PROSTHETIC HEART VALVE HAVING COMMISSURE SUPPORT ELEMENT

Abstract:

A prosthetic heart valve includes an annular frame including a plurality of angled strut members that is radially collapsible to a collapsed configuration and radially expandable to an expanded configuration. The frame has an inflow end and an outflow end, and includes a leaflet structure positioned within the frame, the leaflet structure comprising a plurality of leaflets arranged to form a plurality of commissures. The frame includes a plurality of commissure support elements, each commissure support element being positioned at one of the commissures. Each of the commissure support elements has a coupling portion coupled to the frame and first and second members coupled to the coupling portion and extending in a direction toward the inflow end of the frame or toward the outflow end of the frame. The leaflets of each commissure are received between the first and second members of the respective commissure support element.
