PROSTHESES, SYSTEMS AND METHODS FOR PERCUTANEOUS HEART VALVE REPLACEMENT

摘要

A prostheses for percutaneous heart valve replacement including a stent assembly selectively expandable to an operative position in which the stent assembly is positioned in compressive contact with at least a portion of an interior surface of the native valve annulus; a frame assembly, operatively coupled to a portion of the stent assembly, and that is selectively expandable and that defines a plurality of common upwardly extending commissural posts and a plurality of downwardly extending wing members that at least partially overlie a portion of an exterior surface of the stent assembly; and a biocompatible covering coupled to a portion of the frame assembly and extending to a peripheral edge of the wing members to thereby define a plurality of covered wing members, an upper portion of the biocompatible covering being coupled to a portion of the commissural posts to form an operative valve having a plurality of leaflets.
