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 and techniques to manage blood flow through the left ventricular outflow tract. For example, this document describes prosthetic heart valve designs and techniques that reduce or prevent obstructions of the left ventricular outflow tract that may otherwise result from systolic anterior motion of an anterior leaflet of the native mitral valve.
Claims (14)
1 . A prosthetic mitral valve system comprising:
a valve assembly comprising an expandable valve frame and leaflets attached to the expandable valve frame; and
an anchor assembly comprising an expandable anchor frame, the anchor assembly configured to couple with the expandable valve frame, the expandable anchor frame comprising:
a containment member that is configured to be at least partially disposed behind an anterior leaflet of a native mitral valve when the expandable anchor frame is engaged with the native mitral valve;
a hub member located on the expandable anchor frame;
a plurality of elongate members attached to and extending from the hub member, each elongate member including a sub-annular projection configured to engage tissue proximate to an annulus of the native mitral valve when the expandable anchor frame is in an expanded configuration; and
a cover disposed onto at least a portion of the anchor assembly configured to facilitate coupling between the anchor assembly and the valve assembly.
2 . The prosthetic mitral valve system of claim 1 , wherein the cover is disposed onto an entirety of the anchor assembly.
3 . The prosthetic mitral valve system of claim 1 , wherein the cover is composed of a biocompatible polymer including polyester, silicone, or urethane.
4 . The prosthetic mitral valve system of claim 1 , wherein the cover is attached to the at least one portion of the anchor assembly through the use of an adhesive material.
5 . The prosthetic mitral valve system of claim 4 , wherein the adhesive material is an epoxy.
6 . The prosthetic mitral valve system of claim 1 , wherein the cover is attached to the anchor assembly through the use of wrapping, stitching, or banding the cover onto the anchor assembly.
7 . The prosthetic mitral valve system of claim 1 , wherein the cover is composed of a microporous structure such that the cover is configured to enhance tissue ingrowth with the anchor assembly.
8 . The prosthetic mitral valve system of claim 1 , wherein the cover comprises a hydrophilic coating disposed thereon.
