摘要： Assembly methods for installing a valvular structure to an expandable annular frame of a prosthetic heart valve are described. The valvular structure has a multiple leaflets, each with a pair of tabs. Each tab of the leaflet has upper and lower portions. Commissures formed by paired tabs of adjacent leaflets are coupled to corresponding commissure windows to support the valvular structure within the frame. Each commissure window has upper and lower openings separated from each other by a crossbar and may have an H-shape. The upper and lower tab portions extend through the upper and lower openings, respectively, of the corresponding commissure window. One or more wedge members coupled to the tab portions can prevent the leaflet tab from passing back through the commissure window, thereby retaining the valvular structure to the annular frame.

摘要： Valve repair devices are disclosed herein. The valve repair devices are configured to reduce or inhibit regurgitant blood flow through a native heart valve. The valve repair devices are configured to be positioned within the native heart valve orifice and attached to the native heart valve. The device can be connected to leaflets of the native valve by a variety of different types of paddles.

摘要： Expandable sheaths are disclosed herein. In some aspects, the sheath comprises at least one plurality of struts arranged to form an expandable cylindrical frame such that the formed frame is kink resistant. The disclosed frames are configured to expand from a first diameter d1 in an unexpanded position to a second diameter d2 an expanded position upon passage of a medical device, while maintaining the kink resistance. Also disclosed are methods of making the same.
