First Claim
Patent Images
1. A method for anchoring an artificial mitral valve in a left atrium of a heart, the method comprising:
- deploying the artificial mitral valve in the left atrium of the heart;
positioning the artificial mitral valve above a natural annulus of a natural mitral valve in the heart; and
shaping an atrial wall to form an artificial annulus to anchor artificial mitral valve.

Abstract
An artificial mitral valve is anchored in the left atrium by placing the valve between the annulus of the natural mitral valve and an artificial annulus. The artificial annulus is formed by inserting a tool into the coronary sinus, and adjusting the tool to force the wall of the left atrium to form an annulus above the artificial valve, this locking it in place and forming a hemostatic seal.

7. A method to replicate a function of a natural mitral valve in a left atrium of a heart, the natural mitral valve about which a coronary sinus of the heart at least partially extends, the method comprising:
-
inserting an artificial mitral valve inside an opening formed by the natural mitral valve in the left atrium of the heart; inserting an elongate member in a flexible state at least partially into the coronary sinus while in the flexible state such that the elongate member at least partially encircles a portion of the artificial mitral valve; and while the elongate member is at least partially in the coronary sinus, transitioning the elongate member from the flexible state to a more rigid state in which the elongate member forms an artificial annulus to physically secure the artificial mitral valve in the opening. - View Dependent Claims (8, 9, 10, 11, 12, 13)

14. A method to replicate a function of a natural mitral valve in a left atrium of a heart, a coronary sinus of the heart forming a path extending at least partially about the natural mitral valve, the method comprising:
-
percutaneously inserting an artificial mitral valve inside an opening formed by the natural mitral valve of the heart; percutaneously inserting an elongate member in a flexible state in the coronary sinus; and percutaneously adjusting a dimension of the elongate member to form an artificial annulus in the coronary sinus to physically secure the artificial mitral valve in the opening without any sutures between the artificial mitral valve and the heart. - View Dependent Claims (15, 16, 17, 18, 19)
