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 near a patient's heart to reshape the patient's heart, the tissue shaping device comprising:
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,
wherein the distal anchor lock comprises a bend in the connector.
2. The device of claim 1 wherein the distal anchor lock further comprises a compliant element adjacent the bend in the connector, the compliant element being adapted to change shape during a distal anchor locking operation.
3. A tissue shaping device adapted to be disposed in a vessel near a patient's heart to reshape the patient's heart, the tissue shaping device comprising:
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,
wherein the connector comprises a first connector, the device further comprising a second connector extending between the proximal and distal anchors.
4. The device of claim 3 wherein the distal anchor lock comprises at least part of the second connector.
5. The device of claim 3 wherein said second connector is adapted to provide fatigue resistance.
6. A tissue shaping device adapted to be disposed in a vessel near a patient's heart to reshape the patient's heart, the tissue shaping device comprising:
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,
wherein the distal anchor comprises a crimp and a wire element extending from the crimp, the wire element having a strain relief portion extending distal of the crimp to form a bend extending substantially below a plane defined by the crimp.
7. The device of claim 6 wherein the distal anchor wire element further comprises a vessel engagement portion extending proximally from the strain relief portion and away from the crimp.
8. The device of claim 7 wherein the distal anchor wire element further comprises a lock portion extending from the vessel engagement portion and forming part of the distal lock.
9. A tissue shaping device adapted to be disposed in a vessel near a patient's heart to reshape the patient's heart, the tissue shaping device comprising:
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,
wherein the proximal anchor comprises a crimp and a wire element extending from the crimp, the wire element having a strain relief portion extending distal of the crimp to form a bend extending substantially below a plane defined by the crimp.
10. The device of claim 9 wherein the proximal anchor wire element further comprises a vessel engagement portion extending proximally from the strain relief portion and away from the crimp.
11. The device of claim 10 wherein the proximal anchor wire element further comprises a lock portion extending from the vessel engagement portion and forming part of the proximal lock.
12. A tissue shaping device adapted to be disposed in a vessel near a patient's heart to reshape the patient's heart, the tissue shaping device comprising:
an expandable proximal anchor, the proximal anchor comprising a crimp and a wire element extending from the crimp, the wire element having a strain relief portion extending distal of the crimp to form a bend extending substantially below a plane defined by the crimp;
an expandable distal anchor, the distal anchor comprising a crimp and a wire element extending from the crimp, the wire element having a strain relief portion extending distal of the crimp to form a bend extending substantially below a plane defined by the crimp; and
a connector extending between the proximal anchor crimp and the distal anchor connector crimp.
13. The device of claim 12 wherein the proximal anchor wire element further comprises a vessel engagement portion extending proximally from the strain relief portion and away from the crimp.
14. The device of claim 12 wherein the distal anchor wire element further comprises a vessel engagement portion extending proximally from the strain relief portion and away from the crimp.
15. The device of claim 12 further comprising a proximal anchor lock adapted to lock the proximal anchor in an expanded configuration.
16. The device of claim 12 further comprising a distal anchor lock adapted to lock the distal anchor in an expanded configuration.
