Abstract

A device for repairing a native heart valve includes a reinforcing structure configured to couple to a portion of the native heart valve to remodel a geometry of the native heart valve, and at least one supporting member connected to the reinforcing structure.

Claims

1. A device for repairing a native heart valve, comprising:

an inflatable, collapsible and expandable, and continuously toroidal-shaped body having an inner perimeter and an outer perimeter, the inner perimeter defining an unobstructed opening and the outer perimeter being capable of matching a perimeter of the native heart valve, the body being configured to couple to at least a portion of the annulus of the native heart valve to remodel a geometry of the native heart valve;

a plurality of flexible coils extending from the body for coupling the body to the native heart valve; and

a plurality of hooks extending from an underside of the body for coupling the body to native valve leaflets.

2. The device of claim 1, wherein the body comprises a rigid brace configured to couple to a fibrous ring of the native heart valve.

3. The device of claim 1, wherein the body further includes an inflation port capable of receiving an inflation medium.

4. The device of claim 3, wherein the inflation medium is selected from one of saline, a gas, a polymeric material, a nitinol foam, or a gel.

5. The device of claim 1, wherein the inner perimeter and the outer perimeter are concentric.

6. The device of claim 1, wherein the plurality of flexible coils extend from the underside of the body.
