Dual valve prosthesis for transcatheter valve implantation
First Claim
Patent Images
1. A dual valve prosthesis for concurrent deployment within first and second adjacent native valves comprising:
- an anchoring frame having an expandable framework;
a first prosthetic valve assembly configured for deployment within the first native valve, the first prosthetic valve assembly being attached to the anchoring frame; and
a second prosthetic valve assembly configured for concurrent deployment within the adjacent second native valve, the second prosthetic valve assembly being attached to the anchoring frame to be laterally separated from the first prosthetic valve assembly by a portion of the anchoring frame, wherein the portion of the anchoring frame is configured to extend between the first and second adjacent native valves when the dual valve prosthesis is deployed, andwherein each of the first and second prosthetic valve assemblies includes a balloon-expandable stent structure with a prosthetic valve secured therein.

Abstract
A dual valve prosthesis having a self-expanding anchoring frame with first and second prosthetic valve assemblies attached to the anchoring frame is disclosed. Each of the first and second prosthetic valve assemblies includes a balloon-expandable stent structure with a prosthetic valve secured therein. In a disclosed method, the first and second prosthetic valve assemblies include prosthetic mitral and aortic valves, respectively, and the dual heart valve prosthesis is configured to replace both the native mitral and aortic valves of the heart in a single transcatheter heart valve implantation procedure.

11. A dual valve prosthesis for concurrent deployment within a mitral valve and an aortic valve comprising:
-
an anchoring frame; a prosthetic mitral valve assembly having a balloon-expandable stent structure attached to the anchoring frame and having a prosthetic mitral valve secured the balloon-expandable stent structure, wherein the balloon-expandable stent structure of the prosthetic mitral valve assembly extends within and is surrounded by the anchoring frame; and a prosthetic aortic valve assembly having a balloon-expandable stent structure attached to the anchoring frame to be laterally offset from the balloon-expandable stent structure of the prosthetic mitral valve assembly and having a prosthetic aortic valve secured therein, wherein the balloon-expandable stent structure of the prosthetic aortic valve assembly is attached to the anchoring frame such that the balloon-expandable stent structure of the prosthetic aortic valve assembly extends away from the anchoring frame, wherein a portion of the prosthetic aortic valve assembly extends within and is surrounded by the anchoring frame. - View Dependent Claims (12, 13, 14, 15)

16. A dual valve prosthesis for deployment within first and second adjacent native valves comprising:
-
an anchoring frame defining laterally separated first and second ports at a first end thereof and a skirt portion at a second end thereof, wherein the skirt portion flares outwardly when the anchoring frame is in an expanded configuration; a first prosthetic valve assembly configured for deployment within the first native valve, the first prosthetic valve assembly having a stent structure with an inflow end attached to the anchoring frame at the first port and having a first prosthetic valve secured therein; and a second prosthetic valve assembly configured for deployment within the adjacent second native valve, the second prosthetic valve assembly having a stent structure with an inflow end attached to the anchoring frame at the second port and having a second prosthetic valve secured therein, wherein respective stent structures of the first and second prosthetic valve assemblies are disposed on the anchoring frame to be laterally separated from each other by a portion of the anchoring frame. - View Dependent Claims (17, 18, 19, 20)
