GEOMETRIC CONTROL OF BENDING CHARACTER IN PROSTHETIC HEART VALVE LEAFLETS

摘要

Described embodiments are directed toward prosthetic valves having leaflets of particular shapes that control bending character. In accordance with an embodiment, a prosthetic valve has a plurality of leaflets. Each leaflet includes a central region and two side regions on opposite sides of the central region. The central region is defined by a shape of an isosceles triangle defined by two central region sides, the leaflet base and the leaflet free edge, wherein the two central region sides converge from the leaflet base. Each of the two side regions has a shape of a triangle and each is defined by one of the central region sides, one of the leaflet sides, and the leaflet free edge.
