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.

Claims

1. A method of modifying target tissue shape comprising:

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;

expanding the distal anchor to anchor the distal anchor in the lumen;

applying a proximally directed force on the distal anchor, wherein applying the proximally directed force on the distal anchor applies a shaping force from the focal deflector against the lumen wall to modify the shape of the target tissue; and

expanding the proximal anchor to anchor the proximal anchor in the lumen,

wherein anchoring the proximal anchor occurs before ceasing the proximally directed force.

2. The method of claim 1 wherein the lumen has a lumen axis, the placing step comprising orienting the focal deflector away from the lumen axis and toward the target tissue.

3. The method of claim 1 wherein the lumen has a lumen axis, the placing step comprising orienting the focal deflector away from the lumen axis and away from the target tissue.

4. A method of modifying target tissue shape comprising:

providing a tissue shaping device comprising proximal and distal anchors, a connector disposed between the proximal and distal anchors, and a focal deflector;

advancing the tissue shaping device to a lumen adjacent the target tissue;

expanding the distal anchor to anchor the distal anchor in the lumen;

applying a proximally directed force on the distal anchor, wherein applying the proximally directed force on the distal anchor applies a shaping force from the focal deflector against the lumen wall to modify the shape of the target tissue; and

expanding the proximal anchor to anchor the proximal anchor,

wherein expanding the proximal anchor occurs while applying the proximally directed force.

5. A method of modifying target tissue shape comprising:

providing a tissue shaping device comprising an expandable distal anchor, an expandable proximal anchor, a connector disposed between the proximal and distal anchors, and a focal deflector;

advancing the tissue shaping device to a lumen adjacent the target tissue;

anchoring the distal anchor in the lumen;

applying a proximally directed force on the distal anchor, wherein applying the proximally directed force on the distal anchor applies a shaping force from the focal deflector against the lumen wall which modifies the shape of the target tissue, and

anchoring the proximal anchor after the shape of the target tissue has been modified.

6. The method of claim 5 wherein anchoring the proximal anchor maintains the modification to the shape of the target tissue caused by the application of the proximally directed force.
