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 method of making a tissue shaping device comprising:

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.

2. The method of claim 1 wherein the integral anchor portion comprises a crimp tube and the non-integral portion comprises a flexible wire, the method further comprising disposing a portion of the flexible wire in the crimp tube.

3. The method of claim 1 wherein the blank has a substantially cylindrical cross-section, the removing step comprising removing a portion of the cylinder to leave a connector having a substantially semi-circular cross-section.

4. The method of claim 1 wherein the integral anchor portion is a first integral anchor portion, the removing step further comprising removing material from the blank to form a second integral anchor portion, the connector being disposed between the first integral anchor portion and the second integral anchor portion.

5. The method of claim 4 wherein the first and second anchor portions each comprises a crimp tube and the non-integral anchor portion comprises a flexible wire, the method further comprising disposing a portion of the flexible wire in the first anchor crimp tube.

6. The method of claim 4 wherein the non-integral anchor portion is a first non-integral anchor portion, the method further comprising attaching a second non-integral anchor portion to the second integral anchor portion.

7. The method of claim 6 wherein the first and second integral anchor portions each comprises a crimp tube and the first and second non-integral anchor portions each comprises a flexible wire, the method further comprising disposing a portion of the first anchor flexible wire in the first anchor crimp tube and disposing a portion of the second anchor flexible wire in the second anchor crimp tube.

8. The method of claim 4 wherein the blank has a substantially cylindrical cross-section, the removing step comprising removing a portion of the cylinder to leave a connector having a substantially semi-circular cross-section.
