Description

[0001] Description

[0002] Title: Device for controlling the flow circulating in the lumen of a vas deferens of a male individual.

[0003] technical field

[0004] The present invention is in the field of mechanical contraceptive devices and more particularly reversible systems, that is to say, allowing a return to a fertile state after a contraceptive period.

[0005] State of the art

[0006] Devices aimed at mechanically controlling fertility in a male individual have been known for a long time.

[0007] The first category among these devices corresponds to single-use and / or disposable devices such as condoms. These devices are effective and reversible but are only suitable for human use. They also generate a very high amount of waste per individual, in addition to creating a mental burden since it is necessary to always have a device on hand to carry with you.

[0008] Another category concerns implantable devices, which can be used in humans or animals. While these partially address the problems associated with the first category of devices, most have significant disadvantages due to their inherent irreversibility or uncertain reversibility. The latter particularly concerns devices that require severing the vas deferens for implantation so that their ends can be connected to it.

[0009] Document EP 3128965 B1 presents an example of such a device.

[0010] Finally, some implantable devices that are inserted lengthwise into the vas deferens are known.

[0011] Document US3848578A provides an example.

[0012] Such devices, whether occlusive or not, cannot guarantee a proper seal and therefore cannot provide reliable contraception because the vas deferens is made of living biological tissue that is subject to varying pressures and can therefore contract or dilate. The fluid can thus bypass the device, rendering it ineffective. Summary of the invention

[0013] The invention aims to improve the situation described above.

[0014] The invention aims to overcome the drawbacks of the prior art by proposing a minimally invasive control device whose positioning does not require sectioning of the vas deferens, unlike vasectomy.

[0015] Another aim of the invention is to provide a reversible control device that allows the path of the flow from an upstream portion of the vas deferens, originating from the testicles and epididymides, to be temporarily modified.

[0016] Another aim of the invention is to provide a control device whose actuation requires the intervention of a healthcare professional, and with redundant safety features.

[0017] Another aim of the invention is to provide a control device that limits the risks of undesired disengagement of the vas deferens.

[0018] Finally, another aim of the invention is to offer an inexpensive control device which does not require complex equipment for its installation by a practitioner, and therefore allows the intervention to be carried out more quickly and in a simplified environment.

[0019] According to the invention, the device for controlling a flow circulating in the lumen of a vas deferens of a male individual comprises:

[0020] - a clamp configured to coaxially grip the outer wall of the vas deferens along an axis of the lumen F; and

[0021] - a long, slender element, configured to be coupled to the clamp, a distal part of which is able to be introduced at least partially into the vas deferens and has a deflection tube able to deflect said flow out of the vas deferens when an inlet of said deflection tube is aligned with the lumen.

[0022] Advantageously, the long element can be coupled to the clamp temporarily, i.e., be removable.

[0023] The vas deferens consists of a tubular wall with a hollow interior called the lumen, through which blood flows. The tubular wall of the vas deferens is composed of three layers, from the outside in: an adventitia, a muscularis, and a mucosa. The lumen is stellate. A human vas deferens has an external diameter between 2 mm and 3 mm, while its lumen has a diameter between 0.2 mm and 0.7 mm.

[0024] From a biological point of view, in mammals the vas deferens is vascularized by the deferential artery which is attached to the lower part of its wall and such a configuration makes techniques and devices requiring dissection of the vas deferens more hazardous compared to the device according to the invention.

[0025] Thus, the device according to the invention employs a clamp configured to coaxially grasp the outer wall of the vas deferens, preferably by means of a pair of jaws having, in the closed position, an air gap smaller than the diameter of said vas deferens and larger than the diameter of the vas deferens artery, and even more preferably an air gap at the free end of the clamp smaller than the diameter of said vas deferens and larger than the diameter of the vas deferens artery. The air gap, particularly at the free end of the clamp, is advantageously between 0.8 mm and 1.5 mm.

[0026] Therefore, there is no interaction with the artery or any possibility of injury to it. The clamp allows the device to be positioned at the desired location within the vas deferens, that is, more or less upstream or downstream along its length. By coaxially clamping the outer wall of the vas deferens, the clamp of the control device protects the area of ​​action of the linear element that controls the flow. When the vas deferens is at rest, the clamp grips it without compressing it, while when the vas deferens is aroused, it contracts and dilates, and the clamp helps to contain this dilation.

