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 the annular frame has a profile of a flat washer and is attached to the stent structure by a hinge segment, wherein when the dual valve prosthesis is in an expanded configuration the annular frame laterally extends from the stent structure with the hinge segment there between such that the first and second prosthetic valves are laterally offset from each other by the hinge segment.

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.

9. A dual heart valve prosthesis comprising:
-
a first prosthetic valve section including a stent structure with a first prosthetic heart valve secured therein; and a second prosthetic valve section including an annular frame with a second prosthetic heart valve secured therein, the annular frame having a central opening within which the second prosthetic heart valve is secured, wherein when the dual heart valve prosthesis is in an expanded configuration the annular frame forms a circumferential border around the second prosthetic heart valve that extends in a radially outward direction from the central opening of the annular frame with a width that is greater than an overall thickness of the annular frame, and wherein when the dual heart valve prosthesis is in the expanded configuration the first and second prosthetic valve sections are laterally offset from each other by a hinge segment that extends between the stent structure of the first prosthetic valve section and the annular frame of the second prosthetic valve section. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
