Abstract

A method of securing a tissue graft within a bone passage includes providing a graft fixation member comprising a closed-loop having a pair of opposing loop sections and capturing a first loop section of the closed-loop within the fixation member. An opposing second loop section of the closed loop is passed through an opening in the tissue graft, and the second loop section of the closed loop is secured to the fixation member.

Claims

1. A method of securing a tissue graft within a bone passage comprising:

providing a graft fixation member comprising a closed-loop having a pair of opposing loop sections;

capturing a first loop section of the closed-loop within the fixation member passing an opposing second loop section of the closed loop through an opening in the tissue graft; and

securing the second loop section of the closed loop to the fixation member.

2. The method of claim 1 further comprising forming the opening in the tissue graft.

3. The method of claim 2 wherein the opening is formed in a bone block of the tissue graft.

4. The method of claim 2 wherein the opening is formed in a tendon of the tissue graft.

5. The method of claim 1 further comprising passing the fixation member through the bone passage.

6. The method of claim 5 wherein passing the fixation member through the bone passage comprises first passing the fixation member through a bone passage in a tibia and then through a bone passage in a femur.

7. The method of claim 5 wherein passing the fixation member through the bone passage comprises first passing the fixation member through a bone passage in a femur and then through a bone passage in a tibia.

8. The method of claim 1 further comprising positioning the fixation member to pass through the bone passage using a suture.

9. The method of claim 1 further comprising positioning the fixation member to pass through the bone passage using closure tape.

10. A method of securing a tissue graft within a bone passage comprising:

providing a graft fixation member comprising a closed loop having a pair of opposing loop sections;

capturing a first loop section of the closed loop within the fixation member;

forming a bight in the closed loop by passing an opposing second loop section of the of the closed loop through an opening in the tissue graft; and

passing the fixation member and the first loop section through the bight in the closed loop to capture the tissue graft.

11. The method of claim 10 further comprising forming the opening in the tissue graft.

12. The method of claim 11 wherein the opening is formed in a bone block of the tissue graft.

13. The method of claim 11 wherein the opening is formed in a tendon of the tissue graft.

14. The method of claim 10 further comprising passing the fixation member through the bone passage.

15. The method of claim 14 wherein passing the fixation member through the bone passage comprises first passing the fixation member through a bone passage in a tibia and then through a bone passage in a femur.

16. The method of claim 14 wherein passing the fixation member through the bone passage comprises first passing the fixation member through a bone passage in a femur and then through a bone passage in a tibia.

17. The method of claim 10 further comprising positioning the fixation member to pass through the bone passage using a suture.

18. The method of claim 10 further comprising positioning the fixation member to pass through the bone passage using closure tape.

19. A method of securing a tissue graft within a bone passage comprising:

providing a first graft fixation member and a second graft fixation member and a closed loop having a pair of opposing loop sections;

capturing a first loop section of the closed loop within the first graft fixation member;

passing an opposing second loop section through an opening in the tissue graft; and

capturing the second loop section of the closed loop of suture within the second graft fixation member.

20. The method of claim 19 further comprising forming the opening in the tissue graft.

21. The method of claim 20 wherein the opening is formed in a bone block of the tissue graft.

22. The method of claim 20 wherein the opening is formed in a tendon of the tissue graft.

23. The method of claim 19 wherein the second loop section is captured within the second fixation member before the second loop section is passed through the opening in the tissue graft.

24. The method of claim 23 wherein passing the second loop section through the opening in the tissue graft comprises passing the second fixation member through the opening.

25. A device for securing a tissue graft within a passage within a bone comprising:

a member comprising an intermediate portion and an end portion;

said end portion comprising a pair of arms extending from the intermediate portion and defining an open channel at said end portion; and

each arm comprising an opening extending from a first side of the arm to a second side of the arm, the opening being sized to accommodate a strand of suture.

26. The device of claim 25 wherein one or more openings pass through the intermediate portion of the member.

27. The device of claim 26 wherein the openings are cylindrical.

28. The device of claim 25 wherein the opening in each arm is cylindrical.

29. The device of claim 25 wherein the openings in each pair of arms occupy different positions on a common axis.

30. The device of claim 29 wherein the axis is transverse to the member.

31. The device of claim 25 wherein the pair of arms define a cylindrical portion of the channel having a diameter equal to the width of the channel.

32. The device of claim 25 wherein each pair of arms define a cylindrical portion of the channel having a diameter greater than the width of the channel.

33. The device of claim 25 wherein the arms are shaped to pass through bone passage.

34. The device of claim 25 wherein the member is sized to pass through a bone passage.

35. The device of claim 25 wherein the member comprises a bio-compatible material.

36. The device of claim 25 wherein the member comprises titanium.

37. The device of claim 25 wherein the member comprises a bio-absorbable material.
