Abstract

A bone anchor configured for use in anchoring an implanting portion to an anchor point. A bone anchor can be of particular use in anchoring soft tissue to a bone. A bone anchor can have a wire loop and a suture. The wire loop of the bone anchor can be configured to capture a suture and to pull a portion of the suture through a hole in the anchor body aiding in anchoring an item, such as tissue to a bone. Methods of using the bone anchor with a suture and a wire loop to attach an item are disclosed

First claim

1 . A method of securing soft tissue to a bone anchor comprising:
inserting the bone anchor into a patient through a first arthroscopic port, wherein the bone anchor comprises:
an expandable anchor body;
an expander comprising:
at least one expansion portion; and
a first opening and a second opening in a distal end of the expander;
wherein the expander is displaceable between a first position relative to the anchor body and a second position relative to the anchor body, wherein the expansion portion is configured to expand the anchor body when the expander is in the second position; and a retractable suture grabber extending through the first opening and a non-looped suture separately extending through the second opening;

pulling the suture grabber out of the patient through a second arthroscopic port; passing a suture around soft tissue; pulling at least a first limb of the suture out of the patient through the second arthroscopic port; engaging the suture with the suture grabber; and retracting the suture grabber through the first opening in the distal end of the expander, thereby pulling the first limb of the suture through the first opening.

2 . The method of claim 1 , wherein the suture grabber comprises a wire loop and engaging the suture with the suture grabber comprises passing the suture through the wire loop.

3 . The method of claim 1 , wherein a second limb of the suture extends through the first opening in the distal end of the expander prior to insertion of the bone anchor.

4 . The method of claim 1 , wherein a second limb of the suture extends through a second opening the distal end of the expander prior to insertion of the bone anchor.

5 . The method of claim 1 , further comprising inserting the first limb of the suture through the second arthroscopic port prior to passing it around the soft tissue.

6 . The method of claim 1 , wherein both the first limb and a second limb of the suture is engaged with the suture grabber and both the first and second limbs are pulled through the first opening when the suture grabber is retracted.

7 . The method of claim 15 , further comprising making a hole in bone.

8 . The method of claim 7 , wherein the hole is made with a drill.

9 . The method of claim 7 , further comprising clearing the bone of any soft tissue in the region of the hole.

10 . The method of claim 2 , further comprising inserting the anchor into the bone after retracting the suture grabber.
