Occlusion devices and methods
First Claim
1. An occlusion system comprising:
- a tube;
an occlusion device at least partially within the tube and deployable from the tube, the occlusion device comprising;
a primary coil having an inner lumen;
an element which supports tissue ingrowth disposed within the inner lumen of the primary coil; and
a wire extending along a substantial length of the primary coil within the inner lumen of the primary coil;
wherein the wire remains within the inner lumen and extending along the substantial length of the primary coil when the occlusion device is deployed from the tube.

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 copper alloy. The device is anchored within the fallopian tube by a lumen-traversing region of the resilient structure which has 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 sterilizations effected by passing a current through there resilisent structure to the tubal walls.

11. A method for occluding a body lumen comprising:
-
advancing a catheter to a target region within an body lumen; and deploying an occlusion device from the catheter at the target region of the body lumen, wherein the occlusion device comprises; a primary coil having an inner lumen; an element which supports tissue ingrowth disposed within the inner lumen of the primary coil; and a wire extending along a substantial length of the primary coil within the inner lumen of the primary coil; wherein the wire remains within the inner lumen and extending along the substantial length of the primary coil when the occlusion device is deployed from the catheter within the body lumen. - View Dependent Claims (12)
