Abstract

The present disclosure relates to a suture anchor. The suture anchor includes a body having a proximal end and a distal end, the body including threads along at least a partial length of the body and at least one through hole, the threads including a profile such that the threads located near the distal end of the body include a first shape and the threads located near the proximal end of the body include a second shape different from the first shape. Delivery devices and anchor dilators are also disclosed.

Claims

1. (canceled)

2. A delivery device comprising:

a square-shaped end including two prongs extending from the end, the prongs located at opposite corners of the end, wherein the device is cannulated.

3. A delivery device comprising:

an end having a first area and a second area, wherein the first area is of a first shape and the second area is of a second shape different from the first shape, the first shape and the second shape including different diameters, the device being cannulated.

4. A delivery device comprising:

an end having a first area and a second area, wherein the first area is of a first shape and the second area is of a second shape different from the first shape, the first shape and the second shape including different diameters, the device being cannulated, wherein one of the areas includes tangs extending outwardly from the device.

5. An anchor dilator comprising:

a handle;

a shaft coupled to the handle; and

a dilating portion coupled a distal end of the shaft, the dilating portion including a body having threads, the threads including a profile such that the threads located near the distal end of the body include a first shape and the threads located near the proximal end of the body include a second shape different from the first shape.

6. An anchor dilator comprising;

a handle;

a shaft coupled to the handle; and

a dilating portion coupled to a distal end of the shaft, the dilating portion including a body having a threaded first portion and a non-threaded second portion, the threaded first portion including a profile such that threads located near a distal end of the body include a first shape and threads located near a proximal end of the body include a second shape different from the first shape.

7. A method for tissue repair comprising:

inserting an anchor into a prepared bone hole in a bone using an inserter, the anchor having a body including a proximal end, a distal end, and a central axis extending between the proximal and distal ends, the body including threads along at least a partial length of the body and at least one through hole oriented transverse to the central axis of the body, wherein a profile of the threads near the distal end of the body has a first shape and a profile of the threads near the proximal end of the body has a second shape different from the first shape;

rotating the anchor into the bone until the anchor is fully inserted into the bone; and

securing one or more sutures installed in the anchor to a soft tissue.

8. The method of claim 7, wherein rotating the anchor includes cutting a path into the bone with the distal end of the body.

9. The method of claim 7, wherein rotating the anchor includes fixing the anchor into the bone with the proximal end of the body.

10. The method of claim 7, wherein rotating the anchor includes twisting a handle of the inserter.

11. The method of claim 7, further comprising engaging the inserter with a cannulation extending along the central axis, the cannulation intersecting the at least one through hole.

12. The method of claim 11, further comprising engaging a prong of the inserter with a recess defined between the body and a suture bridge of the anchor, wherein the at least one through hole is a single through hole and the suture bridge is formed in the cannulation, the suture bridge extending from the single through hole toward the proximal end of the body.

13. The method of claim 11, wherein the at least one through hole includes a first through hole and a second through hole, the suture anchor further comprising a suture bridge formed in the cannulation, the suture bridge extending between the first through hole and the second through hole, wherein the method further comprises engaging a prong of the inserter with a recess defined around at least a portion of the first through hole.

14. The method of claim 7, further comprising passing the free ends of the one or more sutures through the at least one through hole.

15. The method of claim 7, further comprising:

passing the free ends of the one or more sutures around a suture bridge formed in a cannulation extending along the central axis, the cannulation intersecting the at least one through hole; and

passing the free ends of the one or more sutures through the cannulation.

16. The method of claim 7, further comprising passing the free ends of the one or more sutures through a hollow shaft of the inserter.

17. The method of claim 16, further comprising engaging the hollow shaft of the inserter with a cannulation extending along the central axis, the cannulation intersecting the at least one through hole.
