发明名称 PERCUTANEOUS VALVE REPLACEMENT DEVICES
摘要 A self-expanding valved stent is constructed from a polytetrafluoroethylene (PTFE) covered nitinol or stainless steel wire frame. Anchoring is facilitated by arms emanating from the ventricular end of the device that are designed to atraumatically insinuate themselves around chordae and leaflets and trap them against the expanded stent body. The valve prosthesis includes a partially self-expanding stent having a wire framework defining outer and interior surfaces and anchoring arms. The stent has an unexpanded and an expanded state and anchoring arms having an elbow region and a hook that clamps around mitral tissue of the patient when seated. An elastic fabric/cloth made of, for example, PTFE material, is wrapped circumferentially around the wire framework. A valve having at least one leaflet is fixedly attached to the interior surface of the stent.
