1. A device for treating mitral valve regurgitation, comprising:
- a distal anchor having a collapsed configuration within a delivery device and an expanded configuration with an expanded diameter;
a proximal anchor having a collapsed configuration within the delivery device and an expanded configuration with an expanded diameter; and
a connecting element connecting the distal and proximal anchors,wherein the diameter of the proximal anchor in the expanded configuration is at least about 133% greater than the diameter of the distal anchor in the expanded configuration,wherein each of the distal and proximal anchors are adapted to have the expanded configurations with the expanded diameters external to a patient'"'"'s body.

Abstract
An intravascular support device includes a support or reshaper wire, a proximal anchor and a distal anchor. The support wire engages a vessel wall to change the shape of tissue adjacent the vessel in which the intravascular support is placed. The anchors and support wire are designed such that the vessel in which the support is placed remains open and can be accessed by other devices if necessary. The device provides a minimal metal surface area to blood flowing within the vessel to limit the creation of thrombosis. The anchors can be locked in place to secure the support within the vessel.
