Device and Method for Modifying the Shape of a Body Organ

Abstract

A tissue shaping device adapted to be deployed in a lumen to modify the shape of target tissue adjacent to the lumen. In one embodiment the device includes first and second anchors; a connector disposed between the first and second anchors; and a focal deflector disposed between the first and second anchors and may be adapted to extend away from the lumen axis and toward the target tissue and/or away from the lumen axis and away from the target tissue when the device is deployed in the lumen. The invention is also a method of modifying target tissue shape. The method includes the steps of providing a tissue shaping device comprising proximal and distal anchors, a connector disposed between the proximal and distal anchors, and a focal deflector; placing the tissue shaping device in a lumen adjacent the target tissue; applying a shaping force from the focal deflector against a lumen wall to modify the shape of the target tissue; and expanding the proximal and distal anchors to anchor the device in the lumen.

         2 . The device of  claim 1  wherein the lumen has a lumen axis, the focal deflector being adapted to extend away from the lumen axis and toward the target tissue when the device is deployed in the lumen. 
     
     
         3 . The device of  claim 1  wherein the lumen has a lumen axis, the focal deflector being adapted to extend away from the lumen axis and away from the target tissue when the device is deployed in the lumen. 
     
     
         4 . The device of  claim 1  wherein the focal deflector comprises an expandable portion. 
     
     
         5 . The device of  claim 4  wherein the expandable portion is adapted to be self-expanding. 
     
     
         6 . The device of  claim 4  wherein the expandable portion is adapted to be expanded by an actuation force. 
     
     
         7 . The device of  claim 4  further comprising a lock locking the focal deflector in an expanded configuration. 
     
     
         8 . The device of  claim 1  further comprising an attachment element attaching the focal deflector to the connector. 
     
     
         9 . The device of  claim 1  wherein the focal deflector is integral with the connector. 
     
     
         10 . The device of  claim 9  wherein the focal deflector comprises a bend in the connector. 
     
     
         11 . The device of  claim 10  wherein the lumen has a lumen axis, the focal deflector being adapted to extend away from the lumen axis and toward the target tissue when the device is deployed in the lumen. 
     
     
         12 . The device of  claim 9  wherein the connector has a linear shape, the focal deflector comprising a local change to the linear shape. 
     
     
         13 . The device of  claim 12  wherein the connector linear shape is a curved line, the focal deflector comprising a portion of increased curve of the curved line. 
     
     
         14 . The device of  claim 9  wherein the focal deflector comprises a flattened portion of the connector. 
     
     
         15 . The device of  claim 1  wherein the focal deflector comprises an expandable anchor. 
     
     
         16 . The device of  claim 15  wherein the lumen has a lumen axis, the focal deflector further comprising a portion integral with the connector and adapted to extend away from the lumen axis and toward the target tissue when the device is deployed in the lumen. 
     
     
         17 . A tissue shaping device adapted to be deployed in a lumen to modify the shape of target tissue adjacent to the lumen, the device comprising:
 an expandable anchor;   a focal deflector;   a connector disposed between the anchor and the focal deflector; and   a tail extending from the focal deflector away from the anchor.   
     
     
         18 . The tissue shaping device of  claim 17  wherein the focal deflector comprises an expandable portion. 
     
     
         19 . The device of  claim 17  wherein the lumen has a lumen axis, the focal deflector being adapted to extend away from the lumen axis and away from the target tissue when the device is deployed in the lumen.
