Transcatheter occluding implant
First Claim
1. A transcatheter occluding implant for occluding a vessel lumen, comprising:
- a plug member having a porous outer surface, a compressed configuration allowing for transcatheter delivery to a vessel lumen to be occluded, and an expanded, occluding configuration;
the plug member further including a lumen anchoring portion having a transverse dimension in the expanded configuration which is greater than a transverse dimension of at least a portion of an internal bore of the lumen in which it is to be deployed, the lumen anchoring portion providing a force fit within the lumen to secure the plug therein;
the plug member being formed at least partially of a resilient foam plastics material, the resilient foam plastics material;
assisting in causing the lumen anchoring portion to bear against the internal bore of the lumen when in the expanded configuration, providing support for retaining the anchoring portion in position in the lumen, and having a void content of greater than 70%.

Abstract
A transcatheter occluding implant (50) is used to seal off a vessel lumen such as for arterial and venous embolization, cutting off of supply to tumors, male and female sterilization. There is illustrated a plug member of an open foam plastics material having good hysteresis properties in the form of a shaft 51 carrying annular supports. The implant (50) can be compressed into a very small size and then will expand to contact the internal bore of the vessel to form a force fit within the vessel lumen for secure anchoring of the implant. The open cell foam construction encourages tissue growth and thus further contributes to the stabilization of the implant.
