Abstract: A prosthetic heart valve has a frame including a plurality of strut members, an inflow end, and an outflow end. A leaflet structure is situated at least partially within the frame, and a covering is disposed around an exterior of the frame. The covering includes a cushioning layer, and a first strip member folded over an inflow circumferential edge portion of the cushioning layer to form a first protective portion. A second strip member is folded over an outflow circumferential edge portion of the cushioning layer to form a second protective portion. The first strip member and the second strip member are spaced apart from each other along a longitudinal axis of the prosthetic heart valve.

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 a frame having a plurality of strut members, an inflow end, and an outflow end. The prosthetic heart valve further includes a leaflet structure situated at least partially within the frame, and a covering disposed around the frame. The covering has a first layer and a second layer, wherein the second layer has a plush surface. The first layer is folded over a circumferential edge portion of the second layer to form a protective portion that extends beyond the strut members in a direction along a longitudinal axis of the prosthetic heart valve.

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.
