Paravalvular leak occlusion device for self-expanding heart valves
First Claim
Patent Images
1. A kit for repairing a damaged heart valve comprising:
- a prosthetic heart valve having a collapsible and expandable stent forming cells, the stent having a proximal end and a distal end, the prosthetic heart valve further including a valve assembly disposed in the stent for controlling the flow of blood through the stent; and
an occluder disposed adjacent the proximal end of the stent and longitudinally extending in a lengthwise direction toward the distal end of the stent, the occluder configured to be disposed between the prosthetic heart valve and adjacent body tissue for occluding a gap between the prosthetic heart valve and the adjacent body tissue, the occluder having a first fastener for coupling to the stent and a second fastener for coupling to native heart tissue, the occluder having a delivery, pre-deployment configuration and a final, post-deployment configuration, the occluder in both the pre-deployment and post-deployment configurations including a conformable body having a fillable chamber, a leading end closer to the distal end of the stent and a trailing end closer to the proximal end of the stent, and a port disposed at the trailing end of the body and in fluid communication with the fillable chamber of the body, the body further having an outer coating configured to prevent leakage of a liquid or a gas.

9. A kit for repairing a damaged heart valve comprising:
-
a prosthetic heart valve having a collapsible and expandable stent forming cells, the stent having a proximal end and a distal end, the prosthetic heart valve further including a valve assembly disposed in the stent for controlling the flow of blood through the stent; and an occluder disposed adjacent the proximal end of the stent and longitudinally extending in a lengthwise direction toward the distal end of the stent, the occluder configured to be disposed between the prosthetic heart valve and adjacent body tissue for occluding a gap between the prosthetic heart valve and the adjacent body tissue, the occluder having a delivery, pre-deployment configuration and a final, post-deployment configuration, the occluder in both the pre-deployment and post-deployment configurations including an elongated balloon-like conformable body including a fillable chamber that is closed in the post-deployment configuration and having a leading end closer to distal end of the stent and a trailing end closer to the proximal end of the stent, and a securing feature having a first fastener disposed on the prosthetic heart valve and having a second fastener disposed on and projecting from a surface of the conformable body; the securing feature configured to couple the occluder to the stent. - View Dependent Claims (10, 11, 12, 13)
