Method of anchoring a suture
First Claim

1. A method of repairing soft tissue adjacent a shoulder joint comprising:
- producing a bone tunnel into a bone, the bone tunnel having at least first and second openings at an exterior surface of the bone;
securing a first suture portion and a second suture portion to soft tissue;
positioning the first suture portion so that the first suture portion extends from the soft tissue to the first opening, then through the first opening, and then through the bone tunnel;
positioning the second suture portion so that the second suture portion extends, outside of the bone tunnel, from the soft tissue;
passing the first suture portion through a first transverse anchor passage in an anchor, the anchor comprising a proximal end and a distal end, the first transverse anchor passage extending transversely into the anchor at the distal end and a second transverse anchor passage extending transversely into the anchor at the proximal end;
passing the second suture portion through the second transverse anchor passage in the anchor;
inserting the anchor into the bone tunnel through the second opening; and
advancing a locking member in sliding translation along a path inside the anchor to compress the first and second suture portions between the locking member and the anchor to secure the first and second suture portions relative to the bone tunnel and the anchor, the first and second suture portions being positioned within the bone tunnel when the first and second suture portions are secured with the locking member, such that the first transverse anchor passage through the distal end substantially aligns with the first opening of the bone tunnel when the first suture portion is secured.

Abstract
Suture anchors and associated methods are disclosed having suture locking features able to lock multiple suture ends extending from a body tissue, such as from a bone tunnel, with a single device.

6. A method of repairing soft tissue comprising:
-
forming a bone tunnel in a bone, the bone tunnel having at least first and second spaced apart openings at an exterior surface of the bone; engaging one or more sutures with soft tissue; positioning a first suture portion of the one or more sutures so that the first suture portion extends from the soft tissue to the first opening, then through the first opening, and then through the bone tunnel and out the second opening; positioning a second suture portion of the one or more sutures so that the second suture portion extends, outside of the bone tunnel, from the soft tissue; passing the first suture portion through an anchor, the anchor comprising a proximal end and a distal end, a first transverse anchor passage extending transversely into the anchor nearer the distal end and a second transverse anchor passage extending transversely into the anchor nearer the proximal end, a locking member being translatable along an axis extending between the proximal and distal ends from a first axial position in which the first and second suture portions are able to slide freely within the anchor and a second axial position in which the locking member locks the first and second suture portions relative to the anchor; passing the second suture portion through the anchor; inserting the anchor into the bone tunnel through the second opening; and advancing the locking member in sliding translation along a path inside the anchor to compress the first and second suture portions between the locking member and the anchor to secure the first and second suture portions relative to the bone tunnel and the anchor, the first and second suture portions being positioned within the bone tunnel when the first and second suture portions are secured with the locking member, the securing of the first and second suture portions comprising passing at least the first suture portion through the first transverse anchor passage, passing at least the second suture portion through the second transverse anchor passage, inserting the anchor into the second opening, pulling on at least one of the first and second suture portions so that it moves through the anchor to tension the one or more sutures, and moving the locking member into the second axial position to lock the first and second suture portions relative to the anchor, wherein the locking member deflects the first and second suture portions radially upon moving into the second axial position to trap the first and second suture portions between the locking member and the anchor without further tensioning the first and second suture portions. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15, 16)

17. A method of repairing soft tissue comprising:
-
forming a bone tunnel in a bone, the bone tunnel having at least first and second spaced apart openings at an exterior surface of the bone; engaging a continuous strand of suture with soft tissue; positioning a first suture portion of the continuous strand of suture so that the first suture portion extends from the soft tissue to the first opening, then through the first opening, and then through the bone tunnel; positioning a second suture portion of the continuous strand of suture so that the second suture portion extends, outside of the bone tunnel, from the soft tissue; passing the first suture portion through an anchor; passing the second suture portion through the anchor; inserting the anchor into the bone tunnel through the second opening; after the inserting of the anchor into the bone tunnel, moving a locking member to the anchor; after the inserting of the anchor into the bone tunnel, inserting the locking member into the anchor; and advancing the locking member by sliding the locking member non-rotationally along a longitudinal path inside the anchor to compress the first and second suture portions between the locking member and the anchor to secure the first and second suture portions relative to the bone tunnel and the anchor, the first and second suture portions being positioned within the bone tunnel when the first and second suture portions are secured with the locking member. - View Dependent Claims (18)
