Abstract

A tissue shaping device adapted to be deployed in a vessel to reshape tissue adjacent to the vessel. In some embodiments the device includes first and second anchors and a connector disposed between the first and second anchors, with the connector being integral with at least a portion of the first anchor. The invention is also a method of making a tissue shaping device including the steps of removing material from a blank to form a connector and an integral anchor portion; and attaching a non-integral anchor portion to the integral anchor portion.

Claims

1. A tissue shaping device sized and adapted to be deployed in a human blood vessel to reshape tissue adjacent to the vessel, the device comprising

first and second expandable anchors and a connector disposed between, and integral with, the first and second anchors,

wherein the first anchor comprises a first wire portion secured by a first crimp portion and the second anchor comprises a second wire portion secured by a second crimp portion,

wherein the first and second crimp portions and the connector are formed from a cylinder or flat blank, and wherein a central portion of the blank has been removed to form the connector, and

wherein a distal end of the connector is fixed relative to a proximal end of the first crimp portion, and a proximal end of the connector is fixed relative to a distal end of the second crimp portion.

2. The tissue shaping device of claim 1 wherein the crimp portions and connector are formed from a flat blank and the first and second crimp portions deformed to have a circular cross-section in a plane perpendicular to an axis extending from the first anchor to the second anchor.

3. The tissue shaping device of claim 1 wherein the first crimp portion is adapted to secure of the first wire portion therein.

4. The tissue shaping device of claim 1 wherein the connector has a semicircular cross-section in a plane perpendicular to an axis extending from the first anchor to the second anchor.

5. The tissue shaping device of claim 1 wherein the first crimp portion is adapted to secure of the first wire portion therein and the second crimp portion is adapted to secure of the second wire portion therein.

6. The tissue shaping device of claim 4 wherein the connector has a radius substantially equal to a radius of the first crimp portion.

7. The tissue shaping device of claim 6 wherein the connector has a radius substantially equal to a radius of the second crimp portion.
