Abstract

A method for coupling tissue includes aligning a guide tool on an outer surface of a first tissue; forming a bore in the first tissue aligned with the guide tool; deploying a non-slip suture construct through the guide tool and into the bore; adjusting a saddle along a flexible member to a position adjacent to a soft anchor, wherein the saddle prevents the flexible member from slideably moving relative to the soft anchor; and threading the flexible member through a second tissue to secure the second tissue to the first tissue.

Claims

1. A method for coupling tissue, comprising:

aligning a guide tool on an outer surface of a first tissue;

forming a bore in the first tissue aligned with the guide tool;

deploying a non-slip suture construct through the guide tool and into the bore, the nonslip suture construct including a flexible member and a soft anchor, the flexible member comprising a first portion and a second portion, the first portion being threaded through the second portion to form a saddle, wherein said deploying includes positioning the soft anchor in the bore with the saddle spaced a distance from the soft anchor along the flexible member;

adjusting the saddle along the flexible member after said positioning so as to move the saddle toward the soft anchor along the flexible member and into abutment with the soft anchor in the bore, wherein the saddle resists the flexible member from slideably moving relative to the soft anchor; and

threading the flexible member through a second tissue to secure the second tissue to the first tissue.

2. The method of claim 1 further comprising fixing a secondary anchor to the first tissue.

3. The method of claim 2 further comprising fixing an end of the flexible member to the secondary anchor to secure the second tissue to the first tissue.

4. The method of claim 3 further comprising creating a web of flexible members to secure the second tissue to the first tissue by implanting a plurality of non-slip suture constructs and secondary anchors.

5. The method of claim 1 wherein the first tissue is a humerus and the second tissue is a rotator cuff.

6. The method of claim 1, wherein said adjusting moves the saddle into the bore from a location outside the bore.

7. The method of claim 1, wherein the saddle compresses the soft anchor within the bore, deforming the soft anchor.

8. A method for coupling tissue, comprising:

forming a bore in a bone;

deploying a soft anchor of a suture construct into the bore, wherein the suture construct includes a flexible member comprising a first portion and a second portion, the soft anchor positioned between the first portion and the second portion, the first portion being threaded through the second portion to form a saddle positioned on the first portion, wherein said deploying leaves the saddle spaced a distance from the soft anchor along the flexible member;

tensioning the second portion, after said deploying, so as to draw the flexible member through the soft anchor and move the saddle toward the soft anchor along the flexible member and into abutment with the soft anchor in the bore, wherein the saddle compresses the soft anchor within the bore, deforming the soft anchor and resisting the flexible member from slideably moving relative to the soft anchor; and

threading the flexible member through a soft tissue to secure the soft tissue to the bone.

9. The method of claim 8 further comprising fixing a secondary anchor to the bone.

10. The method of claim 9 further comprising fixing an end of the flexible member to the secondary anchor to secure the soft tissue to the bone without forming any knots between the soft anchor and the secondary anchor.

11. The method of claim 10 further comprising creating a web of flexible members to secure the soft tissue to the bone by implanting a plurality of suture constructs and secondary anchors.

12. The method of claim 11, wherein the suture constructs are knotless suture constructs.

13. The method of claim 8, wherein the bone is a humerus and the soft tissue is a rotator cuff.

14. The method of claim 8 further comprising aligning a guide tool on an outer surface of the bone to form the bore in the bone.

15. The method of claim 8, wherein said tensioning moves the saddle into the bore from a location outside the bore.

16. A method for coupling tissue, comprising:

forming a bore in a humerus;

deploying a soft anchor of a non-slip suture construct into the bore;

adjusting a saddle of the non-slip suture construct along a flexible member of the non-slip suture construct, after said deploying, so as to move the saddle toward the soft anchor along the flexible member and into abutment with the soft anchor in the bore, wherein the saddle resists the flexible member from slideably moving relative to the soft anchor;

threading the flexible member around or through a rotator cuff to draw the rotator cuff to the humerus;

tensioning the flexible member on a top side of the rotator cuff;

affixing the tensioned flexible member to a lateral row anchor to secure the rotator cuff to the humerus; and

forming a web of knotless non-slip suture constructs on the top side of the rotator cuff by inserting a plurality of non-slip suture constructs along a medial row, threading a plurality of flexible members through the rotator cuff, and affixing the plurality of flexible members to at least one lateral row anchor.

17. The method of claim 16 further comprising aligning a guide tool on an outer surface of the humerus to form the bore in the humerus.

18. The method of claim 16, wherein the flexible member includes a first portion and a second portion, wherein the first portion is threaded through the second portion to form the saddle.

19. The method of claim 18, wherein the saddle compresses the soft anchor within the bore, deforming the soft anchor.

20. The method of claim 16, wherein said adjusting leaves the saddle flush with an outer surface of the humerus.

21. The method of claim 16, wherein the flexible member is threaded around or through the rotator cuff and affixed to the lateral row anchor without forming any knots between the soft anchor and the lateral row anchor.
