SINGLE SUTURE BIOLOGICAL TISSUE AORTIC STENTLESS VALVE

摘要

A semilunar stentless valve (10) is constructed entirely of biological tissue, and has a plurality of leaflets (11A-11C) that are joined to form an annulus and coapt to form a one-way valve. The leaflets (11A-11C) open fully to minimize obstruction. A narrow rim (12) of tissue overlies commissures (22) where the leaflets (11A-11C) join and around a base (14A-14C) of the valve (10). The valve (10) is of a conical design, flexible, easy to fit and preserves the integrity of the coronary sinuses. The valve (10) can be implanted with a single suture row (46), reducing implant time significantly.
