Zusammenfassung:	A prosthetic heart valve includes a support structure and a valve assembly. The valve assembly includes a cuff and a plurality of leaflets, each of the prosthetic leaflets being composed of a synthetic material. The prosthetic leaflets have a closed condition in which the prosthetic leaflets coapt to restrict blood from flowing in a retrograde direction through the support structure and an open condition in which the prosthetic leaflets allow blood to flow in an antegrade direction through the structure. The synthetic material may be heat set to bias the leaflets to the open or closed condition, or to bias one portion of the leaflet to the open condition and another portion of the leaflet to the closed condition.
