Abstract: A system can include a delivery catheter comprising a balloon and an implantable prosthetic heart valve. The prosthetic valve can have a plastically expandable and compressible unitary frame comprising a plurality of circumferentially extending rows of angled struts, including first, second, and third rows of angled struts forming rows of diamond-shaped cells, and a valvular structure comprising a plurality of leaflets. A cusp edge portion of each leaflet is connected to the frame by a skirt that is disposed between the frame and the cusp edge portions, the skirt being sutured to selected struts of the frame along diagonal paths extending from an inflow end portion toward an outflow end portion. Each diagonal path along which the skirt is sutured to the frame extends along the first, second, and third rows of angled struts.

Abstract: A prosthetic heart valve includes an annular frame including a plurality of strut members that is radially collapsible and expandable. A leaflet structure is situated within the frame, and includes a plurality of leaflets having opposing commissure tab portions on opposite sides of the leaflet. Each commissure tab portion is paired with an adjacent commissure tab portion of an adjacent leaflet to form one or more commissures. A commissure support element is positioned at each of the commissures, and comprise a first member and a second member that are separable from each other and configured to receive leaflets therebetween. The first and second members are detached from the frame and spaced radially inwardly from the frame such that the members contact the leaflets radially inward from the frame and limit movement of the leaflets so that they articulate at a location that is spaced radially inwardly from the frame.

Abstract: A prosthetic heart valve can include a radially expandable and compressible frame having an inflow end portion and an outflow end portion, the frame comprising a plurality of struts defining openings between them. The prosthetic valve can further include a valvular structure comprising a plurality of leaflets, each leaflet comprising a main body, opposing tabs on opposite sides of the main body, a coaptation edge portion, and a cusp edge portion. Each tab can be paired with an adjacent tab of an adjacent leaflet to form a plurality of commissures that are fixed relative to the frame, and each leaflet can have opposing edge portions between the opposing tabs and the cusp edge portion that are unattached to the frame, each unattached edge portion defining a gap that extends radially into the main body of the leaflet.

Abstract: In one embodiment, a prosthetic valve can comprise a radially expandable and compressible frame, which can include a plurality of struts which are pivotally joined together without requiring individual rivets. In some embodiments, the struts are interwoven, and can be joined using integral hinges formed in the struts, such as by performing alternate cuts on the struts, bending the struts to form stopper tabs adjacent to joints and/or drilling holes in the struts to facilitate interconnecting struts at joints, or otherwise forming integral hinges and corresponding holes at junction points between the struts. In another embodiment, the frame comprises a plurality of inner struts and outer struts which are connected by a plurality of chains of interconnected rivets, avoiding the need to provide individual rivets at each junction between struts. In still another embodiment, separate hinges or flanged rivets are provided to interconnect the struts.

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: A system can include a delivery catheter comprising a balloon and an implantable prosthetic heart valve. The prosthetic valve can have a plastically expandable and compressible unitary frame comprising first, second, and third rows of angled struts that define two circumferentially extending rows of diamond-shaped cells that extend continuously around the frame, and a valvular structure comprising a plurality of leaflets. A cusp edge portion of each leaflet is connected to the frame by a skirt that is connected to and disposed between the frame and the cusp edge portions of the leaflets, the skirt being connected to consecutive struts in the first, second, and third rows of struts with sutures. The compressed prosthetic heart valve can be mounted around the balloon and radially expanded to the expanded configuration with the balloon inside a patient's body.
