    Abstract: 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.

    Abstract: 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 a frame, a valvular structure mounted within the frame and comprising a plurality of leaflets, each leaflet comprising tabs on opposite sides of the leaflet and a cusp edge portion, and a plurality of connecting skirts. Each connecting skirt comprises side base portions and a central portion connected to each of the cusp edge portion of a corresponding leaflet and struts of the frame, each connecting skirt further comprising side extension portions that extend away from the cusp edge portion along a length of the frame, where each side extension portion of each connecting skirt extends across struts of the frame, between cusp edge portions of adjacent leaflets and connects to an adjacent side extension portion of an adjacent connecting skirt.

    Abstract: Methods and assemblies for attaching a radiopaque marker to an attachment member of a commissure of a prosthetic valve are disclosed. As one example, a prosthetic heart valve can comprise a frame including struts forming cells of the frame, at least one commissure comprising an attachment member and commissure tabs of two adjacent leaflets coupled thereto, the attachment member arranged across a cell of the frame and attached to struts defining the cell, and a radiopaque marker suspended within the cell and against the attachment member by sutures. The sutures extend from a first portion of the attachment member, through one or more apertures in the marker, and to a second portion of the attachment member, the sutures forming two knots in the second portion that are disposed on opposite sides of the marker such that the sutures form a non-crossing X-pattern through the marker and across the attachment member.
