Abstract: A transcatheter valve prosthesis includes a stent having a crimped configuration for delivery within a vasculature and an expanded configuration for deployment within a native heart valve. The stent includes at least one axial frame member. The transcatheter valve prosthesis includes at least one outflow marker positioned on the at least one axial frame member. The transcatheter heart valve prosthesis may include inflow markers positioned within the inflow portion of the stent. The transcatheter heart valve prosthesis may include two outflow markers disposed on axial frame members and being circumferentially and longtiduinally offset from each other. The markers are configured to aid in axial and circumferential aligned of the transcatheter heart valve prosthesis within a native heart valve.

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 heart valve prosthesis and a method of assembling the transcatheter heart valve prosthesis are disclosed. The heart valve prosthesis includes a valve-skirt assembly having an inner skirt, a frame, an outer wrap backing and an outer wrap. The method includes: tacking the valve-skirt assembly within the frame; attaching the inner skirt below commissure posts of the frame; attaching commissures of the valve component to the commissure posts; attaching a plurality of outer wrap backings to the inner skirt; attaching the outer wrap backings and the inner skirt to the frame; attaching tissue bumpers to struts in an outflow section of the frame; attaching an outer wrap and the inner skirt to the frame; attaching the outer wrap to the inner skirt proximate inflow edges thereof; and attaching the outer wrap to the inner skirt and to the outer wrap backings proximate respective outflow edges thereof.
