Abstract

The present invention relates to a male contraception apparatus for obtaining temporary sterility of a male mammalian individual. The apparatus comprises an implantable restriction device adapted to restrict vas deference in the region downstream the ampulla during a controlled period in order to preventing sperms to reach the urethra. Further, the apparatus comprises a control device for controlling the operation of the restriction device.

Claims

1. A male contraception apparatus for obtaining temporary sterility of a male mammalian individual comprising:

an implantable restriction device adapted to restrict vas deference in the region downstream the ampulla during a controlled period, said device thereby being capable of preventing sperms to reach the urethra, and

a control device for controlling the operation of the restriction device.

2. The apparatus according to claim 1, wherein the restriction device comprises a constriction device for constricting at least one portion of a tissue wall of vas deference downstream the ampulla to stop the flow in the vas deference.

3. The apparatus according to claim 2, wherein the constriction device is adjustable, and further comprising an operation device for operating the adjustable constriction device to change the constriction of a wall portion of vas deference.

4. The apparatus according to claim 3, wherein the operation device mechanically operates the constriction device.

5. The apparatus according to claim 3, wherein the operation device hydraulically operates the constriction device.

6. The apparatus according to claim 3, wherein the operation device operates the restriction device in a non-magnetic and/or non-manual manner.

7. The apparatus according to claim 3 wherein the operation device comprises an electrically powered operation device.

8. The apparatus according to claim 7 wherein the operation device comprises a motor.

9. The apparatus according to claim 8 wherein the operation device comprises a servo system.

10. The apparatus according to claim 4, wherein the constriction device comprises at least two elongated clamping elements extending along the organ in the direction of flow in the patient'"'"'s vas deference on different sides of the organ, and the operation device operates the clamping elements to clamp the wall portion between the clamping elements to constrict the wall portion.

11. The apparatus according to claim 5, wherein the operation device comprises hydraulic means for hydraulically adjusting the constriction device and a reverse servo operatively connected to the hydraulic means.

12. The apparatus according to claim 5, wherein the restriction device comprises a non-inflatable mechanical constriction device and the operation device comprises hydraulic means that hydraulically adjusts the mechanical constriction device.

13. The apparatus according to claim 1, wherein the restriction device comprises a stimulation device for stimulating a wall portion of the tissue wall of vas deference in the region downstream the ampulla to contract said wall portion to influence the flow in vas deference.

14. The apparatus according to claim 13, wherein the control device controls the stimulation device to adjust the intensity of the stimulation of the wall portion in response to a sensed functional parameter of the apparatus or a sensed physical parameter of the patient.

15. The apparatus according to claim 13, wherein the control device controls the stimulation device in a first mode to stimulate the constricted wall portion to further restrict but not stop the flow in the vas deference and controls the stimulation device in a second mode to cease the stimulation of the wall portion to increase the flow in the vas deference.

16. The apparatus according to claim 13, wherein the control device in the second mode controls the stimulation device to cease the stimulation of the wall to restore the flow in the vas deference.

17. The apparatus according to claim 13, wherein said control device controls said stimulation device to stimulate the constricted wall portion to cause contraction thereof, such that the flow in the vas deference is stopped.

18. The apparatus according to claim 13, wherein the control device controls the stimulation device in a first mode to stimulate the constricted wall portion to stop the flow in the vas deference and controls the stimulation device in a second mode to cease the stimulation of the wall portion to allow flow in the vas deference.

19. The apparatus according to claim 18, wherein the control device in the second mode controls the stimulation device to cease the stimulation of the wall portion and controls the constriction device to release the wall portion to restore the flow in the vas deference.

20. The apparatus according to claim 18, wherein the control device controls the stimulation device to adjust the intensity of the stimulation of the wall portion in response to a sensed physical parameter of the patient.
