A system comprising a prosthetic valve and a delivery catheter

The present disclosure relates to embodiments of catheter-based prosthetic heart valves and, in particular, to prosthetic heart valves having sealing devices configured to seal the interface between the prosthetic valve and the surrounding tissue of the native annulus into which the prosthetic valve is implanted. In one embodiment, a prosthetic heart valve includes an annular sealing member that is positionable in a delivery orientation that extends axially away from an end of the valve when the valve is in a radially compressed state. When the valve expands, the expansion of the frame causes the sealing member to be pulled into an operative orientation that covers a portion of the frame. The present disclosure also discloses novel mechanisms and techniques for mounting valve leaflets into a prosthetic heart valve frame. (Automatic translation with Google Translate, no legal value)
