Abstract: A transcatheter valve prosthesis includes a stent and a prosthetic valve. The prosthetic valve is configured to substantially block blood flow in one direction to regulate blood flow through a central lumen of the stent. 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 extending between the inflow portion and the outflow portion. Each axial frame member extends in an axial direction from a crown of the inflow portion to at least a crown of the outflow portion. Each axial frame member has a first end adjacent to the crown of the inflow portion, the first end having a reduced width relative to a width of a length of the axial frame member between the first end and the crown of the outflow portion.

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 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 an inflow portion, an outflow portion, and at least one commissure post positioned at least partially in the outflow portion of the stent. The transcatheter valve prosthesis includes an inflow marker positioned within the inflow portion of the stent, the inflow marker including a first radiopaque material. The transcatheter valve prosthesis includes an outflow marker positioned on the at least one commissure post, the outflow marker including a second radiopaque material. The first radiopaque material and the second radipaque material cause the inflow marker and the outflow marker to be visible relative to the stent in one or more images captured during the installation at the implant location.

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.

Abstract: A transcatheter valve prosthesis includes a stent having a radially compressed configuration for delivery within a vasculature and an expanded configuration for deployment within a native heart valve. The stent includes an inflow portion, an outflow portion, and at least one commissure post extending between the inflow portion and the outflow portion. Inflow and/or outflow markers are positioned on the stent to enable longitudinal and rotational orientation of the stent during the installation at the implant location.
