Abstract

Claims (30)

1. A method for securing a suture to a bone, comprising:

inserting a soft anchor into a bore hole in the bone, the soft anchor including a body and a suture passing through the body in at least one location;

pulling a first portion of the suture in a first direction, wherein the first portion of the suture comprises at least two protrusions spaced apart from each other along the suture; and

pulling a second portion of the suture in a second direction, wherein the second portion of the suture comprises at least two protrusions spaced apart from each other along the suture;

wherein pulling at least one of the first and second portions of the suture through the soft anchor causes at least one of the protrusions to pass through the soft anchor and inhibit motion in an opposite direction to the first portion being pulled in the first direction or the second portion being pulled in the second direction.

2. The method of claim 1 , wherein the soft anchor is inserted into the bore hole in the bone in an insertion direction, and the suture is pulled through the soft anchor such that a direction of tension is in an opposite direction to the insertion direction.

3. The method of claim 1 , wherein the soft anchor comprises a proximal end and a distal end, wherein a proximal opening is positioned at the proximal end and a distal opening is positioned at the distal end, and the suture is pulled through both the proximal and distal openings.

4. The method of claim 3 , wherein the soft anchor is inserted with the distal end leading into the bore hole in the bone.

5. The method of claim 4 , wherein the proximal end of the soft anchor is retained in the same position relative to the bone when the suture is pulled through the proximal and distal openings.

6. The method of claim 3 , wherein the proximal end of the soft anchor translates toward the distal end when the soft anchor is transitioning from a first state to a second state.

7. The method of claim 1 , further comprising passing the suture around or through soft tissue prior to pulling the suture.

8. The method of claim 1 , wherein pulling the first portion of the suture includes decreasing in size a loop configured to surround a tissue, and wherein pulling the first portion of the suture moves at least one protrusion on the first portion of the suture at least partially through a passageway, entirely through the passageway, into a first opening, out a second opening, or any combination thereof.

9. The method of claim 1 , wherein pulling the second portion of the suture includes decreasing in size a loop configured to surround a tissue, and wherein pulling the second portion of the suture moves at least one protrusion on the second portion of the suture at least partially through a passageway, entirely through the passageway, into a first opening, out a second opening, or any combination thereof.

10. The method of claim 1 , wherein pulling at least one of the first and second portions of the suture causes the soft anchor to transition from a first state in which the soft anchor is adapted to be inserted into the bore to a second state in which the soft anchor is secured in the bore hole.

11. The method of claim 10 , wherein transitioning to a second state causes the soft anchor to expand in a plane orthogonal to a direction of inserting the soft anchor.

12. The method of claim 10 , wherein pulling at least one of the first and second portions of the suture causes tensioning of soft tissue, wherein at least some of the tensioning of the soft tissue occurs simultaneous to transitioning the soft anchor from the first state to the second state.

13. A suture fixation system comprising:

a suture comprising:

a first portion including a first suture strand and at least two spaced apart protrusions provided on the first suture strand; and

a second portion including a second suture strand and at least two spaced apart protrusions provided on the second suture strand, wherein with the suture in an elongate position, the protrusions on the first strand face in a direction opposite to the protrusions on the second strand; and

a soft anchor comprising:

a proximal end and a distal end and a connection portion extending therebetween,

wherein the first and second portions of the suture are configured to pass through the soft anchor such that at least one of the protrusions abuts a surface of the soft anchor.

14. The system of claim 13 , wherein the at least two protrusions of the first portion of the suture comprise unidirectional locking devices oriented in a first passing direction.

15. The system of claim 14 , wherein the at least two protrusions of the second portion of the suture comprise unidirectional locking devices oriented in a second passing direction opposite the first passing direction.

16. The system of claim 13 , wherein the soft anchor is ring shaped.

17. The system of claim 13 , wherein the soft anchor is suture woven or braided material.

18. The system of claim 13 , wherein the first and second portions of the suture are configured to pass through the soft anchor to cause the soft anchor to deploy from a first insertion state to a second locking state.

19. The system of claim 18 , wherein the soft anchor has an opening at the proximal end and an opening at the distal end, and the suture is configured to pass through both openings and the protrusions are configured to abut the distal end of the soft anchor to cause the openings to approach each other to deploy the soft anchor from the first insertion state to the second locking state.

20. The system of claim 13 , further comprising an insertion device configured to deliver the soft anchor into a bone and configured to pull the suture through the soft anchor.
