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.
