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 prosthetic heart valve includes an annular stent having an inflow portion comprising a plurality of rows of angled inflow struts, an outflow portion comprising a row of angled outflow struts, and a transition portion comprising an axial strut and a commissure post, a prosthetic valve including a leaflet structure positioned within the stent and secured to the at least one commissure post, and a tissue bumper configured to reduce abrasion caused by contact by the leaflet structure with the annular stent. The tissue bumper comprises a tissue strip wrapped around at least one angled outflow strut in the row of angled outflow struts, the axial strut, and a portion of a first row of angled struts of the plurality of rows of angled inflow struts.

Abstract: An assembly including a transcatheter valve prosthesis and a leaflet folding accessory configured for use when compressing the transcatheter valve prosthesis into the crimped configuration. The transcatheter valve prosthesis includes a frame and a prosthetic valve component including at least one leaflet disposed within and secured to the frame. The leaflet folding accessory includes a plurality of guide fingers. A leaflet contact portion of each guide finger is configured to be disposed radially within the frame and contact an inner surface of a leaflet of the at least one leaflet. During crimping of the transcatheter valve prosthesis, the plurality of guide fingers remain disposed radially within the frame such that the at least one leaflet preferentially folds around the plurality of guide fingers.
