1. A medical apparatus for remodeling a mitral valve annulus, comprising:
- an elongate body having a proximal end region and a distal end region, the elongate body having a first configuration for delivery via a catheter to a location adjacent a mitral valve annulus, the elongate body having a second configuration for reshaping the mitral valve annulus to improve coaption of the mitral valve leaflets; and
a forming element attached to the elongate body for manipulating the elongate body from the first configuration to the second configuration;
wherein the proximal and distal end regions of the elongate body are configured to be anchored to opposing regions of tissue adjacent the mitral valve annulus and wherein the elongate body urges the opposing regions of tissue together when manipulated to the second configuration.

Abstract
A device for treatment of mitral annulus dilatation comprises an elongate body having two states. In a first of these states the elongate body is insertable into the coronary sinus and has a shape adapting to the shape of the coronary sinus. When positioned in the coronary sinus, the elongate body is transferable to the second state assuming a reduced radius of curvature, whereby the radius of curvature of the coronary sinus and the radius of curvature as well as the circumference of the mitral annulus is reduced.

11. A medical apparatus for remodeling a mitral valve annulus, comprising:
-
an elongate body having a first anchor and a second anchor, the elongate body having a first configuration for delivery through a catheter and a second configuration for reshaping the mitral valve annulus to improve coaption of the mitral valve leaflets; wherein the first and second anchors of the elongate body are configured to be fixed to opposing regions of tissue adjacent the mitral valve annulus and wherein the elongate body urges the opposing regions of tissue together when in the second configuration. - View Dependent Claims (12, 14)

13. A medical apparatus for remodeling a mitral valve annulus, comprising an elongate body having a substantially fixed length, the elongate body being sized for insertion at least partially into a coronary sinus, wherein the elongate body is configured to change curvature after insertion into the coronary sinus for exerting a compressive force on the mitral valve annulus.
