Abstract: A transcatheter valve prosthesis includes a self-expanding tubular stent component and a prosthetic valve disposed within and secured to the stent component. The tubular stent component has a proximal portion, a distal portion, and an intermediate portion between the proximal and distal portions. In a compressed delivery configuration, the tubular stent component has a generally circular cross-section along its length. In an expanded deployed configuration, the proximal and distal portions have a generally circular cross-section while the intermediate portion of the stent component has a generally triangular cross-section with three vertexes that are configured to project into three commissural points of a native valve when the valve prosthesis is implanted in situ. The generally triangular transverse cross-section of the valve prosthesis is formed by pulling or extending selected or particular struts of the stent component radially outwards and then applying heat to heat-set the stent component in the deployed configuration.

Abstract: A heart valve prosthesis configured for deployment within a native heart valve. The heart valve prosthesis includes a tubular stent and a prosthetic valve component disposed within and secured to the stent. In addition, one or more elements are coupled to a distal end of the stent to position, anchor, and/or seal the prosthesis within the native heart valve. Each element transforms from a compressed configuration in which the elements distally extend from the distal end of the stent to a deployed configuration in which the elements proximally extend from the distal end of the stent. Each element includes at least one U-shaped or V-shaped support arm that bends radially outward and then towards an outer surface of the stent such that it translates more than ninety degrees from the compressed configuration. Each element may include an outer support arm and an inner support arm.
