Devices, systems, and methods for attaching soft tissue to bone tissue
A suture anchoring device for fixing a soft tissue to a bone tissue is disclosed that enables the exchange of sutures between anchors after implantation. The suture anchoring device may include a body that is inserted into the bone tissue, a suture exchange fitting situation within a passage formed within the body, and one or more pre-loaded sutures looped through the suture exchange fitting and projecting proximally from a proximal opening formed in the body. Surgical kits and surgical methods for performing various repair procedures using one or more suture anchoring device are also disclosed.
1. A method of securing soft tissue to bone, the method comprising:
inserting a first suture anchor into bone at a first location, the first suture anchor comprising:
a proximal anchor body comprising a first inner lumen having a first proximal opening, a distal opening, and external threads,
a distal anchor tip comprising a distal exterior portion, a rigid proximal shaft, and a first eyelet, wherein the rigid proximal shaft and the first eyelet is configured to be received through the distal opening of the proximal anchor body to form a first internal eyelet positioned within the first inner lumen,
a first elongated loading member threaded through the first eyelet, wherein the first elongated loading member comprises a first aperture, and
a first suture extending from the first suture anchor;
inserting a second suture anchor into bone at a second location, the second suture anchor comprising:
a second proximal anchor body comprising a second inner lumen having a second proximal opening, a second distal opening, and external threads,
a distal anchor tip comprising a second distal exterior portion, a second rigid proximal shaft, and a second eyelet, wherein the second rigid proximal shaft and the second eyelet is configured to be received through the second distal opening of the second proximal anchor body to form a second internal eyelet positioned within the second inner lumen,
a second elongated loading member threaded through the second eyelet, wherein the second elongated loading member comprises a second aperture, and
a second suture extending from the second suture anchor;
passing the second suture through the first aperture of the first elongated loading member;
pulling on one end of the first elongated loading member to pull the second suture through the first eyelet; and
pulling on the second suture to tension the second suture over the soft tissue such that second suture extends from within the second inner lumen, through the second proximal opening, over the soft tissue, through the first proximal opening, and into the first inner lumen.
2. The method of claim 1 , comprising forming first and second bore holes in the bone and wherein inserting the first suture anchor comprises inserting the first suture anchor into the first bore hole and inserting the second suture anchor comprises inserting the second suture anchor into the second bore hole.
3. The method of claim 1 , wherein the first internal eyelet is formed by transverse bar within the first inner lumen.
4. The method of claim 3 , wherein the first suture anchor comprises side apertures adjacent to the transverse bar.
5. The method of claim 1 , wherein the first aperture comprises a loop in the first elongated loading member.
6. The method of claim 5 , wherein the first elongated loading member comprises a suture.
7. The method of claim 1 , wherein the second suture is passed over the soft tissue prior to passing the second suture through the first aperture.
8. The method of claim 1 , comprising removing the first elongated loading member after pulling the second suture through the first eyelet.
9. The method of claim 1 , wherein the second suture is secured by knotless fixation.
10. The method of claim 1 , comprising, after pulling on the second suture, passing the second suture to a third anchor and securing the second suture to the third anchor, wherein the third anchor is a knotless anchor.
11. The method of claim 10 , wherein the first and second anchors are positioned beneath the soft tissue and the third anchor is positioned beyond an edge of the soft tissue.
12. The method of claim 1 , wherein a lateral-medial bridge suture pattern is formed.
13. The method of claim 1 , wherein a medial bridge suture pattern is formed.
14. The method of claim 1 , wherein a two-anchor parallel horizontal repair is completed.
15. The method of claim 1 , comprising forming a repair comprising two sutures extending between the first and second anchors.
16. The method of claim 1 , comprising:
passing the first suture through the second aperture on the second elongated loading member; and
pulling on one end of the second elongated loading member to pull the first suture through the second eyelet.
17. The method of claim 16 , comprising pulling on the first suture to tension the first suture over the soft tissue such that first suture extends from within the first inner lumen, through the first proximal opening, over the soft tissue, through the second proximal opening, and into the second inner lumen.
