  • Expandable frame for improved hemodynamic performance of transcatheter replacement heart valve
    Patent number: 11877927
    Abstract: A replacement heart valve prosthesis for transcatheter repair of a native valve, the replacement heart valve comprises a valve construct mounted to the exterior surface of an expandable frame. The frame comprises an expandable region near the distal end of the frame, and a cusp region near the proximal region comprising a plurality of valve attachment features. The valve construct may be attached to the valve construct at least at the valve attachment features. The replacement heart valve prosthesis of present disclosure may be a more durable and long-lasting valve that has added benefits by placing valve tissue between the expandable frame and native cardiac tissue.

  • EXTERIORLY MOUNTED TISSUE ON EXPANDABLE FRAME FOR IMPROVED HEMODYNAMIC PERFORMANCE
    Publication number: 20230240841
    Abstract: A replacement heart valve prosthesis for transcatheter repair of a native valve comprises a frame having a distal end, a proximal end, and a length between the distal end and the proximal end, the frame further comprising an exterior surface and an interior surface defining a lumen, the frame expandable from an unexpanded state to an expanded state. The frame further comprises an expandable region near the distal end of the frame and a cusp region near the proximal end of the frame. The cusp region has a plurality of valve attachment features. A valve construct is mounted to the exterior surface of the frame and attached to the frame at least at the valve attachment features.
