Systems and methods for heart valve therapy
First Claim
1. A prosthetic mitral valve system, comprising:
- an anchor assembly configured for coupling with a native mitral valve and comprising a hub member configured for releasable attachment to a delivery catheter; and
a valve assembly coupleable with the anchor assembly and comprising an occluder,wherein, the anchor assembly comprises an expandable anchor frame including the hub member and a first sub-annular support arm extending from the hub member, wherein the first sub-annular support arm extends to a first anchor foot having a first surface configured for engagement with a first sub-annular gutter of the native mitral valve, while the anchor assembly is engaged with the native mitral valve.

Abstract
Prosthetic mitral valves described herein can be deployed using a transcatheter mitral valve delivery system and technique to interface and anchor in cooperation with the anatomical structures of a native mitral valve. This document describes prosthetic heart valve designs that interface with native mitral valve structures to create a fluid seal, thereby minimizing mitral regurgitation and paravalvular leaks. This document also describes prosthetic heart valve designs and techniques to manage blood flow through the left ventricular outflow tract. In addition, this document describes prosthetic heart valve designs and techniques that reduce the risk of interference between the prosthetic valves and chordae tendineae.

6. A method of using a prosthetic mitral valve system, the method comprising:
-
advancing, using a delivery catheter, an anchor assembly of the prosthetic mitral valve system through the vasculature of a patient toward an annulus of a native mitral valve, the anchor assembly comprising a hub member that is releasably attached to the delivery catheter, the anchor assembly defining an interior anchor assembly space in which a valve assembly of the prosthetic mitral valve system is received; interlocking the valve assembly within the interior anchor assembly space; and anchoring the anchor assembly at the native mitral valve, wherein the anchor assembly comprises an expandable anchor frame including the hub member and a first sub-annular support arm extending from the hub member, wherein the first sub-annular support arm extends to a first anchor foot having a first surface that is engaged with a first sub-annular gutter of the native mitral valve while the anchor assembly is anchored at the native mitral valve. - View Dependent Claims (7, 8, 9, 10)

11. A prosthetic mitral valve system, comprising:
-
an anchor assembly configured for coupling with a native mitral valve and comprising a hub member configured for releasable attachment to a delivery catheter; and a valve assembly coupleable with the anchor assembly and comprising an occluder, wherein the anchor assembly includes a proximal end and a distal end and, while the anchor assembly is engaged with the native mitral valve, the hub member is situated at the distal end of the anchor assembly, and wherein the anchor assembly comprises an expandable anchor frame including the hub member and a first sub-annular support arm extending from the hub member, wherein the first sub-annular support arm extends to a first anchor foot having a first surface configured for engagement with a first sub-annular gutter of the native mitral valve. - View Dependent Claims (12, 13, 14, 15)
