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. 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 the connector therebetween and a latching structure configured to maintain an engagement with the connector between the prongs;

wherein the proximal anchor includes a body and an extension configured to be folded laterally across the body.

2. The anchor assembly of claim 1, wherein a terminal end of the extension includes structure for lockingly engaging with the body.

3. The anchor assembly of claim 1, wherein the proximal anchor is defined by a solid member.

4. The anchor assembly of claim 1, wherein the proximal anchor is defined by a tubular member.

5. The anchor assembly of claim 1, the pair of spaced prongs including a first prong and a second prong, the second prong having a greater length than the first prong.

6. The anchor assembly of claim 1, wherein the slot inception is stepped and sized to accept and deform the connector.

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

8. The anchor assembly of claim 7, the distal anchor further comprising a tubular portion which is generally perpendicular to a portion of the tail portion.

9. The anchor assembly of claim 8, wherein the tubular portion includes tabs for affixing the distal anchor to the connector.
