1. A device for treating tissue near a valve to modify flow through the valve, comprising:
- an elongate body having a central region and at least two anchoring regions on opposing end portions of the central region, wherein each anchoring region is configured to be anchored to opposing areas of tissue against or adjacent to an annulus of the valve and urge the areas of tissue towards one another; and
the elongate body being further configured for delivery through a catheter to the tissue whereby the elongate body has a first shape during the delivery and a second shape after the delivery.

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.

16. A method for treating tissue near a valve to modify flow through the valve, comprising:
-
providing an elongate body having a central region, a first anchoring region, and a second anchoring region, each of the anchoring regions being attached to opposing end portions of the central region; placing a delivery catheter near the tissue; urging the elongate body through a distal opening defined in the catheter such that the first anchoring region exits the distal opening and attaches to a first area of the tissue against or adjacent to an annulus of the valve; and further urging the elongate body through the distal opening such that the second anchoring region exits the distal opening and attaches to a second area of the tissue against or adjacent to the annulus of the valve such that the first area and the second area are urged towards one another by the elongate body. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25)
