Abstract
The present invention relates to a medical device and uses thereof that supports or changes the shape of tissue near a vessel in which the device is placed. The present invention is particularly useful in reducing mitral valve regurgitation by changing the shape of or supporting a mitral valve annulus. The device includes a support structure, a proximal anchor adapted to be positioned in a superior vena cava, and a distal anchor adapted to be positioned in a coronary sinus. The support structure engages a vessel wall to change the shape of tissue adjacent the vessel in which the intravascular support is placed.
