PROSTHETIC HEART VALVE

Abstract:

The present disclosure is directed to embodiments of catheter-based prosthetic heart valves, and in particular, prosthetic heart valves having sealing members configured to seal the interface between the prosthetic valve and the surrounding tissue of the native annulus in which the prosthetic valve is implanted. In one embodiment, a prosthetic heart valve includes a collapsible and expandable annular frame, a collapsible and expandable valve member mounted within the annular frame, and a collapsible and expandable sealing skirt mounted on the annular frame, wherein the sealing skirt is a pile fabric and can contact tissue surrounding the prosthetic valve when the prosthetic valve is implanted within a native valve annulus.