[0027] The elongated element has a distal portion designed to be at least partially inserted into the vas deferens. This distal portion is configured so that its dimensions are smaller than the overall diameter of the vas deferens and larger than the diameter of its lumen, thus creating a natural seal around the distal portion. The sealing effect of the mucosa on the distal portion is reinforced by the coaxial clamping action of the forceps, which contains the dilation of the vas deferens during insertion.

[0028] Preferably, the distal portion is suitable for insertion, at least partially, into the lumen of the vas deferens. The distal portion of the elongated element may include a tapered end to facilitate insertion.

[0029] Advantageously, the distal part of the long element is suitable for being introduced into the vas deferens, preferably in and / or around the lumen, along an axis perpendicular to the F axis.

[0030] Thus, the device's area of ​​action is minimized compared to devices with linear insertion that follow the lumen of the vas deferens over a considerable length. Consequently, the device according to the invention is minimally invasive. Potential inflammation caused by insertion and prolonged placement in the vas deferens is therefore reduced, and the device thus meets the requirements for high tolerance and long lifespan. Furthermore, insertion along an axis perpendicular to the F axis significantly impacts the seal formed by the mucosa around the distal part of the device. This seal then results primarily from forces directed along the F axis. There is therefore little or no radial stress, and leakage is avoided compared to devices of the previous art with linear insertion.

[0031] The elongated element may also have a through-hole capable of allowing flow along axis F when the opening is aligned with the lumen of the vas deferens. Thus, the device according to the invention is both reversible, in the sense that fertility is restored once removed from the individual's body, and also in the sense that fertility is possible while remaining implanted in the subject's body.

[0032] Advantageously, the clamp includes a pair of movable jaws between an open position and a closed position in which the inner surfaces respectively of the first and second jaws each come opposite the outer wall of the vas deferens.

[0033] Preferably, the first and second jaws constitute arched portions suitable for each to come into contact with the outer wall of the vas deferens, the pair of jaws presenting in closed position an elliptical profile in the plane perpendicular to the axis F.

[0034] Quite preferentially, the first and second jaws are made up of arched lamellae.

[0035] Advantageously, the first and second jaws are connected by a flexible hinge. The flexible hinge allows the pair of jaws to move easily between the open and closed positions. In preferred embodiments of the invention, the body of the gripper is formed by the flexible hinge.

[0036] In such variants of the invention in which the elastic hinge connects the jaws or in which the body of the clamp is constituted by the elastic hinge, the number of parts constituting the device is reduced.

[0037] Preferably, the gripper and / or the elastic hinge is configured to allow the pair of jaws to be mobile between an open position corresponding to a passive position in which the gripper is mechanically at rest and a closed position corresponding to an active position in which the gripper is subjected to restoring forces which tend to make it return to the passive open position.

[0038] In advanced variants, the clamp advantageously includes a locking mechanism in the closed position, in which it coaxially grips the outer wall of the vas deferens along an axis of the lumen F, whether the position is actively closed or not. Preferably, the locking mechanism is configured to temporarily immobilize the pair of jaws in the closed position. For example, the locking mechanism could be a pivoting arch. Such a locking mechanism secures the clamp around the vas deferens. Preferably, the elastic hinge incorporates the locking mechanism in the closed position.

[0039] Preferably, in variants where the clamp and / or elastic hinge is configured to allow the pair of jaws to move between a passive open position and an active closed position, the locking means is suitable for maintaining the device in the active closed position and comprises a hooking means such as a tenon, cam, or hook, and a receiving means such as a groove cooperating by overlapping and blocking, by opposing forces, the return to the passive open position. In such variants, the locking means is, for example, of the push-lock type or push-to-close type.

[0040] Regardless of the embodiment, the locking means can be disposed at any suitable location on the clamp, for example at at least one of its arms and / or at a portion of at least one of the jaws.

[0041] In some embodiments of the invention, the clamp is essentially U-shaped, the first and second jaws being arranged respectively at the free end of the first and second branches of the U. Preferably, the elastic hinge is essentially U-shaped, the first and second jaws being arranged respectively at the free end of the first and second branches of the U.

[0042] The body of the clamp and / or the elastic hinge may, for example, consist of at least one curved tab essentially in the shape of a U.

