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.

DETAILED DESCRIPTION The present invention provides a device for effecting 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 fixed to the first anchor and extending proximally from the first anchor within the heart, a second anchor configured to be positioned in and fixed in the heart proximal to the first anchor and arranged to slidingly receive the cable, and a lock that locks the cable on the second anchor.
As a result, when the first and second anchors are fixed within the heart, the cable is drawn proximally, and the cable is locked on the second anchor, the geometry of the mitral valve is effected.
The second anchor may be configured to be positioned and fixed in the coronary sinus.
Alternatively, the second anchor may be configured to be positioned and fixed in the right atrium.
The first anchor may be self-expanding to fix the first anchor in the coronary sinus.
Similarly, the second anchor may be self-expanding to fix the second anchor in the heart.
The second anchor may include the lock.
The lock may include a ratchet.
Further, the cable may include a coupling configured for releasable connection to a cable tension assembly.
The present invention further provides a device for effecting mitral valve annulus geometry in a heart including first anchor means for anchoring within the coronary sinus of the heart adjacent to the mitral valve annulus and second anchor means for anchoring within the heart proximal to the first anchor means.
The device further includes cable means fixed to the first anchor means and extending proximally from the first anchor means, the cable means being slidably received by the second anchor means for spanning between the first and second anchor means, and lock means for locking the second anchor means to the cable means.
The present invention still further provides a method of effecting mitral valve annulus geometry in a heart
