Tissue shaping device
View Patent ↗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.
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;
an expandable second anchor having an expanded 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 element including a strain relief portion in which the wire elements extends axially, and below an axis of the connector.
2. The tissue shaping device of claim 1 wherein the strain relief portion, after extending radially away from the axis of the connector, extends back radially towards the axis of the connector.
3. The tissue shaping device of claim 1 , further comprising a first lock to lock the first anchor in the expanded configuration.
4. The tissue shaping device of claim 3 , further comprising a second lock to lock the second anchor in the expanded configuration.
5. The tissue shaping device of claim 1 , wherein the first and second anchors each comprise a wire element including a strain relief portion in which the wire elements extends axially, and radially away from an axis of the connector.
6. The tissue shaping device of claim 1 , wherein the strain relief portion is disposed at a distal end of the anchor.
7. The tissue shaping device of claim 1 , wherein the strain relief portion comprises a bend in the wire element.
