of the end of the respective deferential conduit, there is a small thin-walled tube 9c. The connection element of the valve 9 has a continuous orifice, which passes through the sleeves, flange and small tube and guarantees the flow of the sperm. In an embodiment of the invention (not shown) the small tube 9c has several precise conical steps as in a hose tube. In the implantation several different diameters of the small tubes are available with precise staging for the adaptation to the vas deferens. In another embodiment of the invention the small tube 9c is provided with a grid-like structure on the lateral surface. As in the case of a stent, the grid structure is somewhat compressed before implantation. In addition, this end is coated with a thin layer of silicone (not shown), for example, a silicone flexible tube or a similar elastic inert material, to guarantee the waterproofing of the inner mucosa of the vas deferens (mucosa) with the element of Valve 9 connection in the area from 9c to 9b. After introducing the connecting elements of the valve 9 into the deferent conduits 16, 17, these are amplified from the inside to the nominal internal dimension. This occurs by removing an elongate element 18 of type one with cuneiform head from the valve connecting element 9.
    [0096] [0030] In this way, the valve connection element 9 with a minimum external diameter can easily be inserted into the small lumen of the vas deferens. By means of special pliers not shown, which corresponds to the principle of a riveter, the element 18 is withdrawn from the valve connection element 9 and dilates the lumen of the valve connection in the area of the grid structure next to the vas deferens 16 , 17.
    [0097] [0031] Another variant of the widening of the grid structure in the valve connecting elements 9 with the inverse principle by the insertion of a cylindrical spine with a conical needle in place of the illustrated element 18 with the help of similar special pincers not shown either.
    [0098] [0032] The hollow cylinder-shaped valve covers 4 protect the deferent conduits 16, 17 in their rounded, domed shape from puncturing the valve connections in the event of abrupt movements. The lateral surfaces of the valve covers 4 are provided around them with perforations 4b, through which the ends of the vas deferens always remain in contact with the natural fluid of the surrounding tissue and the metabolism is allowed. A valve cover 4 consists of two halves, which are provided with hooks 4d and recesses. With its help, the two halves can be inserted and at the same time the valve connection element 9 can be fixed there.
    [0099] [0033] The two halves, when inserted, form a hollow cylinder. On the side towards the vas deferens 16, 17 has a large rounded edge and a protuberance facing inwards. The internal diameter of the heel should correspond to the outer diameter of the vas deferens. The valve covers 4 have a slot 4a inside to receive the flange of the connection of the valve 9. For this, a special pliers not shown is used, which is provided with a housing for the valve cover halves. In this way the two halves can be compressed safely, accurately and with force. The valve cap halves fit together.
    [0100] [0034] Furthermore, microneedles 4e have been incorporated into the halves. They are arranged in such a way that when compressing the halves of the valve cover perforate the muscular walls of the vas deferens tangentially and they enter holes incorporated in the half of the valve cover 4 facing, without leaving the other side. This provides a secure connection of the vas deferens valve to the vas deferens 16, 17, without compromising the blood flow of the vas deferens by a union or other seam. The large flange of the connection element of the valve 9 is embedded in the internal groove 4a of the halves of the valve cover 4.
    [0101] The resultant unit resulting from connection element 9, deferent conduits 16, 17 and valve cover halves 4 are finally inserted into the deferential conduit valve. Allf also fits thanks to the hooks 4f in the locking elements 1d and the recess 1e in the form of a circular groove in the valve body 1. The steps described in figures 6 to 10 occur both with the end of the abdominal vas deferens 17 and with the end of the testicular vas deferens 16. Thus an insoluble union of the vas deferens with the valve arises. This union could also be built in such a way that it could be resolved again by another special tool.
    [0102] For the vas deferens valve according to the invention, inert materials are preferably used. Thus, the surfaces of the individual pieces do not need anti-stick coatings or drugs for the prevention of rejection reactions of the human body.
    [0103] In an embodiment of the invention, a surface treatment limited to individual parts or extended to all parts of the vas deferens valve 22 is optionally provided for the aforementioned purpose.
    [0104] [0035] In order to be able to react to the different anatomical dimensions of the vas deferens 16,17 of different men, the valve connections 9 and valve caps 4 were correspondingly manufactured in different sizes. In this way, the surgeon can choose the right magnitude when the implant is used. The body of the valve itself, with the parts that are inside, could be the same size. In this way, an implantation of the vas deferens valve according to the invention is also suitable as an alternative for a vasovasostomy, when both ends of the vas deferens 16, 17 of a vas deferens have different dimensions, as is the case of years after a vasectomy.
    [0105] [0036] With the closing of the vas deferens valve the user is not sterile at the moment, but only after weeks to months. This does not have to be considered as a disadvantage. In the case that for example in a couple with children desire pregnancy is achieved, the valve closes. At the latest with the delivery of the child, therefore approximately generally 9 months after conception, the user is sterile. Other contraceptives on the part of the woman or of the man will not be necessary then. Only when more children are desired, for example after 2-4 years, do the vas deferens valves open. So it goes faster. Thus, sperm could be found in the ejaculate for example after 4 weeks or with the first ejaculation after the implantation of the vas deferens valve, although previously there had been one year of sterility.
    [0106] [0037] With the exception of condom, all contraceptives for man, including drugs and also the invention described herein, have the disadvantage that the user is not sterile immediately after activating the closing function or taking the medication. Sperm can remain weeks and even months in the organs that follow the respective device, such as prostate 25 and seminal gland 26 (Glandulae vesiculosa) and when it occurs with an ejaculation during intercourse, it can cause unwanted fecundation. Therefore, it is advisable to scientifically confirm the desired sterility previously by means of a spermiogram.
    [0107] In addition, these methods do not protect against infectious diseases.
