Abstract

There is provided a method for controlling a flow of fluid in the vas deferens in order to obtain a controlled male contraception. The method comprises 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 vas deferens, and stimulating the constricted wall portion to cause contraction of the wall portion to further influence the flow in the vas deferens. The method can be used for restricting or stopping the flow in the vas deferens, or for actively moving the fluid in the vas deferens, with a low risk of injuring the organ.

First claim

What is claimed is:

1. A method for controlling a flow of sperms in a vas deferens of a male patient, comprising the steps of:
a) gently constricting by a constriction device the tissue wall portion of vas deferens to influence the flow in the vas deferens, and
b) stimulating by a stimulation device the constricted wall portion of vas deferens to cause contraction of the wall portion to further influence the flow in the vas deferens, the method further comprising providing an external source of energy outside the patient's body, controlling the external source of energy from outside the patient's body to release wireless energy, and using the released wireless energy for operating at least one of the construction and stimulation devices.

2. The method according to claim 1 , wherein the wall portion is constricted, so that the flow in the vas deferens at least is restricted and the constricted wall portion is stimulated to at least further restrict the flow in the vas deferens.

3. The method according to claim 2 , wherein the vas deferens wall portion is constricted to a constricted state, in which the blood circulation in the constricted wall portion is substantially unrestricted and the flow in the vas deferens is at least restricted, and the constricted wall portion is stimulated when it is in the constricted state to at least further restrict the flow in the vas deferens.

4. The method according to claim 2 , wherein step (a) is performed by constricting the wall portion, so that the flow in the vas deferens is restricted but not stopped, and step (b) is performed by stimulating the constricted wall portion to cause contraction thereof, so that the flow in the vas deferens is further restricted but not stopped.

5. The method according to claim 4 , further comprising sensing a physical parameter of the patient and adjusting the intensity of the stimulation of the wall portion in response to the sensed parameter.

6. The method according to claim 4 , further comprising (c) ceaseing stimulating the wall portion to increase the flow in the vas deferens, (d) releasing the wall portion to restore the flow of sperms in the vas deferens.

7. The method according to claim 2 , wherein step (a) is performed by constricting the wall portion, so that the flow in the vas deferens is restricted but not stopped, and step (b) is performed by stimulating the constricted wall portion to cause contraction thereof, so that the flow in the vas deferens is stopped.

8. The method according to claim 7 , further comprising (c) ceaseing stimulating the wall portion to allow flow in the vas deferens, (d) releasing the wall portion to restore the flow in the vas deferens.

9. The method according to claim 2 , wherein step (a) is performed by constricting the wall portion, so that the flow in the vas deferens is substantially stopped, and step (b) is performed by stimulating the constricted wall portion to cause contraction thereof, so that the flow in the vas deferens is completely stopped.

10. The method according to claim 9 , further comprising (c) ceaseing stimulating the wall portion to allow flow in the vas deferens, and (d) releasing the wall portion to restore the flow in the vas deferens.

11. The method according to claim 9 , further comprising sensing a physical parameter of the patient and adjusting the intensity of the stimulation of the vas deferens wall portion in response to the sensed parameter, wherein the intensity of the stimulation of the wall portion is increased so that the flow in the vas deferens remains stopped when a pressure increase occurs in the vas deferens, wherein the physical parameter of the patient's relates to the pressure in the vas deferens and the stimulation of the wall portion is controlled in response to the sensed parameter, and wherein the physical parameter is a pressure in the patient's body.

12. The method according to claim 1 , wherein the wall portion is stimulated while the constriction of the wall portion is changed.

13. The method according to claim 1 , wherein the constriction of the wall portion is calibrated by stimulating the wall portion while adjusting the constriction of the wall portion until the desired restriction of the flow in the vas deferens is obtained.

14. The method according to claim 1 , wherein step (b) is not performed while step (a) is performed.

15. The method according to claim 1 , wherein step (a) is performed by constricting the wall portion, so that the flow in the vas deferens is stopped.

16. The method according to claim 15 , further comprising (d) releasing the wall portion to restore the flow in the vas deferens.

17. The method according to claim 15 , wherein step (b) is performed by stimulating the constricted wall portion to cause contraction thereof, so that the flow in the vas deferens remains stopped when a pressure increase occurs in the vas deferens, further comprising sensing a physical parameter of the patient that relates to the pressure in the vas deferens, and controlling the stimulation of the wall portion in response to the sensed parameter, wherein the physical parameter is a pressure in the patient's body.

18. The method according to claim 1 , wherein steps (a) and (b) are co-operated to move the fluid and/or other bodily matter in the vas deferens.

19. The method according to claim 18 , wherein step (a) is performed by constricting the wall portion to restrict the flow in the vas deferens, and step (b) is performed by progressively stimulating the constricted wall portion to cause progressive contraction of the wall portion to move the fluid and/or other bodily matter in the vas deferens, and, wherein the constricted wall portion is progressively stimulated in the downstream or upstream direction of the vas deferens.

20. The method according to claim 18 , wherein step (a) is performed by constricting the wall portion to restrict the flow in the vas deferens, and step (b) is performed by stimulating the constricted wall portion to close the vas deferens either at an upstream end or a downstream end of the constricted wall portion, further comprising (c) increasing the constriction of the wall portion to move the fluid and/or other bodily matter in the vas deferens.

21. The method according to claim 18 , wherein step (a) is performed by varyingly constricting the wall portion to vary the flow in the vas deferens, and step (b) is performed by progressively stimulating the constricted wall portion to cause progressive contraction of the wall portion to move the fluid and/or other bodily matter in the vas deferens, wherein the constricted wall portion is progressively stimulated in the downstream or upstream direction of the vas deferens.

22. The method according to claim 18 , wherein step (a) is performed by varyingly constricting different areas of the wall portion to cause progressive constriction of the wall portion in the downstream or upstream direction of the vas deferens.

23. The method according to claim 22 , wherein the constricted wall portion is progressively stimulated to cause progressive contraction thereof in harmony with the progressive constriction of the wall portion.

24. The method according to claim 22 , further comprising providing at least one elongated constriction element extending along the wall portion, and controlling the elongated constriction element to progressively constrict the wall portion in the downstream or upstream direction of the vas deferens, wherein the
