A reversible occlusion device configured for being introduced inside a lumen to selectively occlude it, the reversible occlusion device includes a docking unit configured for being docked in the lumen; the docking unit has an upstream end and a downstream end associated with an upstream portion and a downstream portion of the lumen respectively, and an inner volume extending between the ends; the reversible occlusion device further includes at least one restricting element configured for transitioning between a first, closed position, in which it obstructs passage of material across the volume, and a second, open position, in which it allows passage of material across the volume; in both the closed position and the open position, a peripheral portion of the restricting element is in contact with the docking unit; said restricting element is a membrane with a peripheral portion thicker than its central portion.

Disclosed are methods of delivering an agent to the lumen of the vas deferens under guidance of ultrasound imaging. The methods include vas-occlusive contraception in which the vas deferens is non-surgically isolated and an occlusive substance is percutaneously administered into the lumen of the vas deferens under ultrasound. Also disclosed are methods of reversal of vas-occlusive contraception and methods of delivering an agent to the lumen of the vas deferens. Also disclosed are compositions for use in the methods of the invention.

Methods for removing a biomaterial implant and reversing occlusive effects of the biomaterial implant are described. In particular, methods for performing removal of biomaterial implants without damage to a body lumen where the biomaterial was previously implanted are presented. More specifically, methods of reversing an implant within a vas deferens are described.

The invention relates to a device for controlling a flow circulating in the lumen of a male vas deferens, comprising a clamp configured to coaxially grasp an outer wall of the vas deferens and a long, slender element coupled to the clamp, a distal portion of which is adapted to be at least partially inserted into the vas deferens. Said distal portion has a deflection tube adapted to divert said flow out of the vas deferens when an inlet of said deflection tube is aligned with the lumen. Abstract figure: Fig. 1

Disclosed herein are exemplary medical devices for controlled delivery of material compositions, particularly occlusive, therapeutic, or diagnostic compositions.

A reversible occlusion device configured for being introduced inside a lumen to selectively occlude it, the reversible occlusion device comprising a docking unit configured for being docked in the lumen; the docking unit has, at least when positioned in the lumen, an upstream end associated with an upstream portion of the lumen, and a downstream end associated with a downstream portion of the lumen, and an inner volume extending between a first opening at the upstream end, and a second opening at the downstream end; the reversible occlusion device further comprises at least one restricting element configured for transitioning, at least once, between a first, closed position, in which it obstructs passage of material across the cavity between the first opening and the second opening, and a second, open position, in which it allows passage of material across the cavity between the first opening and the second opening; in both the closed position and the open position, a peripheral portion of the restricting element is in contact with the docking unit.

A system for treating a female patient to promote pregnancy comprising a restriction device adapted to postoperatively restrict and release an oviduct of the patient.

A system for treating a female patient to promote pregnancy, comprising a restriction device configured to restrict and release a patient's fallopian tubes post-operatively.SOLUTION: The system of the present invention allows eggs from an ovary to be retained in the oviduct to avoid pregnancy. A restriction device is placed over the two oviducts to restrict and release the oviducts, thereby retaining the eggs as described above.SELECTED DRAWING: Figure 1A

Disclosed is an implantable tube valve for implanting in a patient, comprising an implantable tube and a valve member mounted inside the tube and pivotable between an open mode and a closed mode. A biasing element preloads the pivot part on the first side of the pivot axis to bistably bias the valve member towards the open or closed mode. The biasing element comprises a compressible sleeve that is axially compressible for providing a preload force on the pivot part. The valve member comprises an operating surface that is mechanically operable by an external actuator device to move the valve member against the preload force between the open and closed mode.

The invention relates to a device for controlling a flow circulating in the lumen of a vas deferens of a male individual, comprising a clamp configured to coaxially grip an outer wall of the vas deferens and an elongate element configured to be coupled to the clamp, a distal portion of which is adapted to be at least partially introduced into the vas deferens. Said distal portion comprises a diversion tube adapted to divert said flow out of the vas deferens when an inlet of said diversion tube is aligned with the lumen.

An apparatus for controlling a flow of fluid in a lumen formed by a tissue wall of a patient's vas deference comprises an implantable constriction device for gently constricting (i.e. without substantially hampering the blood circulation in the tissue wall) at least one portion of the tissue wall to influence the flow in the lumen, and a stimulation device for stimulating the wall portion of the tissue wall. A control device controls the stimulation device to stimulate the wall portion, as the constriction device constricts the wall portion, to cause contraction of the wall portion constricted by the constriction device to further influence the flow in the lumen. The apparatus can be used for restricting or stopping the flow in the lumen, or for actively moving the fluid in the lumen, with a low risk of injuring the vas deference.

Embodiments of the disclosure concern devices comprised of resorbable, shape-memory foam configured to allow for healing at a desired location. In particular embodiments, use of the device at the location utilizes the inherent environment at the location to allow expansion of the device, resulting in an improved fit for the device. In specific cases, the device is a vaginal stent configured for use for pediatric or adolescent populations.

An apparatus for controlling a flow of sperms in a uterine tube formed by a uterine tube wall of a patient's uterine tube comprises an implantable constriction device for gently constricting (i.e. without substantially hampering the blood circulation in the uterine tube wall) at least one portion of the uterine tube wall to influence the flow in the uterine tube, and a stimulation device for stimulating the wall portion of the uterine tube wall. A control device controls the stimulation device to stimulate the wall portion, as the constriction device constricts the wall portion, to cause contraction of the wall portion constricted by the constriction device to further influence the flow in the uterine tube. The apparatus can be used for restricting or stopping the flow in the uterine tube, or for actively moving the fluid in the uterine tube, with a low risk of injuring the uterine tube.
