Abstract
Heart valve prostheses are provided having a self-expanding frame that supports a valve body comprising a plurality of coapting leaflets. The valve body may include a first leaflet, a second leaflet, and a third leaflet, wherein the second leaflet extends between the first leaflet and the third leaflet such that the first and third leaflets are separated from each other by the second leaflet. The leaflets are constructed with four commissure points to reduce the stress and strain applied to the commissure points and to efficiently distribute forces along the leaflets and to the frame. As such, the first and second leaflets may be sewn together to form a first commissure point and a second commissure point, and the second and third leaflets may be sewn together to form a third commissure point and a fourth commissure point, with the four commissure points being sewn to the frame.
