Abstract
A prosthetic heart valve comprises a radially collapsible and expandable annular frame and a leaflet structure comprising three leaflets. Each leaflet has an upper edge portion, a curved lower edge portion and two side flaps, wherein each side flap is connected to an adjacent side flap of another leaflet to form commissures of the leaflet structure, with each commissure being attached to the frame. An annular inner sleeve comprises three U-shaped portions positioned along the curved lower edge portions of the leaflets. An annular outer sleeve extends around are outer surface of the frame, wherein the outer sleeve is made of pericardium. The frame is made of Nitinol and the prosthetic valve can be radially crimped to a radially collapsed configuration inside a sheath for delivery into a patient's body and self-expand to a radially expanded configuration when released from the sheath inside the patient's body.
