Dual Valve Prosthesis for Transcatheter Valve Implantation
First Claim
1. A dual valve prosthesis comprising:
- a first prosthetic valve section having a stent structure with a first prosthetic valve secured therein; and
a second prosthetic valve section having an annular frame with a second prosthetic valve secured therein, wherein when the dual valve prosthesis is in an expanded configuration the annular frame laterally extends from the stent structure such that the first and second prosthetic valves are laterally offset from each other.

Abstract
A dual valve prosthesis having first and second prosthetic valve sections is disclosed. The first prosthetic valve section includes a stent structure with a first prosthetic valve secured therein and the second prosthetic valve section includes an annular frame with a second prosthetic valve secured therein. When the dual valve prosthesis is in an expanded configuration, the annular frame extends from the stent structure such that the first and second prosthetic valves are laterally offset from each other. In a method in accordance herewith, the first and second prosthetic valve sections include prosthetic aortic and mitral valves, respectively, and the dual heart valve prosthesis is configured to replace both the native aortic and mitral valves of the heart in a single transcatheter heart valve implantation procedure.

11. A method of implanting a dual valve prosthesis within a beating heart comprising:
-
introducing a delivery catheter transapically into the left ventricle of the heart, wherein a dual heart valve prosthesis disposed within a distal portion of the delivery catheter includes a first prosthetic heart valve section having a stent structure with a first prosthetic valve secured therein and a second prosthetic heart valve section having an annular frame with a second prosthetic valve secured therein, wherein the annular frame laterally extends from the stent structure when the dual valve prosthesis is implanted in the heart; deploying the first prosthetic heart valve section to implant within the native aortic valve such that the first prosthetic valve is a replacement aortic valve; and deploying the second prosthetic heart valve section to implant against the native mitral valve such that the second prosthetic valve is a replacement mitral valve, wherein the annular frame of the second prosthetic heart valve section exerts an apposition force that acts against the heart structure that surrounds the native mitral valve when deployed. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
