Abstract: A transcatheter valve prosthesis includes a stent and a prosthetic valve. The stent includes an inflow portion, an outflow portion, and a transition portion extending between the inflow portion and the outflow portion. The transition portion includes a plurality of axial frame members, and three of the plurality of the axial frame members are commissure posts. At least two of the plurality of the axial frame members are commissure posts having a first end connected to a crown of the inflow portion and an unattached second end disposed within the outflow portion such that a pair of struts of the outflow portion intersect each commissure post at a mid-portion thereof. The prosthetic valve is configured to substantially block blood flow in one direction to regulate blood flow through a central lumen of the stent.

Abstract: A transcatheter valve prosthesis includes a stent and a prosthetic valve disposed within the stent. The stent is balloon expandable and includes an inflow portion, an outflow portion, and a transition portion extending between the inflow portion and the outflow portion. A diameter of an inflow end of the transcatheter valve prosthesis is greater than a diameter of an outflow end of the transcatheter valve prosthesis. The transcatheter valve prosthesis has a tapered profile along an entire height thereof when in the stent is in the expanded configuration. The inflow end of the transcatheter valve prosthesis is configured to sit within and contact an aortic annulus of the native aortic valve and the outflow end of the transcatheter valve prosthesis being configured to float within an ascending aorta without contacting the ascending aorta due to the tapered profile of the transcatheter valve prosthesis.

Abstract: A transcatheter valve prosthesis includes a frame and a prosthetic valve coupled to the frame. In a radially compressed configuration, the frame is a single layer tube. In a radially expanded configuration, the frame comprises an outer structure and an inner structure, wherein the prosthetic valve attached to the inner structure, and wherein the outer structure surrounds the inner structure and is spaced from the inner structure by a gap.

Abstract: A prosthetic valve component is disclosed for a valve prosthesis. The valve component includes valve leaflets configured to be operably coupled within a frame of the valve prosthesis, wherein each valve leaflet is shaped and sized to achieve a target pinwheeling score PS. The target pinwheeling score correlates to full contact being made between free edges of the valve leaflets, when the valve leaflets are operably coupled within the frame of the valve prosthesis, such that no central opening and little to no overlap occurs between the valve leaflets.

Abstract: A transcatheter valve prosthesis includes a balloon expandable stent and a prosthetic valve. An inflow portion of the stent includes a plurality of crowns and a plurality of struts with each crown being formed between a pair of opposing struts. Endmost inflow side openings and endmost inflow crowns are formed at the inflow end of the stent and the inflow end of the stent has a total of twelve endmost inflow crowns. An outflow portion of the stent includes a plurality of crowns and a plurality of struts with each crown being formed between a pair of opposing struts. Endmost outflow crowns are formed at the outflow end of the stent and the outflow end of the stent has a total of six endmost outflow crowns. The prosthetic valve is disposed within and secured to the stent.
