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.

163. A device for treatment of a native mitral valve of a heart, the device comprising:
-
an anchoring member having an upstream portion, wherein the anchoring member comprises a first frame; a sealing member extending around 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. - View Dependent Claims (164, 165, 166, 167, 168, 169, 170, 171, 172, 173, 174, 175, 176, 177, 188)

178. A device for treatment of a native mitral valve of a heart, the device comprising:
-
an outer frame having a first portion and a second portion downstream of the first portion with respect to blood flow through the native mitral valve; an atrial retainer around a circumference of the first portion of the outer frame, wherein the atrial retainer is configured to extend over an atrial side of a native annulus and engage a supra-annular surface; a sealing member on the outer frame; an inner frame at least partially within the outer frame; and a prosthetic valve carried by the inner frame. - View Dependent Claims (179, 180, 181, 182, 183, 184, 185, 186, 187)
