## Abstract

A mitral valve therapy device and method treats dilated cardiomyopathy. The device is configured to be placed in the coronary sinus of a heart adjacent to the mitral valve annulus. The device includes a force distributor that distributes an applied force along a pericardial wall of the coronary sinus, and a force applier that applies the applied force to one or more discrete portions of a wall of the coronary sinus adjacent to the mitral valve annulus to reshape the mitral valve annulus in a localized manner.

## Claims

### Claim 1

A device that effects the condition of a mitral valve annulus of a heart comprising an elongated member dimensioned to be placed in the coronary sinus of the heart adjacent the mitral valve annulus, the elongated member having a relatively low resistance to flexure in a first direction and a relatively high resistance to flexure in a second direction, wherein the first and second directions lie in the same plane.

### Claim 2 (depends on 1)

The device of claim 1 wherein the elongated member includes a first longitudinal side facing the first direction and a first plurality of notches formed in the first longitudinal side to provide the elongated member with the relatively low resistance to flexure in the first direction.

### Claim 3 (depends on 2)

The device of claim 2 wherein the elongated member includes a second longitudinal side facing the second direction and a second plurality of notches formed in the second longitudinal side to render the elongated member stable when flexed in the second direction.

### Claim 4 (depends on 1)

The device of claim 1 wherein the elongated member is bent to conform to the shape of the coronary sinus when in a first orientation.

### Claim 5 (depends on 4)

The device of claim 4 wherein the elongated member has a first radius of curvature when in the first orientation, a second radius of curvature when in a second orientation, and wherein the first radius of curvature is less than the second radius of curvature.

### Claim 6

A device that effects the condition of a mitral valve annulus of a heart comprising an elongated member dimensioned to be placed in the coronary sinus of the heart adjacent the mitral valve annulus, the elongated member having a relatively low resistance to flexure in a first direction and a relatively high resistance to flexure in a second direction, wherein the elongated member includes a first longitudinal side facing the first direction and a first plurality of notches formed in the first longitudinal side to provide the elongated member with the relatively low resistance to flexure in the first direction, and wherein the elongated member includes a second longitudinal side facing the second direction and a second plurality of notches formed in the second longitudinal side to render the elongated member stable when flexed in the second direction.

### Claim 7 (depends on 6)

The device of claim 6 wherein the first plurality of notches are larger than the second plurality of notches.

### Claim 8 (depends on 7)

The device of claim 7 wherein the first and second directions lie in the same plane.

### Claim 9 (depends on 6)

The device of claim 6 wherein the first and second longitudinal sides are opposite each other.

### Claim 10 (depends on 9)

The device of claim 9 wherein the first and second directions lie in the same plane.

### Claim 11 (depends on 6)

The device of claim 6 wherein the elongated member is bent to conform to the shape of the coronary sinus when in a first orientation.
