Abstract

An anchor that secures to a connector as part of an anchor assembly is disclosed. The proximal anchor includes deformable structure for engaging a connector.

Claims

1. An anchor assembly for use in treating body tissue, comprising:

a distal anchor;

a connector; and

a proximal anchor, the proximal anchor including a deformable portion and a non-deformable portion spaced longitudinally from the deformable portion, the deformable portion including a space defined by spaced legs with connected terminal ends and sized to receive the connector;

wherein legs are configured to collapse inwardly in part or completely to capture and deform the connector therebetween.

2. The anchor assembly of claim 1, wherein the legs can assume an open position and a closed position.

3. The anchor assembly of claim 1, wherein the anchor further including a slot inception.

4. The anchor assembly of claim 2, wherein the legs include a bend positioned at a mid-section of the legs.

5. The anchor assembly of claim 1, distal anchor comprising a laterally oriented tail.

6. The anchor assembly of claim 5, the distal anchor further comprising a tubular portion which is generally perpendicular to a tail portion.

7. The anchor assembly of claim 6, wherein the tubular portion includes tabs for affixing the distal anchor to the connector.

10. The system of claim 1, distal anchor comprising a laterally oriented tail.

11. The system of claim 5, the distal anchor further comprising a tubular portion which is generally perpendicular to a tail portion.

12. The system of claim 6, wherein the tubular portion includes tabs for affixing the distal anchor to the connector.

8. A system for treating body tissue, comprising:

a distal anchor, a connector, a proximal anchor, the proximal anchor including a deformable portion configured between a first tab and a second tab, the deformable portion including a space sized to receive the connector, wherein the first tab is rotatable with respect to the second tab; and

a delivery apparatus including a rotatable member that receives the first tab and a stabilizing member receiving the second tab, wherein the rotatable member turns the first tab with respect to the second tab to thereby close the deformable portion about the connector.

9. The system of claim 8, wherein the deformable portion is twisted as the rotatable member is rotated.

13. An anchor assembly, comprising:

a distal anchor;

a connector; and

a proximal anchor, the proximal anchor including a deformable portion, the deformable portion being defined by longitudinally collapsible structure, and a non-deformable portion spaced longitudinally from the deformable portion, the deformable portion including a closed space defined by spaced legs sized to receive the connector;

wherein legs are configured to collapse about the non-deformable portion to capture and deform the connector therebetween.

14. The anchor assembly of claim 13, wherein the legs include a bend.

15. The anchor assembly of claim 14, wherein the bend is at a midpoint of the legs.

16. The anchor assembly of claim 14, further comprising a first non-deformable portion and a second non-deformable portion, wherein the deformable portion is configured between the first and second non-deformable portions.

17. The anchor assembly of claim 16, wherein the legs include a bend positioned closer to the first non-deformable portion than the second non-deformable portion.

18. An anchor assembly, comprising:

a distal anchor;

a connector; and

a proximal anchor having a longitudinal dimension, the proximal anchor including a deformable portion, the deformable portion being defined by longitudinally collapsible structure, and a non-deformable portion spaced longitudinally from the deformable portion, the deformable portion including a space defined by spaced legs sized to receive the connector;

wherein legs are configured to bend out of the longitudinal dimension to capture and deform the connector therebetween.

19. The anchor assembly of claim 18, the deformable portion further including a plurality of slots defined by radially spaced longitudinal members.

20. The anchor assembly of claim 19, wherein the radially spaced members project laterally outward when the assembly is deformed longitudinally.

21. An anchoring system for use in treating body tissue, comprising:

a distal anchor;

a connector; and

a proximal anchor, the proximal anchor including a deformable portion and a non-deformable portion spaced longitudinally from the deformable portion, the deformable portion including a space defined by spaced legs with spaced terminal ends and sized to receive the connector;

wherein legs are configured to collapse inwardly so that the legs engage each other to capture and deform the connector therebetween.

22. The anchoring system of claim 21, further comprising a delivery apparatus including a sleeve.

23. The anchoring system of claim 22, wherein a gap between a proximal portion of the legs remains after the sleeve deforms the legs, the gap sized to fix and retain the connector.

24. The anchoring system of claim 23, wherein terminal ends of the legs are deformed to be in contact and parallel.

25. The anchoring system of claim 21, wherein the anchor is defined by a single continuous wall defining a perimeter about a central opening and lateral portions compressible by the sleeve.

26. An anchor assembly for use in treating body tissue, comprising:

a distal anchor;

a connector; and

proximal anchor means for attaching to the connector, the proximal anchor means including a deformable portion and a non-deformable portion spaced longitudinally from the deformable portion, the deformable portion including a closed space defined by spaced legs with connected terminal ends and sized to receive the connector, wherein legs are configured to collapse inwardly to define straightened members to capture and deform the connector therebetween.

27. An anchor assembly, comprising:

a distal anchor;

a connector; and

proximal anchor means for attaching to the connector, the proximal anchor means including a deformable portion, the deformable portion being defined by longitudinally collapsible structure, and a non-deformable portion spaced longitudinally from the deformable portion, the deformable portion including a closed space defined by spaced legs sized to receive the connector, wherein legs are configured to collapse about the non-deformable portion to capture and deform the connector therebetween.

28. An anchor assembly, comprising:

a distal anchor;

a connector; and

proximal anchor means for attaching to the connector and having a longitudinal dimension, the proximal anchor including a deformable portion, the deformable portion being defined by longitudinally collapsible structure, and a non-deformable portion spaced longitudinally from the deformable portion, the deformable portion including a closed space defined by spaced legs sized to receive the connector, wherein legs are configured to bend generally perpendicular to the longitudinal dimension to capture and deform the connector therebetween.

29. An anchoring system for use in treating body tissue, comprising:

a distal anchor;

a connector; and

proximal anchor means for attaching to the connector, the proximal anchor means including a deformable portion and a non-deformable portion spaced longitudinally from the deformable portion, the deformable portion including a closed space defined by spaced legs with spaced terminal ends and sized to receive the connector, wherein legs are configured to collapse inwardly so that the legs engage each other to capture and deform the connector therebetween.