[0043] Of course, any curved shape, essentially U-shaped or C-shaped, is conceivable. Advantageously, the clamp includes at least one actuating means configured to release the locking means when the latter holds the device in the closed position, for example, by the application of a lever force or pressure.

[0044] Preferably, the elastic hinge includes at least one actuating means. Most preferably, the locking means also includes at least one actuating means, which allows for optimization of the device in terms of compactness and / or number of parts. The actuating means may, for example, be a lug, a trigger, or a blind hole, on which the application of a lever force or pressure, manually or with a tool, triggers the opening of the locking means.

[0045] Advantageously, the receiving means of the locking means in the active closed position includes said actuation means.

[0046] In embodiments of the invention in which the clamp and / or hinge is essentially U- or C-shaped, the locking and / or actuating means are preferably located on the inner surface of the clamp, for example, on the inner surface of at least one arm of the U or C, or at the free end located within the internal space of the clamp relative to a jaw. The locking means therefore operates within the internal space defined by the arms of the U or C of the clamp body and / or hinge, and preferably before the pair of jaws. Thus, the risks of unintentional opening or breakage of the locking and / or actuating means, or the risks of unwanted friction with organic tissues, are greatly reduced, since these are protected and contained within this internal space.Advantageously, the receiving means and the attachment means are each disposed at one of the arms of the U-shaped clamp associated with one of the jaws, or at the free end located within the clamp's interior space and relative to the other jaw. Preferably, the receiving means and the attachment means are disposed on the internal surface of the clamp.

[0047] Even more preferably, the receiving means is disposed at the level of the internal surface of one of the branches of the U-shaped hinge associated with one of the jaws and the hooking means is disposed at the level of the free end disposed in the internal space of the clamp and relative to the other jaw.

[0048] In order to control the flow without creating disturbance or blocking it, the device includes a long, thin element whose distal part has a through opening capable of allowing the flow to pass along the F axis, without deflecting it. When the opening is aligned with the light, the device is then in the operating mode called "fertility mode" in which its presence is imperceptible to the individual.

[0049] Also, in order to control the flow without creating disturbance or blocking it, the long element has a diverting tube capable of diverting said flow out of the vas deferens, towards the inside of the individual's body, when an inlet of said diverting tube located at the distal part of said long element is aligned with the lumen of the canal, the device is then in the operating mode called "contraception mode".

[0050] Preferably, the bypass tubing extends between the distal and proximal parts of the long element and has an outlet opening at the level of said proximal part.

[0051] In order to couple the elongated element to the gripper, at least one jaw advantageously possesses one or more of the following characteristics:

[0052] - a bore allowing the insertion of said elongated element,

[0053] - at least one means of locking the long element, possibly with a perforation, such as a keying shoe.

[0054] In preferred embodiments of the invention, the bore passes through the first jaw, and the locking means is disposed on the external surface of the clamp at the level of the first jaw and has a perforation aligned with said bore. In these embodiments, the proximal part of the elongated element preferably forms a head adapted to abut against the locking means when the elongated element is inserted simultaneously through the perforation and the bore. The head may be asymmetrical to indicate, like a misleading device, the method of fertility or contraception.

[0055] Furthermore, in order to facilitate manufacturing and reduce the number of parts of the device, the through opening and the inlet of the diverter tube are advantageously connected, and preferably arranged directly opposite each other.

[0056] The diverting tubing may further include a means of occluding the flow when the through-opening is aligned with the F-axis when the device is operating in fertility mode.

[0057] According to the invention, the device for controlling a flow circulating in the lumen of a vas deferens of a male individual may further comprise an engagement element configured to be coupled to the clamp by a first proximal end, said engagement element having a second free distal end capable of being introduced at least partially into the vas deferens.

[0058] The engagement element can be coupled to the clamp temporarily or coupled to the clamp so as to be permanently fixed to it.

[0059] Preferably, the engagement element is configured to be positioned in the gap of the jaws and to be coupled to the clamp at the bore of the first jaw.

[0060] Quite preferably, the engagement element is a hollow conduit extending from the bore of the first jaw into the gap of the jaws and capable of lining at least the proximal part of the long element when the long element is inserted through the perforation and / or the bore.

[0061] Advantageously, the second free distal end of the engagement element includes a tapered end, facilitating preferential insertion up to the lumen of the vas deferens.

