Abstract

Methods of repairing knee meniscus tears are described which use suture passer devices and suture shuttles. These methods may be used with continuous suture passing, so that the suture passer device may remain on or in the tissue while passing a suture shuttle, and therefore a suture, back and forth from one side of the tissue to the other. These methods may be used minimally invasively for repairing meniscus tissue while avoiding further damage to the meniscus.

Claims

1. A method of repairing or reconstructing a tissue with a suture passer, wherein the suture passer has an elongate body with a proximal to distal long axis, a distal first arm and a distal second arm, wherein the first arm is configured to slide in the long axis to form a distal-facing opening with the second arm, the method comprising:

positioning the second arm of the suture passer on one side of the tissue;

sliding the first arm of the suture passer distally in the long axis so that the tissue is positioned within the distal-facing opening formed between the first and second arms; and

passing a suture through the tissue between the first arm and the second arm by extending a tissue penetrator through the tissue between the first arm and the second arm and retracting the tissue penetrator back through the tissue.

2. The method of claim 1, wherein positioning the second arm comprises positioning a bent distal region of the second arm on one side of the tissue.

3. The method of claim 1, wherein positioning the second arm comprises positioning the second arm relative to the tissue while the first arm is retracted proximally so that it does not form a distal opening with the second arm.

4. The method of claim 1, wherein sliding the first arm comprises extending the first arm from within a proximal region of the elongate body.

5. The method of claim 1, wherein sliding the first arm comprises forming a distal-facing opening between the first arm and a bent distal region of the second arm.

6. The method of claim 1, wherein extending the tissue penetrator comprises extending the tissue penetrator from the first arm and through the tissue to the second arm.

7. The method of claim 6, wherein extending the tissue penetrator comprises pushing a suture coupled with the tissue penetrator from the first arm through the tissue to the second arm using the tissue penetrator.

8. The method of claim 1, wherein retracting the tissue penetrator comprises pulling a suture coupled with the tissue penetrator from the second arm through the tissue to the first arm.

9. The method of claim 1, further comprising repositioning the suture passer relative to the tissue and extending and retracting the tissue penetrator to pass a second length of suture through the tissue.

10. The method of claim 1, wherein the tissue comprises meniscus tissue.

11. A method of repairing or reconstructing a meniscus of a knee with a suture passer, wherein the suture passer has an elongate body with a proximal to distal long axis, a first arm and a second arm, and wherein the first arm is configured to slide in the long axis to form a distal-facing opening with the second arm, the method comprising:

positioning the second arm of the suture passer on one side of the meniscus;

sliding the first arm of the suture passer distally in the long axis to form the distal-facing opening between the first and second arms wherein the meniscus is within the distal-facing opening; and

passing a suture through the meniscus by extending a tissue penetrator across the distal-facing opening between the first and second arms, and retracting the tissue penetrator back through the meniscus.

12. The method of claim 11, wherein positioning the second arm comprises positioning a bent distal region of the second arm on one side of the meniscus, further wherein the bent distal is bent relative to the elongate body.

13. The method of claim 11, wherein positioning the second arm comprises positioning a bent distal region of the second arm on the superior side of the meniscus.

14. The method of claim 11, wherein sliding the first arm comprises axially moving the first arm of the suture passer in the long axis relative to the second arm of the suture passer.

15. The method of claim 11, wherein sliding the first arm comprises extending the first arm adjacent to the inferior side of the meniscus.

16. The method of claim 11, wherein passing the suture comprises extending the tissue penetrator from the first arm and through the meniscus to the second arm.

17. The method of claim 11, wherein passing the suture comprises extending the tissue penetrator from the first arm and through the meniscus to the second arm and pushing a suture from the first arm through the meniscus to the second arm using the tissue penetrator.

18. The method of claim 11, wherein retracting the tissue penetrator comprises retracting the tissue penetrator back from the second arm and pulling a suture from the second arm through the meniscus and to the first arm using the tissue penetrator.

19. The method of claim 11, further comprising repositioning the suture passer relative to the meniscus and extending and retracting the tissue penetrator to pass a second length of suture through the meniscus.

20. A method of repairing or reconstructing a tissue with a suture passer, wherein the suture passer has an elongate body with a proximal to distal long axis, a distal first arm and a distal second arm, wherein the first arm is configured to slide in the long axis to form a distal-facing opening with the second arm, the method comprising:

positioning a bent distal region of the second arm of the suture passer on one side of the tissue;

sliding the first arm distally in the long axis to form the distal-facing opening, so that the tissue is positioned within the distal-facing opening between the first and second arms; and

passing a suture through the tissue between the first arm and the second arm by extending a tissue penetrator through the tissue between the first arm and the second arm, and retracting the tissue penetrator back through the tissue.

21. The method of claim 20, wherein the tissue comprises meniscus tissue.

22. A method of repairing or reconstructing a meniscus of a knee with a suture passer, wherein the suture passer has an elongate body with a proximal to distal long axis, a slideable distal first arm and distal second arm having a distal region configured to form a bend relative to the elongate body, further wherein the first arm is configured to slide in the long axis to form a distal-facing opening with the second arm, the method comprising:

positioning the bent region of the second arm on the superior side of the meniscus;

sliding the first arm distally in the long axis and under the inferior side of the meniscus so that the meniscus is within the distal-facing opening formed between the first and second arms;

passing a suture through the tissue between the first and second arms by extending a tissue penetrator from the first arm and through the meniscus to the second arm, and retracting the tissue penetrator back through the meniscus from the second arm to the first arm.

23. The method of claim 22, wherein extending the tissue penetrator from the first arm and through the meniscus to the second arm comprises pushing a suture from the first arm through the meniscus to the second arm using the tissue penetrator.

24. The method of claim 22, wherein retracting the tissue penetrator back from the second arm comprises pulling a suture from the second arm through the meniscus and to the first arm using the tissue penetrator.
