Dual valve prosthesis for transcatheter valve implantation
First Claim
1. A dual heart valve prosthesis comprising:
- a first prosthetic heart valve component for implanting within a first native heart valve having a first stent structure with a first prosthetic heart valve secured therein, wherein when the first prosthetic heart valve component is in an expanded configuration the first stent structure has an upstream segment with a greater expanded diameter than a downstream segment thereof;
a second prosthetic heart valve component for implanting within a second native heart valve having a second stent structure with a second prosthetic heart valve secured therein, wherein when the second prosthetic heart valve component is in an expanded configuration the second stent structure has a downstream segment with a greater expanded diameter than an upstream segment; and
a linkage laterally extending between the first and second stent structures that connects the first and second prosthetic heart valve components together, wherein the linkage laterally extends between a downstream end of the first prosthetic heart valve component and an upstream end of the second prosthetic heart valve, and wherein the linkage is configured for contacting a portion of the heart disposed between the first and second native heart valves when the dual heart valve prosthesis is implanted within the heart.

Abstract
A dual valve prosthesis having first and second prosthetic valve components with a linkage that connects the first and second prosthetic valve components together is disclosed. Each of the first and second prosthetic valve components includes a stent structure with a prosthetic valve secured therein. In a disclosed method, the first and second prosthetic valve components 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. The linkage between the first and second prosthetic valve components is configured to secure the anterior mitral valve leaflet against a wall of the left ventricle when the dual valve prosthesis is implanted within the heart.

6. A method of implanting a dual heart valve prosthesis within a beating heart comprising:
-
introducing a delivery catheter into the left ventricle of the heart, wherein a dual heart valve prosthesis having first and second prosthetic heart valve components connected by a linkage is disposed within a distal portion of the delivery catheter, wherein the linkage laterally extends between a downstream end of the first prosthetic heart valve component and an upstream end of the second prosthetic heart valve component; deploying the first prosthetic heart valve component within the native mitral valve; and deploying the second prosthetic heart valve component within the native aortic valve, such that the linkage connecting the first and second prosthetic heart valve components pushes the anterior leaflet of the native mitral valve against the wall of the left ventricle. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15)

16. A dual heart valve prosthesis comprising:
-
a prosthetic mitral valve component for implanting within the native mitral valve having a stent structure with a prosthetic mitral valve secured therein, wherein the stent structure of the prosthetic mitral valve component in an expanded configuration has an upstream segment with a greater expanded diameter than a downstream segment thereof; a prosthetic aortic valve component for implanting within the native aortic valve having a stent structure with a prosthetic aortic valve secured therein, wherein the stent structure of the prosthetic aortic valve component in an expanded configuration has a downstream segment with a greater expanded diameter than an upstream segment thereof; and a linkage that laterally extends between an outflow end of the prosthetic mitral valve component and an inflow end of the prosthetic aortic valve component to connect the respective stent structures together, wherein the linkage is configured for contacting the anterior leaflet of the native mitral valve within the left ventricle when the dual heart valve prosthesis is implanted within the heart. - View Dependent Claims (17, 18)
