First Claim
1. A device for implantation at a native mitral valve, the native mitral valve having a non-circular annulus and leaflets, comprising:
- 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 extending from the first region, wherein the first region defines an inlet and the second region defines an outlet;
an anchoring member having a longitudinal dimension and including a first portion configured to contact tissue at the non-circular annulus and a second portion having a lateral portion between the first portion and the valve support;
wherein the first portion of the anchoring member is configured to exert a radially outward force against the native valve annulus that prevents the device from moving in an upstream direction;
wherein the second portion of the anchoring member is attached to the valve support while in a low-profile configuration in which the anchoring member and the valve support are configured to be passed through a lumen;
wherein the lateral portion is transverse to the longitudinal dimension and is between the valve support and the first portion of the anchoring member;
wherein the anchoring member and the valve support are configured to move from the low-profile configuration to an expanded configuration in which the first portion of the anchoring member is at least partially adaptable to the non-circular annulus of the native mitral valve and the first region of the valve support is spaced inwardly from the first portion of the anchoring member relative to the longitudinal dimension of the anchoring member such that 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; and
wherein the valve support comprises a first cylinder and the first portion of the anchoring member comprises a second cylinder having a larger diameter than the first cylinder in the expanded configuration.

Abstract
Devices and methods for implantation at a native mitral valve. One embodiment of the device includes a valve support having a first region and a second region, and 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 the first portion of the anchoring member at least partially adapts to the non-circular annulus of the native mitral valve and 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.
