Contraceptive transcervical fallopian tube occlusion devices and methods
First Claim
1. A device for occluding a reproductive body lumen, comprising:
- an open-walled outer tubular member having a first end, a second end, a lumen extending therein;
an inner member extending through the lumen and surrounded by the open-walled outer tubular member;
a tissue ingrowth supporting member radially disposed between an inner surface of the open-walled outer tubular member and an outer surface of the inner member to support tissue ingrowth to thereby permanently occlude the body lumen; and
a material disposed over the inner member to provide immediate prevention of conception.

Abstract
The invention provides intrafallopian devices and non-surgical methods for their placement to prevent conception. The efficacy of the device is enhanced by forming the structure at least in part from copper or a copper alloy. The device is anchored within the fallopian tube by a lumen-traversing region of the resilient structure which has a helical outer surface, together with a portion of the resilient structure which is biased to form a bent secondary shape, the secondary shape having a larger cross-section than the fallopian tube. The resilient structure is restrained in a straight configuration and transcervically inserted within the fallopian tube, where it is released. Optionally, permanent sterilization is effected by passing a current through the resilient structure to the tubal walls.

6. An intrafallopian contraceptive system, comprising:
-
an open-walled outer member surrounding an inner member, and a tissue ingrowth promoting member radially disposed between an inner surface of the open-walled outer member and an outer surface of the inner member to occlude a fallopian tube for preventing conception; and a material formed over the inner member to provide immediate prevention of conception. - View Dependent Claims (7, 8, 9, 10, 11)

12. A contraceptive device for use in a fallopian tube having a tubal wall, the contraceptive device comprising:
-
a stent-shape tubular retention structure adapted to radially expand to engage the tubal wall of the fallopian; an inner member extending through and surrounded by the stent-shape tubular retention structure; a tissue ingrowth supporting member radially disposed between an inner surface of the stent-shape tubular retention structure and an outer surface of the inner member to cause occlusion of the fallopian tube for preventing conception; and a material formed over the inner member to provide immediate prevention of conception once the contraceptive device has been inserted into the fallopian tube. - View Dependent Claims (13, 14, 15, 16)
