Abstract
Described embodiments are directed toward prosthetic heart valve leaflets of particular shapes that control bending character. In accordance with an embodiment, a prosthetic heart valve comprises a leaflet frame having a generally tubular shape with attached film. The leaflet frame defines a plurality of leaflet windows. The film defines at least one leaflet extending from each of the leaflet windows. Each leaflet attachment zone on the leaflet frame has substantially the shape of an isosceles trapezoid having two leaflet sides, a leaflet base and a leaflet free edge opposite the leaflet base. The two leaflet sides diverge from the leaflet base, wherein the leaflet base is substantially flat.
