Abstract

A device and method of using the device for contraception or sterilization and particularly for reversible contraception by occluding a reproductive lumen to prevent the passage of reproductive cells through the lumen for a desired period of time until the patient wishes to become fertile again and then be reopened. The occluding member preferably comprises a tubular framework formed from a shape memory material configured to be implanted in a reproductive lumen. The occluding member is implanted within a body lumen, secured to the wall of the reproductive lumen and then collapsed to collapse the wall and occlude the lumen. Alternatively, the occluding member may be collapsed upon a solid plug. The closure of the reproductive lumen may be reversed by introducing a balloon catheter and by a series of inflations of the balloon reexpanding the collapsed occluding member or by removing the plug. The occluding member and the plug may be configured to facilitate endothelialization, to provoke an inflammatory responses or to deliver a drug.

Claims

1. A system for occluding a body lumen, comprising:

a coated or seeded tubular member including an open framework to spur ingrowth of tissue cells into the tubular member, the tubular member characterized by an axial length;

a solid rod-shaped occlusive plug member comprising silicone extending the entire axial length inside the tubular member; and

a catheter configured to deliver RF energy within the body lumen and outward from the catheter.

2. The system of claim 1 wherein the tubular member is configured to provoke an inflammatory response in the body lumen.

3. The system of claim 2 wherein the inflammatory response is provoked by radioactive material.

4. The system of claim 1 wherein the tubular member is formed of a shape-memory material that is expandable from a first configuration to a second larger configuration that secures the tubular member in the second configuration to a wall portion of the body lumen.
