Abstract

In one embodiment, the present invention relates to a tissue shaping device adapted to be disposed in a vessel near a patient'"'"'s heart to reshape the patient'"'"'s heart. Such tissue shaping device can include an expandable proximal anchor; a proximal anchor lock adapted to lock the proximal anchor in an expanded configuration; an expandable distal anchor; a distal anchor lock adapted to lock the distal anchor in an expanded configuration; and a connector disposed between the proximal anchor and the distal anchor, the connector having a substantially non-circular cross-section.

Claims

1. A tissue shaping device for reshaping a patient'"'"'s heart tissue, comprising:

a distal anchor adapted to be anchored within a heart, a proximal anchor adapted to be anchored within the heart, a first connector extending between the distal and proximal anchors, and a second connector extending between the distal and proximal anchors wherein the first connector has a substantially rectangular cross section.

3. The device of claim 1 wherein the second connector has a substantially circular cross section.

4. The device of claim 3 wherein the second connector is a wire connector.

5. The device of claim 1 wherein the first and second connectors each have a fixed length between the distal and proximal anchors.

6. The device of claim 1 wherein the device comprises a lock to lock the distal anchor in an expanded and locked configuration, and wherein the first connector comprises a first lock element that interacts with a portion of the anchor to lock the distal anchor in the expanded and locked configuration.

7. The device of claim 6 wherein the first lock element comprises a bend in the first connector.

8. The device of claim 6 wherein the second connector comprises a second lock element which interacts with the portion of the anchor to lock the distal anchor in the expanded and locked configuration.

9. The device of claim 8 wherein the second lock element comprises a bend in the second connector.

10. The device of claim 1 wherein the distal anchor and the proximal anchor are expandable.

2. A tissue shaping device for reshaping a patient'"'"'s heart tissue, comprising:

a distal anchor adapted to be anchored within a heart, a proximal anchor adapted to be anchored within the heart, a first connector extending between the distal and proximal anchors, and a second connector extending between the distal and proximal anchors wherein the first connector has a substantially flat shape.

11. A tissue shaping device for reshaping a patient'"'"'s heart tissue, comprising:

a distal anchor adapted to be anchored within a heart, a proximal anchor adapted to be anchored within the heart, a first connector extending between the distal and proximal anchors, and a second connector extending between the distal and proximal anchors, wherein one of the first and second connectors has a non-circular cross-section.

12. The tissue shaping device of claim 11 wherein both of the connectors extend from the distal anchor to the proximal anchor.

13. The tissue shaping device of claim 11 wherein the first connector has a substantially rectangular cross section.

14. The tissue shaping device of claim 13 wherein the second connector has a substantially circular cross section.

15. The tissue shaping device of claim 11 wherein the first connector has a substantially flat shape and the second connector is a wire connector.
