Prosthetic valve with aligned inner and outer frames
First Claim
1. A prosthetic heart valve configured to transition between a radially compressed configuration and a radially expanded configuration, the prosthetic heart valve comprising:
- an annular outer frame having a lumen extending between an upstream end of the outer frame and a downstream end of the outer frame;
an inner frame situated at least partially within the lumen of the annular outer frame, the inner frame having an upstream end and a downstream end;
at least one connector configured to secure the annular outer frame to the inner frame, the at least one connector being spaced apart from at least one of the downstream end of the annular outer frame or the downstream end of the inner frame; and
a plurality of tissue anchors configured to extend radially outward from at least one of the annular outer frame or the inner frame,wherein the prosthetic heart valve is configured to maintain a first distance between the downstream ends of the annular outer frame and inner frame when the prosthetic heart valve is in the radially compressed configuration and a second distance between the downstream ends of the annular outer frame and inner frame when the prosthetic heart valve is in the radially expanded configuration, the first distance being greater than the second distance.

Abstract
Prosthetic heart valves and methods of use of prosthetic heart valves may be provided. In one implementation, a prosthetic heart valve may include an annular outer frame, an inner frame, and at least one connector configured to secure the outer frame to the inner frame. The connector may be spaced apart from at least one of the downstream end of the outer frame or the downstream end of the inner frame. The prosthetic heart valve may be configured to maintain a greater distance between the downstream ends of the outer and inner frames when the prosthetic heart valve is radially compressed than when the prosthetic heart valve is radially expanded.

15. A prosthetic heart valve configured to transition between a radially compressed configuration and a radially expanded configuration, the prosthetic heart valve comprising:
-
an annular outer frame having a lumen extending between an upstream end of the outer frame and a downstream end of the outer frame; an inner frame situated at least partially within the lumen of the annular outer frame, the inner frame having an upstream end and a downstream end; a plurality of connectors configured to secure the annular outer frame and inner frame against relative axial movement, the plurality of connectors being spaced apart with respect to a circumference of the prosthetic heart valve; and a plurality of tissue anchors configured to extend radially outward from at least one of the annular outer frame or the inner frame, wherein the prosthetic heart valve is configured to maintain a first distance between the downstream ends of the annular outer frame and inner frame when the prosthetic heart valve is in the radially compressed configuration and a second distance between the downstream ends of the annular outer frame and inner frame when the prosthetic heart valve is in the radially expanded configuration, the first distance being greater than the second distance. - View Dependent Claims (16, 17, 18, 19, 20)
