Abstract

Suture passer devices, including suture passers configured with an axially slideable jaw that includes a tissue-penetrating distal end region. Also described are suture passers including jaws housing tissue penetrating needles to pass suture that are substantially thin. Methods of using such devices to pass a suture through tissue are provided.

Claims

1. A suture passer device for passing a suture, the device comprising:

an elongate body extending distally and proximally along a long axis;

a first jaw extending from a distal end region of the elongate body wherein the first jaw is bent or bendable at an angle relative to the long axis;

a second jaw having a sharp, tissue penetrating distal tip, wherein the second jaw is configured to slide axially along the long axis distally and proximally relative to the elongate body, further wherein the first jaw and the second jaw form a distal-facing opening when the second jaw is extended distally and wherein the second jaw is retractable proximally so that it does not form the distal-facing opening with the first jaw; and

a tissue penetrator configured to extend across the distal-facing opening between the first jaw and the second jaw to pass a suture there between.

2. The device of claim 1, wherein the tissue penetrating distal tip of the second jaw comprises a sharp distal tip.

3. The device of claim 1, wherein the tissue penetrating distal tip of the second jaw comprises a sharp point at the distal tip.

4. The device of claim 1, wherein the first jaw comprises an atraumatic distal tip region.

5. The device of claim 1, wherein the first jaw is hinged to the distal end region of the elongate body.

6. The device of claim 1, wherein the first jaw is bent at a predetermined angle relative to the long axis of the elongate body.

7. The device of claim 1, wherein a second jaw is configured to retract into the elongate body.

8. The device of claim 1, further comprising a handle at a proximal end region of the elongate body.

9. The device of claim 1, wherein the tissue penetrator comprises a strip of shape-memory material.

10. The device of claim 1, wherein the tissue penetrator comprise a suture holding region.

11. The device of claim 1, wherein the tissue penetrator is housed in the second jaw and configured to extend from an opening on the side of the second jaw.

12. The device of claim 1, wherein the first jaw comprises a suture retainer configured to receive and hold a suture from the tissue penetrator.

13. A method of suturing tissue using a suture passer having an elongate body, a first jaw bent or bendable relative to the elongate body, and a sharp, tissue penetrating axially slideable second jaw, the method comprising:

positioning the first jaw of the suture passer adjacent a tissue with the second jaw retracted proximally relative to the elongate body;

axially sliding the second jaw distally to penetrate the tissue by extending the second jaw distally by relative to the elongate body;

extending a tissue penetrator through the tissue between the first and second jaws to pass a suture between the first and second jaws;

retracting the tissue penetrator from between the first and second jaws; and

sliding the second jaw proximally out of the tissue while leaving the suture in the tissue.

14. The method of claim 13, wherein positioning the first jaw comprises bending the first jaw relative to a long axis of the elongate body.

15. The method of claim 13, wherein positioning the first jaw comprises positioning the first jaw of the suture passer with a sharp tissue penetrating distal tip of the second jaw retracted into the elongate body.

16. The method of claim 13, wherein axially sliding the second jaw comprises extending a sharp, tissue penetrating distal tip region of the second jaw into the tissue.

17. The method of claim 13, wherein extending the tissue penetrator through the tissue comprises extending a tissue penetrator from a side of the second jaw to a side of the first jaw.

18. The method of claim 13, wherein extending the tissue penetrator comprises extending the tissue penetrator in a curve between the first and second jaws.

19. The method of claim 13, wherein extending the tissue penetrator comprises pushing a suture between the first and second jaws.

20. The method of claim 13, further comprising retaining the suture in the first jaw.

21. The method of claim 13, wherein retracting the tissue penetrator comprises retracting the tissue penetrator into the second jaw.

22. The method of claim 13, wherein the first jaw is positioned arthroscopically.
