Abstract

An anchor that secures to a connector as part of an anchor assembly is disclosed. The proximal anchor includes a pair of spaced apart prongs which join together at a slot inception. The prongs are shaped and sized of a configuration to define a catch or latching structure. The prongs are configured to capture and deform the suture between the protrusions and prevent the suture from disengaging from the slotted anchor device once engaged.

Claims

1-9. -9. (canceled)

10. An anchor assembly, comprising:

a distal anchor, a connector and a proximal anchor, the proximal anchor comprising;

a back end; and

a pair of spaced prongs extending from the back end, the prongs being joined together at a slot inception, and wherein the prongs are shaped and sized of a configuration to provide deflection of the prongs;

wherein the prongs include inwardly facing structure configured to capture and deform the connector therebetween and a latching structure configured to maintain an engagement with the connector between the prongs;

wherein the latching structure is formed by a pair of crossing prongs.

11. The anchor assembly of claim 10, wherein each prong of the pair of crossing prongs includes a cut-out, the slots arranged to receive a portion of an opposing prong.

12. The anchor assembly of claim 10, wherein a first prong has a first length and the second prong has a second length, the first length being greater than the first length.

16. The anchor assembly of claim 10, further comprising a slot inception, the slot inception is stepped and sized to accept and deform the connector.

17. The anchor assembly of claim 10, the distal anchor comprising a laterally oriented tail.

18. The anchor assembly of claim 17, the distal anchor further comprising a tubular portion which is generally perpendicular to a tail portion.

19. The anchor assembly of claim 18, wherein the tubular portion includes tabs for affixing the distal anchor to the connector.

20. An anchor assembly, comprising:

a distal anchor, a connector and a proximal anchor, the proximal anchor comprising;

a back end; and

a pair of spaced prongs extending from the back end, the prongs being joined together at a slot inception, and wherein the prongs are shaped and sized of a configuration to provide deflection of the prongs;

wherein the prongs include inwardly facing structure configured to capture and deform the connector therebetween and a latching structure configured to maintain an engagement with the connector between the prongs;

wherein the latching structure is defined by a slot formed in a first prong, the slot configured to lockingly receive a second prong.

21. The anchor assembly of claim 20, wherein the proximal anchor is defined by a solid member.

22. The anchor assembly of claim 20, wherein the proximal anchor is defined by a tubular member.

23. The anchor assembly of claim 20, the anchor including a first prong and a second prong, the second prong having a greater length than the first prong.

24. The anchor assembly of claim 20, the proximal anchor further comprising a slot inception, the slot inception is stepped and sized to accept and deform the connector.

25. The anchor assembly of claim 20, distal anchor comprising a laterally oriented tail.

26. The anchor assembly of claim 25, the distal anchor further comprising a tubular portion which is generally perpendicular to a tail portion.

27. The anchor assembly of claim 26, wherein the tubular portion includes tabs for affixing the distal anchor to the connector.
