First Claim
Patent Images
1. An apparatus, comprising:
- a prosthetic heart valve configured to be implanted within a native mitral valve annulus and including a stent body portion and a collar portion coupled to the stent body portion, the collar portion being self-expandable, the stent body portion being tubular and defining an outer circumference,an inflatable sealing member coupled to at least one of the stent body portion or the collar portion and disposed along only a portion of the outer circumference of the stent body portion, the sealing member configured to provide a subvalvular seal to the anterior leaflet of the native mitral valve when the prosthetic heart valve is disposed in the native mitral valve annulus with at least part of the collar portion disposed on an atrial side of the annulus.

Abstract
This invention relates to a pre-configured compressible transcatheter prosthetic cardiovascular valve having an improved anterior leaflet sealing component comprising an inflatable annular sealing device made of a shell of elastomeric material, stabilized tissue or synthetic material, attached to the stent, and wherein during deployment of the valve the shell is filled to form a subvalvular seal. The invention also relates to methods for deploying such a valve for treatment of a patient in need thereof.

9. An apparatus, comprising:
-
a prosthetic heart valve configured to be implanted within a native mitral valve annulus and including a stent body portion and a collar portion coupled to the stent body portion, the collar portion being self-expandable, the prosthetic heart valve further including an inflatable sealing member coupled to at least one of the stent body portion or the collar portion and disposed circumferentially around at least a portion of an outer perimeter of the stent body portion, the sealing member including a first commissural sealing portion, a second commissural sealing portion and an A2 segment sealing portion disposed between the first commissural sealing portion and the second commissural sealing portion, the first commissural sealing portion and the second commissural sealing portion extending outwardly from the stent body portion a greater distance than the A2 segment sealing portion to form a substantially curved outer edge in a top view, the sealing member configured to provide a subvalvular seal to the anterior leaflet of the native mitral valve when the prosthetic heart valve is disposed in the native mitral valve annulus with at least part of the collar portion disposed on an atrial side of the annulus. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)
