Anchor and pull mitral valve device and method

Abstract

A device, system, and method effects mitral valve annulus geometry of a heart. The device includes a first anchor configured to be positioned within and fixed to the coronary sinus of the heart adjacent the mitral valve annulus within the heart. A cable is fixed to the first anchor and extends proximately therefrom and slidingly through a second anchor which is positioned and fixed in the heart proximal to the first anchor. A lock locks the cable to the second anchor when tension is applied to the cable for effecting the mitral valve annulus geometry.
