Prosthetic heart valve devices, prosthetic mitral valves and associated systems and methods
First Claim
1. A method for replacing a native mitral heart valve having a native annulus and native leaflets with a prosthetic heart valve device having a valve support with an upstream portion and a downstream portion, a valve coupled to the valve support to allow blood to flow from the upstream portion to the downstream portion of the valve support, and an anchoring member with a fixation portion having a first cross-sectional shape in a fully expanded an unbiased condition, a connection structure having an inner portion coupled to the downstream portion of the valve support and an outer portion coupled to the fixation portion, and a transition zone from which the fixation portion extends from the outer portion of the connection structure, the method comprising:
- delivering the prosthetic heart valve in a low-profile delivery configuration into a chamber of the heart through a blood vessel or through a conduit extending through a wall of the heart;
positioning the prosthetic heart valve device near the native mitral valve; and
expanding the prosthetic heart valve device to an expanded configuration in which at least a portion of the connection structure extends in a first direction transverse to a direction of blood flow through the native mitral valve and the fixation portion extends from the transition zone in a second direction different than the first direction, wherein the fixation portion engages inward-facing surface of the native annulus.

Abstract
Devices and methods for implantation at a native mitral valve having a non-circular annulus and leaflets. One embodiment of the device includes a valve support having a first region configured to be attached to a prosthetic valve with a plurality of prosthetic leaflets and a second region, and an anchoring member having a longitudinal dimension with a first portion configured to contact tissue at the non-circular annulus, a second portion configured to be attached to the valve support, and a lateral portion transverse to the longitudinal dimension between the first portion and the second portion. The anchoring member and the valve support are configured to move from a low-profile configuration to an expanded configuration in which a shape of the first region of the valve support is at least partially independent of a shape of the first portion of the anchoring member.
