A device for modifying the shape of a mitral valve annulus. In one
embodiment, the device includes a connector disposed between first and
second anchors, the first and second anchors each adapted to be deployed
in a coronary sinus adjacent the mitral valve annulus to anchor the
device in the coronary sinus; and an actuation element adapted to receive
a proximally or distally directed actuation force from an actuator and to
transmit the actuation force to the first and second anchors
simultaneously. The invention also includes a system for modifying the
shape of a mitral valve annulus, including a percutaneous deployment
apparatus, including an actuator; and a percutaneous mitral valve
annuloplasty device with a connector disposed between first and second
anchors, the first and second anchors each adapted to be deployed in a
coronary sinus adjacent the mitral valve annulus to anchor the device in
the coronary sinus; and an actuation element adapted to receive a
distally proximally directed actuation force from the actuator and to
transmit the actuation force to the first and second anchors
simultaneously. The invention also includes a method of using such
devices and systems.
