TRANSCATHETER HEART VALVE FOR REPLACING NATURAL MITRAL VALVE
First Claim
1. A prosthetic valve for implantation within a heart, comprising:
- a main body comprising a frame and a one-way valve positioned within the frame; and
a first ventricular anchor coupled to the frame of the main body, the first ventricular anchor comprising a spiral portion configured such that a leaflet of a native valve of the heart may be held securely between the spiral portion and the frame of the main body.

Abstract
Embodiments of prosthetic valves for implantation within a native mitral valve are provided. A prosthetic valve may comprise a radially compressible main body and a one-way valve portion. The prosthetic valve may further comprise one or more ventricular anchors coupled to the main body and disposed outside of the main body. The ventricular anchors may be configured such that a reduced profile of the prosthetic valve is possible. A space may be provided between an outer surface of the main body and the ventricular anchors for receiving native mitral valve leaflets. The prosthetic valve may include an atrial sealing member adapted for placement above the annulus of the mitral valve. Methods and devices for receiving the native mitral valve leaflets between the ventricular anchors and the main body are described.

12. A prosthetic valve for implantation within a native mitral valve, comprising:
-
a main body comprising a tubular frame and a one-way valve positioned within the frame, the main body sized for placement within a native mitral valve; and a first ventricular anchor comprising a first set of struts, wherein the first set of struts are at least partially disconnected from an adjacent portion of the frame such that the first set of struts can expand outwardly away from the frame for positioning behind a posterior leaflet of the native mitral valve. - View Dependent Claims (13, 14)

15. A prosthetic valve for implantation within a heart, comprising:
-
a main body comprising a frame including a first anchor-receiving region; and a first ventricular anchor coupled to the frame and having a shape corresponding to the first anchor-receiving region such that the first ventricular anchor is capable of fitting within the anchor-receiving region of the frame. - View Dependent Claims (16, 17, 18, 19, 20)
