Prosthetic heart valve devices, prosthetic mitral valves and associated systems and methods
First Claim
1. A prosthetic heart valve device comprising:
- an expandable inner frame having a first end region and a second end region, the inner frame comprising a generally tubular body portion having an inner surface and an outer surface;
an expandable outer frame having a first end region and a second end region, the outer frame comprising a generally tubular body portion having an inner surface and an outer surface, the outer frame comprising a plurality of interconnected closed cells extending circumferentially around the inner frame, wherein the inner surface of the outer frame is spaced from the outer surface of the inner frame;
a connection structure extending between and connecting the second end region of the outer frame to the second end region of the inner frame, wherein the connection structure is configured to allow movement of the outer frame relative to the inner frame;
a valve member attached to the inner frame;
wherein the first end region of the outer frame is mechanically isolated from the first end region of the inner frame such that the first end region of the inner frame is configured to maintain a cross-sectional shape while the first end region of the outer frame deforms from a first cross-sectional shape into a second cross-sectional shape.

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.
