Abstract
A catheter based system for treating mitral valve regurgitation includes a reshaping device having a body and a plurality of movable anchoring barbs attached to the body of the device. The reshaping device can be made from a biocompatible material having suitable shape memory properties. The devices of the current invention can be self expandable, balloon expandable, or a combination self expandable and balloon expandable. One embodiment of the invention includes a method for attaching a reshaping device to the annulus of a mitral valve, moving the body of the device from a fully expanded configuration to a resting configuration, and thereby reshaping the mitral valve annulus.
