Methods and devices for occluding an ovarian pathway
First Claim
Patent Images
1. An occluding device for occluding a body lumen comprising:
- a porous polymer plug;
a proximal expandable hoop within a proximal end portion of the plug; and
a distal expandable hoop within a distal end portion of the plug;
wherein the proximal and distal expandable hoops serve to spring the proximal and distal end portions open from a compressed state to an expanded state and provide a proximal and distal anchoring forces for the plug.
