Abstract: Embodiments are provided of an assembly having a prosthetic valve, the prosthetic valve having a radially expandable and compressible annular frame, and a crimping accessory device, and methods for using the assembly in compressing the prosthetic valve. The frame includes an outer surface and an inner surface. A leaflet assembly is supported inside the annular frame. The leaflet assembly includes a plurality of leaflets, each having an inner surface and an outer surface. The crimping accessory device has a plurality of axially-extending fingers. At least a first finger of the plurality of fingers is disposed between the outer surface of a first leaflet of the plurality of leaflets, and at least a second finger of the plurality of fingers is disposed radially-inwardly of the inner surface of the first leaflet.

Abstract: A prosthetic heart valve can include a radially collapsible and expandable annular frame having a plurality of struts defining openings. The prosthetic heart valve can further include a plurality of leaflets that regulate the flow of blood through the frame. The prosthetic heart valve can also include a sealing member mounted on the frame and having an inner layer and an outer layer. At least the outer layer is mounted on the outside of the frame, and the inner layer covers at least the openings in the frame between adjacent cusp portions of adjacent leaflets and the inner layer does not cover one or more openings in the frame at locations facing the outflow surfaces of the leaflets to permit retrograde blood to flow through the one or more uncovered openings in the frame and into space between the outer layer and the frame.
