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. |
