PROSTHETIC HEART VALVE DEVICES, PROSTHETIC MITRAL VALVES AND ASSOCIATED SYSTEMS AND METHODS
First Claim
1. A prosthetic heart valve device comprising:
- a valve support;
a prosthetic valve having a plurality of leaflets disposed within the valve support;
an anchoring member having an upstream portion, a downstream portion, and a frame spaced radially outward from and encircling at least a portion of the valve support, the frame having an engagement surface facing laterally outward when the prosthetic heart valve device is in an expanded state, wherein the engagement surface is configured to exert a radially outward force against an inner surface of a native annulus facing the valve support to secure the heart valve device against ventricular systole forces, and wherein the upstream and downstream portion are defined relative to a direction of blood flow through the native annulus; and
an extension member extending radially outward from the upstream portion of the anchoring member.

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 an upstream 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 mechanically isolated valve support coupled to the anchoring member and configured to support a prosthetic valve. The device can further include an atrial extension member extending radially outward from the upstream portion of the anchoring member and which is deformable without substantially deforming the anchoring member. In some embodiments, the upstream portion of the anchoring member and the extension member may be deformed while the valve support remains sufficiently stable.

10. A prosthetic heart valve device comprising:
-
a valve support configured to carry a prosthetic valve; an anchoring member having an upstream portion, a downstream portion, and a frame, the frame comprising a generally tubular body having a plurality of interconnected closed cells extending circumferentially around the valve support, wherein an inner surface of the frame is spaced apart from the valve support, wherein an outer surface of the frame is configured to press against an inward-facing surface of ta native annulus; and an extension member extending laterally outward from the upstream portion of the anchoring member and configured to engage tissue upstream of the native annulus. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
