Abstract: An implantable prosthetic valve includes a radially collapsible and expandable annular frame having three commissure attachment posts and four rows of circumferential struts. The rows include a first row, a second row downstream of the first row, a third row downstream of the second row, and a fourth row downstream of the third row and defining an outflow end of the frame. Each row of circumferential struts includes angled struts arranged in a zig-zag pattern. A leaflet structure includes three leaflets forming three commissures, each commissure being connected to one of the commissure attachment posts only at locations along the commissure attachment posts between a first plane that is perpendicular to a longitudinal axis of the frame and intersects crowns of the third row of struts and a second plane that is perpendicular to the longitudinal axis and intersects crowns of the fourth row of struts.

Abstract: A method of crimping an implantable prosthetic valve can include placing protective material over at least a portion of the implantable prosthetic valve. The protective material can be configured to occupy space between open cells of a frame of the implantable prosthetic valve to prevent damage to a leaflet structure of the implantable prosthetic valve. The method can also include crimping the implantable prosthetic valve with the protective material on the implantable prosthetic valve, and removing the protective material from between the frame and the leaflet structure of the implantable prosthetic valve.

The frame can have a plurality of axial struts interconnected by a plurality of circumferential struts. The leaflet structure comprises a plurality of leaflets (e.g., three leaflets arrange to form a tricuspid valve). The leaflet structure has a scalloped lower edge portion secured to the frame. The skirt member can be disposed between the leaflet structure and the frame.

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.
