Abstract

A contraceptive or occlusion system for restricting and later opening up a reproductive tract or lumen of the vas deferens. The system is adapted to be reversible after implantation, including implantation on, around or within the vas deferens. A method and system to reconnect a severed body lumen, such as the vas deferens, is also provided.

First claim

What is claimed is:

1. A vas deferens occlusion system, comprising:
at least one clamping device with an elongated body including a longitudinal axis, an interior surface sized to receive an outer portion of a vas deferens, and an exterior surface with a radial surface feature extending into the elongated body and about the longitudinal axis; and
at least one securement member operable with the radial surface feature of the at least one clamping device to apply pressure to the outer portion of the vas deferens and occlude an interior lumen of the vas deferens.

2. The system of claim 1 , wherein the elongated body includes a generally tubular shape.

3. The system of claim 1 , wherein the at least one securement member is a suture configured to extend circumferentially around the at least one clamping device.

4. The system of claim 1 , wherein the radial surface feature includes at least one groove.

5. The system of claim 1 , wherein the radial surface feature includes a plurality of grooves spaced apart along the elongated body, the elongated body includes a longitudinal gap, and each groove of the plurality of grooves is divided by the longitudinal gap.

6. A vas deferens occlusion system, comprising:
at least one clamping device including a generally tubular shape adapted to surround an outer portion of a vas deferens, and a plurality of radial grooves extending circumferentially around the generally tubular shape; and
at least one securement member operable with the plurality of radial grooves to facilitate securement of the at least one clamping device around the outer portion of the vas deferens and occlude an interior lumen of the vas deferens.

7. The system of claim 6 , wherein the at least one securement member is a suture.

8. The system of claim 6 , wherein the at least one clamping device includes a living hinge portion.

9. The system of claim 8 , wherein the at least one clamping device includes a longitudinal gap.

10. The system of claim 6 , further including a release mechanism to release the at least one securement member from the plurality of radial grooves.

11. The system of claim 6 , further including an introducing tool to deploy the at least one clamping device around the vas deferens.

12. The system of claim 11 , wherein the introducing tool includes a distal end portion adapted to engage the at least one clamping device.

13. The system of claim 6 , wherein the at least one securement member is constructed at least in part of a shape memory material.

14. A vas deferens occlusion system, comprising:
at least one clamping device including a body with an interior surface defining an interior lumen sized to receive an outer portion of a vas deferens, and an exterior surface defining an exterior surface feature; and
at least one securement member configured to extend circumferentially around the body of the at least one clamping device, the at least one securement member being operable with the exterior surface feature to occlude an interior lumen of the vas deferens by selectively modifying the interior lumen of the at least one clamping device.

15. The system of claim 14 , wherein the at least one clamping device is generally tubular.

16. The system of claim 14 , wherein the at least one securement member is a suture, and the exterior surface feature includes at least one groove formed into an exterior surface of the at least one clamping device to receive at least a portion of the at least one securement member.

17. The system of claim 14 , wherein the securement member is operable to selectively restrict or collapse the interior lumen of the at least one clamping device.

18. The system of claim 14 , wherein the at least one clamping device comprises a longitudinal gap.

19. The system of claim 18 , wherein the at least one clamping device has a living hinge portion.

20. The system of claim 18 , wherein at least one clamping device includes a longitudinal axis, the interior lumen extends along the longitudinal axis, the exterior surface feature defines at least one sidewall perpendicular with the longitudinal axis, and the at least one securement member is operable with a portion of the at least one sidewall.
