Prosthetic heart valve devices, prosthetic mitral valves and associated systems and methods
First Claim
1. A device for treatment of a native valve of a heart, the device comprising:
- an anchoring member having an annular portion at an upstream region, wherein the annular portion of the anchoring member comprises a first frame configured to press outwardly against an inner surface of a native annulus in an expanded state;
a flange coupled to the annular portion of the anchoring member, wherein the flange extends radially outward with respect to the annular portion of the anchoring member and is configured to engage a supra-annular surface of an atrial side of the native annulus in the expanded state;
an inner valve support disposed in the anchoring member, wherein the inner valve support comprises a second frame having an inflow portion spaced radially inward apart from the annular portion of the anchoring member in the expanded state; and
a prosthetic valve carried by the inner valve support.

Abstract
Prosthetic heart valve devices for percutaneous replacement of native heart valves and associated systems and method are disclosed herein. A prosthetic heart valve device configured in accordance with a particular embodiment of the present technology can include an anchoring member having a first portion configured to engage with tissue on or near the annulus of the native heart valve and to deform in a non-circular shape to conform to the tissue. The device can also include a valve support coupled to a second portion of the anchoring member, configured to support a prosthetic valve and having a cross-sectional shape. In some embodiments, the first portion of the anchoring member is mechanically isolated from the valve support such that the cross-sectional shape of the valve support remains sufficiently stable that the prosthetic valve remains competent when the anchoring member is deformed in the non-circular shape.

5. A device for treatment of a native valve of a heart, the device comprising:
-
an anchoring member having an upstream portion and an atrial retainer configured to extend radially outward from the upstream portion to engage a supra-annular surface, wherein the anchoring member comprises a first frame; a sealing member extending around and radially outward from the upstream portion of the anchoring member, wherein the sealing member is configured to extend over an atrial side of a native annulus, and wherein the anchoring member and the sealing member are configured to prevent paravalvular leaks between the device and native tissue; an inner valve support disposed in the anchoring member, wherein the inner valve support comprises a second frame; and a prosthetic valve carried by the inner valve support.

7. A device for treatment of a native valve of a heart, the device comprising:
-
an anchoring member having an upstream portion, wherein the anchoring member comprises a first frame; a flange extending around the upstream portion of the anchoring member, wherein the flange extends radially outward with respect to the upstream portion of the anchoring member and is configured to extend over an atrial side of a native annulus, and wherein the anchoring member and the flange are configured to prevent paravalvular leaks between the device and native tissue; an inner valve support disposed in the anchoring member, wherein the inner valve support comprises a second frame; and a prosthetic valve carried by the inner valve support; wherein the anchoring member has a first diameter at the upstream portion and a second diameter smaller than the first diameter at a downstream portion of the anchoring member.