[0062] Finally, in order to facilitate its manufacture and biological tolerance, the device according to the invention is preferably made of polyetheretherketone.

[0078] Detailed description

[0079] An embodiment of the device according to the invention is presented below with reference to figures 1 to 6.

[0080] As illustrated in Figures 1 and 2, the control device 1000 according to the invention manages the flow circulating in the lumen L of a vas deferens C in a male individual. The control device 1000 comprises a clamp 100 configured to coaxially grasp an outer wall of the vas deferens C along an axis F of the lumen L, and a long element 10, adapted to be coupled to the clamp 100, a distal portion 11 of which is adapted to be at least partially inserted into the vas deferens C. The long element 10, shown in various positions in Figures 1 to 4 and 6, comprises a distal portion 11 adapted to be at least partially inserted into the vas deferens C along an axis perpendicular to the axis F and which has dimensions adapted to be inserted at the level of the lumen L so that the mucosa of the vas deferens C serves as a natural seal.

[0081] Thus, the distal part 11 of the elongated element 10 presents:

[0082] - a through-hole 12 shown in Figure 1 where clamp 100 is in the closed position and in Figure 3 where clamp 100 is in the open position, capable of allowing flow along axis F when the opening 12 is aligned with the lumen L in the fertility mode, and

[0083] - a diverting tube 13 shown in Figure 1 and Figure 2 where the clamp 100 is in the closed position and in Figure 4 where the clamp is in the open position, capable of diverting said flow out of the vas deferens C when an inlet 13b, visible in Figure 1 and Figure 4, of said diverting tube 13 is aligned with the lumen L in the contraceptive mode.

[0084] The diverter tube 13 extends between the distal part 11 and the proximal part 14 of the long element 10 and has an outlet opening at the level of said proximal part 14 which forms a head coming against a blocking means 107, 108.

[0085] Furthermore, as illustrated in Figure IB, the through opening 12 and the inlet 13b of the diverter pipe 13 are advantageously connected. In this embodiment, they are also arranged directly opposite each other.

[0086] In order to couple the long element 10 to the clamp 100, the clamp 100 advantageously offers:

[0087] - a locking means 107, 108 in the form of a keying shoe having a perforation 16, disposed at the level of the external surface 101a of the gripper 100 at the level of the first jaw 102, and

[0088] - a through bore 15 aligned with the perforation 16 of the locking means 107, 108, also located at the first jaw 102, so that the elongated element 10 can be inserted simultaneously through the perforation 16 and the bore 15 at the first jaw 102 and coupled to the clamp 100, while being blocked against translation and rotation by means of at least one notch 108. The clamp 100 is configured to coaxially grip the outer wall of the vas deferens C visible in Figure 2. For this purpose, the pair of jaws 102, 103, in the closed position, has an air gap E at the free end of the clamp 100 which is smaller than the diameter of the vas deferens C.The pair of jaws 102, 103 of the clamp 100 is mobile between an open position shown in figures 3 to 6 and a closed position shown in figure 1 and figure 2 in which the inner surfaces respectively of the first 102 and the second 103 jaw each come opposite the outer wall of the vas deferens C. The first 102 and the second 103 jaw constitute arched lamellae adapted to each come opposite the outer wall of the vas deferens C, so that the pair of jaws 102, 103 presents in the closed position an elliptical profile in the plane perpendicular to the axis F.

[0089] In the described embodiment, the body 101 of the gripper 100 is essentially U-shaped and constitutes an elastic hinge connecting the first 102 and the second 103 jaw which are movable between a passive open position in which the gripper is mechanically at rest and an active closed position in which the gripper 100 is subjected to restoring forces which tend to make it return to the passive open position.

[0090] In order to secure and mechanically reinforce the device 1000, the clamp 100 includes a locking means 104, 106 configured to temporarily immobilize the pair of jaws 102, 103 in the closed position gripping the vas deferens C.

[0091] The locking means 104, 106 includes a hooking means 104 in the form of a hook and a receiving means 106 in the form of a rod comprising a groove cooperating by overlapping and blocking, by opposing forces, the return to the open passive position. Also, the clamp 100 includes at least one actuating means 105 in the form of a trigger configured to release the locking means 104, 106 when it holds the device in the closed position, for example, by applying pressure.

