Abstract

An apparatus for tissue repair includes first and second fixation members configured to secure tissue together, a flexible coupling member coupling the first and second fixation members, the flexible coupling member having two terminal ends, one of the two terminal ends terminating adjacent one of the first and second fixation members, the flexible coupling member slidably coupled to at least one of the first and second fixation members such that when the other of the two terminal ends of the flexible coupling member is pulled, a length of the flexible coupling member between the first and second fixation members is shortened, and a closed loop of flexible material, the flexible coupling member being slidably received through the closed loop of flexible material.

Claims

1. An apparatus for tissue repair, comprising:

first and second fixation members configured to secure tissue together;

a flexible coupling member coupling the first and second fixation members, the flexible coupling member including a first closed loop and having two terminal ends, one of the two terminal ends terminating adjacent one of the first and second fixation members, the flexible coupling member slidably coupled to at least one of the first and second fixation members such that when the other of the two terminal ends of the flexible coupling member is pulled, a length of the flexible coupling member between the first and second fixation members is shortened; and

a closed loop of flexible material, the flexible coupling member being slidably received through the closed loop of flexible material.

2. The apparatus of claim 1, wherein the flexible coupling member includes a slip knot.

3. The apparatus of claim 1, wherein the first closed loop is knotless.

4. The apparatus of claim 1, wherein the flexible coupling member comprises a suture.

5. The apparatus of claim 1 being preassembled for use in a surgical procedure.

6. The apparatus of claim 1, wherein the one of the two terminal ends terminating adjacent the one of the first and second fixation members is fixed to the one of the first and second fixation members.

7. The apparatus of claim 1, wherein one of the first and second fixation members defines a cavity that receives at least part of the one of the two terminal ends of the flexible coupling member.

8. The apparatus of claim 1, wherein the flexible coupling member is slidably received through an interior defined by the closed loop of flexible material.

9. An apparatus for tissue repair, comprising:

first and second fixation members configured to secure tissue together;

a flexible coupling member coupling the first and second fixation members, the flexible coupling member including a first closed loop and having two terminal ends, one of the two terminal ends fixed to one of the first and second fixation members, the flexible coupling member slidably coupled to at least one of the first and second fixation members such that when the other of the two terminal ends of the flexible coupling member is pulled, a length of the flexible coupling member between the first and second fixation members is shortened; and

a closed loop of flexible material, the flexible coupling member being slidably received through the closed loop of flexible material.

10. The apparatus of claim 9, wherein the flexible coupling member includes a slip knot.

11. The apparatus of claim 9, wherein the first closed loop is knotless.

12. The apparatus of claim 9, wherein the flexible coupling member comprises a suture.

13. The apparatus of claim 9 being preassembled for use in a surgical procedure.

14. The apparatus of claim 9, wherein the one of the first and second fixation members defines a cavity that receives the one of the two terminal ends of the flexible coupling member.

15. The apparatus of claim 9, wherein the flexible coupling member is slidably received through an interior defined by the closed loop of flexible material.
