<p>A transcatheter occluding implant (50) is used to seal off a vessel lumen such as for arterial and venous embolisation, cutting off of supply to tumours, male and female sterilisation. 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 (5). 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 stabilisation of the implant.</p> |