[0092] In the currently described variant of the device 1000, the receiving means 106 of the locking means 104, 106 and the actuating means 105 form a single unit, which allows the device to be optimized in terms of compactness and / or number of parts.

[0093] Furthermore, the locking means 104, 106 and the actuation means 105 are arranged at the level of the internal surface 101b, i.e. in the internal space of the clamp 100, with reference to figure 2. Thus, the receiving means 106 is arranged at the level of the internal surface 101b of the first branch of the U-shaped hinge 101 associated with the first jaw 102, and the hooking means 104 is arranged on the internal surface 101b at the level of the free end arranged in the internal space of the clamp 100 relative to the second jaw 103.

[0094] As illustrated in Figure 5 and Figure 6, the control device 1000 may further include an engagement element 17 configured to be coupled to the clamp 100 of the first jaw 102 by a first proximal end 17a, said engagement element 17 having a second free distal end 17b suitable for being introduced at least partially into the vas deferens C. In these preferred variants of the clamp 100 and the control device 1000 according to the invention, the engagement element 17 is configured to be disposed in the gap E of the jaws 102, 103 and to be coupled to the clamp 100 at the bore 15 of the first jaw 102.

[0095] As illustrated in Figure 5, the engagement element 17 can be a solid element such as a rod.

[0096] Alternatively, the engagement element 17 may be a hollow conduit, extending from the bore 15 of the first jaw 102 into the gap E of the jaws 102, 103 and being able to line at least the proximal part 14 of the longitudinal element 10 when the longitudinal element 10 is inserted through the perforation 16 and / or the bore 15.

[0097] Thus, another variant of the engagement element 17 is shown hatched in figure 6 since the engagement element 17 is not directly visible but masked in this position by the first jaw 102.

[0098] Most preferably, and as illustrated in Figure 6, the engagement element 17 may be a hollow conduit, extending coaxially from and in line with the bore 15, and being able to line at least the proximal part 14 of the longitudinal element 10 when the longitudinal element 10 is inserted through the perforation 16 and / or the bore 15. Optionally, the second free distal end 17b of the engagement element 17 may include a tapered end, illustrated non-limitingly in Figure 6.

[0099] Thanks to all these features, the practitioner can easily and quickly implant or modify the operating mode of the 1000 device at the level of the vas deferens C of the male subject.

[0100] During the initial implantation, once the tissues have been dissected to expose the vas deferens (duct C), the practitioner grasps the forceps 100 in the open position and grasps the vas deferens between the jaws 102, 103, applying pressure to the external surface of the forceps 100, for example, to the external surface 101a of the body 101 and / or to the locking means 107, 108 and / or to the second jaw 103, until the locking means 104, 106 are locked in the closed position by overlapping the hook means 104 and the receiver means 106. To complete the implantation procedure, the practitioner then inserts and locks the elongated element 10 in the chosen mode, either for contraception or fertility, by inserting and positioning it appropriately through the perforation 16 and the bore 15 provided in the first jaw. 102 and the blocking means 107, 108. Then simply close the fabrics.If the operating mode needs to be changed, and as often as necessary or desired, the practitioner simply needs to reopen the tissues, remove the elongated element 10 from the forceps 100 (which can remain in the closed position around the vas deferens C), and reinsert it in the new, appropriate position before closing the tissues. The presence of at least one error-proofing device 108 makes this task particularly easy.

[0101] Finally, to proceed with the final extraction of the device 1000, the practitioner simply needs to open the tissues, optionally extract the elongated element 10 from the clamp 100, and perform an appropriate action such as applying pressure to the actuating means 105 to open the locking means 104, 106 and move the clamp 100 from the closed to the open position, thus releasing the vas deferens C, and then close the tissues. It is readily understood that this detailed description relates to a specific embodiment and implementation of the present invention, but that in no way does this description limit the scope of the invention; on the contrary, its purpose is to eliminate any possible ambiguity or misinterpretation of the following claims.

[0102] Thus, it will be understood that the examples of the clamp 100, the elongated element 10, the locking means 107, 108, the locking means 104, 106, and the actuating means 105 presented can vary considerably in their form and structure as required. Similarly, the reference symbols placed in parentheses in the following claims are in no way intended to be limiting; their sole purpose is to improve the intelligibility and understanding of the following claims and the scope of the protection sought.
