Abstract

A heart valve prosthesis includes a molded body and a plurality of leaflets. Each leaflet includes a free margin having opposite ends and a mid-point. The opposite ends are attached to a peripheral portion of the valve. Each free margin is adjacent each other free margin to form a natural-state non-uniform gap therebetween. The gap has a maximized width adjacent the mid-point of each leaflet. Each free margin is scalloped to form a peak at the opposite ends and a mid-point peak between the opposite ends. Each peak is substantially the same height above the base.
