Abstract

A coiled anchor that secures to a connector as part of an anchor assembly is disclosed. The coiled anchor includes windings which capture and deform the connector between the windings and prevent the connector from disengaging from the coiled anchor once engaged.

Claims

1. A system for delivering an anchor assembly for applying retractive pressure to tissue, comprising:

a distal anchor, wherein the distal anchor includes a head portion that is connected to a generally perpendicularly oriented tail portion via a connecting mid-section portion;

a suture, wherein the suture is attachable and tensioned to the distal anchor; and

a coiled proximal anchor for securing the suture as part of a proximal end of the anchor assembly, the coiled proximal anchor including a body, a portion of which includes coils with varying pitch, and a plug sized to be received within an internal bore of the body.

2. The system of claim 1, wherein the varying pitch extends from a first end of the body to a midsection of the body.

3. The system of claim 1, wherein the varying pitch extends a full length of the body.

4. The system of claim 1, further comprising a delivery apparatus, the delivery apparatus including a slot for registering the coiled proximal anchor.

5. The system of claim 4, the delivery apparatus including means for rotating the coiled proximal anchor onto the suture.

6. The system of claim 1, wherein the body includes coils spaced to grasp and bite into the suture.

7. The system of claim 6, wherein the coils are formed from a flat wire having edges that bite into the suture.

8. The system of claim 1, wherein the proximal anchor is formed from a bifilar winding of two wires.

9. The system of claim 8, wherein the varying pitch is created by the bifilar winding.

10. The system of claim 1, the proximal anchor further comprising a tubular portion connected to a coil portion.

11. The system of claim 10, wherein the coil portion is intended to assume both longitudinally extended and contracted configurations.

12. The system of claim 11, wherein the coiled portion grasps the suture when in the contracted configuration.

13. The system of claim 1, wherein the delivery apparatus includes means for translating the plug within the internal bore.

14. The system of claim 1, the plug further comprising a slot for receiving and engaging the suture.

15. The system of claim 1, wherein the distal anchor includes a distal coil portion connected to the tail portion.

16. A system for delivering an anchor assembly for applying retractive pressure to tissue, comprising:

a distal anchor, wherein the distal anchor includes a head portion that is connected to a generally perpendicularly oriented tail portion via a connecting mid-section portion;

a suture, wherein the suture is attachable and tensioned to the distal anchor; and

a coiled proximal anchor for securing the suture as part of a proximal end of the anchor assembly, the coiled proximal anchor including a body, a portion of which includes coils with varying pitch, and the proximal anchor further comprising an H-shaped substructure configured to receive the body of the coiled proximal anchor.

17. The system of claim 16, wherein the varying pitch extends from a first end of the body to a midsection of the body.

18. The system of claim 16, wherein the varying pitch extends a full length of the body.

19. The system of claim 16, further comprising a delivery apparatus, the delivery apparatus including a slot for registering the coiled proximal anchor.

20. The system of claim 19, the delivery apparatus including means for rotating the coiled proximal anchor onto the suture.

21. The system of claim 16, wherein the body includes coils spaced to grasp and bite into the suture.

22. The system of claim 21, wherein the coils are formed from a flat wire having edges that bite into the suture.

23. The system of claim 16, wherein the coiled proximal anchor is formed from a bifilar winding of two wires.

24. The system of claim 23, wherein the varying pitch is created by the bifilar winding.

25. The system of claim 16, the coiled proximal anchor further comprising a tubular portion connected to a coil portion.

26. The system of claim 25, wherein the coil portion is intended to assume both longitudinally extended and contracted configurations.

27. The system of claim 26, wherein the coiled portion grasps the suture when in the contracted configuration.

28. The system of claim 16, wherein the H-shaped substructure includes a first arm sized to receive a first coil and a second arm sized to receive a second coil.

29. The system of claim 16, wherein the distal anchor includes a distal coil portion connected to the tail portion.
