    Abstract: Assembly methods for installing a leaflet assembly to an expandable frame of a prosthetic heart valve are described. The leaflet assembly comprises a plurality of leaflets coupled together at adjacent tabs, which form respective commissure tab assemblies. The commissure tab assemblies are inserted into corresponding windows of support members of the expandable frame. One or more wedge members are inserted into the commissure tab assembly, e.g., between the adjacent tabs or with the adjacent tabs therebetween, to restrain radial motion of the commissure tab assembly with respect to the window. The window can be a closed window, and the wedge member insertion can be after the commissure tab assembly is inserted into the window. Alternatively, the window can be an open window or channel, and the wedge member insertion can be before the commissure tab assembly is installed in the window.

    Abstract: A method of implanting a prosthetic heart valve within a patient can comprise inserting a distal end portion of a delivery apparatus and a prosthetic heart valve into the patient and advancing the prosthetic heart valve to a deployment location within the heart of the patient and inflating one or more of a plurality of differently-sized balloons in a balloon-assembly on the distal end portion of the delivery apparatus. The prosthetic heart valve can be mounted on the balloon assembly in a crimped state and the inflating of the one or more of the plurality of differently-sized balloons can expand the prosthetic heart valve from the crimped state to a radially expanded state having a non-cylindrical shape.

    Abstract: A prosthetic heart valve includes an annular frame that is radially collapsible and radially expandable, a plurality of leaflets situated within the frame, each leaflet having opposing commissure tab portions on opposite sides of the leaflet, each commissure tab portion paired with an adjacent commissure tab portion of an adjacent leaflet to form at least one commissure, and a plurality of post members mounted on an interior surface of the frame. The at least one commissure includes a commissure attachment assembly including a support member disposed at least partially around the commissure tab portions and the commissure tab portions are folded around the support member. The commissure attachment assembly is secured to a first post member of the plurality of post members such that the commissure tab portions are positioned between the first post member and the support member.

    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.

    Abstract: An implantable prosthetic valve that is radially collapsible to a collapsed configuration and radially expandable to an expanded configuration includes an annular frame including a plurality of angled strut members, and a skirt member secured to the frame. The skirt member includes a plurality of extension portions wrapped around at least one strut member adjacent the extension portions. The prosthetic valve further includes a cord member threaded through at least a portion of the plurality of extension portions to secure the skirt member to the at least one strut member.
