1. A device for modifying the shape of tissue adjacent to a lumen, the device comprising:
- an anchor adapted to securely contact a lumen wall when the device is deployed in a lumen by providing an unequal distribution of anchoring force around a circumferential section of the lumen wall; and
a reshaper extending from the anchor and adapted to contact the lumen wall when the device is deployed in the lumen. wherein the anchor comprises a flexible member extending from the reshaper in a curved path not parallel to the central axis of the lumen, the flexible member being adapted to extend from the axis of the reshaper in at least a first place and a second place the flexible member comprising two arms extending from the first place and two arms extending from the second place, the flexible member being adapted to have the two arms extending from the first place and the two arms extending from the second place meet at a third place.

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.
