Abstract

Heart valve prostheses are provided having a self-expanding frame that supports a valve body comprising a skirt and a plurality of coapting leaflets. The leaflets are constructed with four commissure points to reduce the stress and strain applied to the commissure points and to efficiently distribute and transmit forces along the leaflets and to the frame.
