## Abstract

Prosthetic heart valves described herein can be deployed using a transcatheter delivery system and technique to interface and anchor in cooperation with the anatomical structures of a native heart valve. Some embodiments of prosthetic valves described herein include an anchor portion that couples to the anatomy near a native valve, and a valve portion that is mateable with the anchor portion. In some such embodiments, the anchor portion and/or the deployment system includes one or more prosthetic elements that temporarily augment or replace the sealing function of the native valve leaflets.

## Claims

### Claim 1

A prosthetic mitral valve system comprising:
an anchor assembly comprising an expandable anchor frame and a prosthetic element attached to the expandable anchor frame, the anchor assembly coupleable with a native mitral valve having an anterior leaflet and a posterior leaflet that cycle between an open valve orientation and a closed valve orientation in which free edges of the anterior and posterior leaflets oppose each other to define a coaptation line,
wherein while the anchor assembly is coupled with the native mitral valve: (i) the anterior and posterior leaflets continue to cycle between the open valve orientation and the closed valve orientation in which the free edges of the anterior and posterior leaflets oppose each other to define the coaptation line, (ii) at least a portion of the prosthetic element is positioned along the coaptation line between the free edges of the anterior and posterior leaflets while the anterior and posterior leaflets are in the closed valve orientation and (iii) the prosthetic element functions as a prosthetic leaflet that cycles between the open valve orientation and the closed valve orientation; and
a valve assembly comprising an expandable valve frame and an occluder attached to the expandable valve frame, the valve assembly selectively coupleable with the anchor assembly.

### Claim 2 (depends on 1)

The prosthetic mitral valve system of claim 1, wherein the prosthetic element is configured to function as a prosthetic posterior leaflet while the anchor assembly is coupled with the native mitral valve.

### Claim 3 (depends on 2)

The prosthetic mitral valve system of claim 2, wherein the prosthetic element comprises a single, continuous member.

### Claim 4 (depends on 2)

The prosthetic mitral valve system of claim 2, wherein the prosthetic element comprises multiple members that are not directly connected to each other.

### Claim 5 (depends on 2)

The prosthetic mitral valve system of claim 2, wherein the prosthetic element comprises three members that are not directly connected to each other.

### Claim 6 (depends on 1)

The prosthetic mitral valve system of claim 1, wherein the prosthetic element comprises flexible, sheet-like material.

### Claim 7 (depends on 1)

The prosthetic mitral valve system of claim 1, wherein the prosthetic element is attached to a portion of the expandable anchor frame that is positioned superior to an annulus of the native mitral valve while the anchor assembly is coupled with the native mitral valve.

### Claim 8 (depends on 7)

The prosthetic mitral valve system of claim 7, further comprising one or more tethers attached to the prosthetic element and to a portion of the expandable anchor frame that is positioned inferior to the annulus of the native mitral valve while the anchor assembly is coupled with the native mitral valve.

### Claim 9 (depends on 1)

The prosthetic mitral valve system of claim 1, wherein the prosthetic element comprises two or more separate members that are attached to the anchor assembly in a fully-circumferential arrangement.

### Claim 10 (depends on 9)

The prosthetic mitral valve system of claim 9, wherein the prosthetic element comprises:
a first prosthetic element configured to function as a prosthetic posterior leaflet while the anchor assembly is coupled with the native mitral valve; and
a second prosthetic element configured to function as a prosthetic anterior leaflet while the anchor assembly is coupled with the native mitral valve.

### Claim 11 (depends on 9)

The prosthetic mitral valve system of claim 9, wherein the prosthetic element comprises three separate prosthetic elements.
