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 adapted to be disposed in a vessel and reshape a patient'"'"'s heart, comprising:

an expandable first anchor having an expanded configuration and a collapsed configuration;

an expandable second anchor having an expanded configuration and a collapsed configuration; and

a connector disposed between the first anchor and the second anchor,

wherein at least one of the first and second anchors comprises a wire that has a collapsed position when the respective anchor is in the collapsed configuration and an expanded position when the respective anchor is in the expanded configuration,

wherein the wire comprises a strain relief portion disposed at a distal end of the anchor, the strain relief portion comprising a bend about which the wire deforms when the respective anchor deforms from the expanded configuration to the collapsed configuration, wherein in the strain relief portion the wire extends below an axis of the connector.

2. The tissue shaping device of claim 1, wherein the wire, after extending below the axis of the connector, extends back towards the axis of the connector.

3. The tissue shaping device of claim 2, wherein after extending back towards the axis of the connector, the wire extends above the axis of the connector.

4. The tissue shaping device of claim 1, further comprising a first lock to lock the first anchor in the expanded configuration.

5. The tissue shaping device of claim 1, further comprising a second lock to lock the second anchor in the expanded configuration.

6. The tissue shaping device of claim 1, wherein the first and second anchors each comprise a wire that has a collapsed position when the respective anchor is in the collapsed configuration and an expanded position when the respective anchor is in the expanded configuration, wherein each of the wires comprise a strain relief portion disposed at a distal end of the anchor, the strain relief portion comprising a bend about which the wire deforms when the respective anchor deforms from the expanded configuration to the collapsed configuration, wherein in the strain relief portions the wires extend below an axis of the connector.

7. The tissue shaping device of claim 1, wherein the strain relief portion comprises a bend in the wire.
