    摘要： Devices and methods for crimping a prosthetic heart valve onto a delivery device are described. In some embodiments, valves are crimped over an inflatable balloon and between proximal and distal shoulders mounted on a shaft inside the balloon. Crimping methods can include multiple compression steps with the valve located in different axial positions relative to the crimping jaws at each different step. In some methods, the valve may extend partially outside of the crimping jaws during certain crimping steps, such that the crimping force is only applied to the part of the valve that is inside the jaws. Exemplary crimping devices can include two or more adjacent sets of jaws that close down to different inner diameters, such that different parts of a valve get compressed to different outer diameters at the same time during a single crimping step.

    摘要： 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.

    摘要： Methods and assemblies for attaching leaflets to a frame of a prosthetic heart valve using a connecting skirt are disclosed. As one example, a prosthetic heart valve can include an annular frame comprising a plurality of struts and a valvular structure mounted within the frame and comprising a plurality of leaflets. A cusp edge portion of each leaflet can be connected to the frame by a connecting skirt, where each connecting skirt comprises a central portion and opposing side base portions on opposite sides of the central portion that are connected to each of and disposed between the frame and the cusp edge portion of the leaflet and each connecting skirt can further comprise side extension portions that extend outward from the cusp edge portion of the leaflet and across struts of the frame that are disposed between cusp edge portions of two adjacent leaflets.
