Abstract
Abstract A device effects the mitral valve annulus geometry of a heart. The device includes a first anchor configured to be positioned within and anchored to the coronary sinus of the heart adjacent the mitral valve annulus within the heart and a second anchor configured to be positioned within the coronary sinus of the heart proximal to the first anchor and adjacent the mitral valve annulus within the heart. The second anchor, when deployed, anchors against distal movement and is moveable in a proximal direction. The device further includes a connecting member having a fixed length permanently attached to the first and second anchors. As a result, when the first and second anchors are within the coronary sinus with the first anchor anchored in the coronary sinus, the second anchor may be displaced proximally to effect the geometry of the mitral valve annulus and released to maintain the effect on the mitral valve geometry.
