Abstract

Finger traps for collapsible suture loops are provided. In general, a suture coupled to an implant can be tensioned to facilitate desirable positioning of the implant relative to tissue in a patient's body. The suture can include a finger trap and a knot. In general, the finger trap is a hollow area of the suture through which the suture passes through itself and is configured to slide in a single direction when under tension. In an exemplary embodiment, the knot is located along a length of the suture that is closer than the finger trap to a tail of the suture that is being pulled to tension the suture.

First claim

What is claimed is:

1. A surgical device, comprising:
a first implantable anchor;
a second implantable anchor; and
a suture coupled to the first and second anchors, the suture having a first length extending from the first anchor toward the second anchor and having a second length extending from the second anchor toward the first anchor, the first length having a knot formed therein, wherein the knot is selected from the group consisting of an overhand knot, a hitch knot, a bend knot, a static knot, a sliding knot, and a collapsing knot, and the second length passing through a hollow portion formed in a body of the suture and then passing through the knot with a tail of the suture extending from the knot, the hollow portion being formed in the first length and being the only hollow portion in the body of the suture.

2. The device of claim 1 , wherein the tail of the suture is configured to be pulled in a first direction toward the first anchor to tension the suture, and is configured to be pulled in a second, different direction to tension the suture.

3. The device of claim 2 , wherein pulling the tail of the suture in the first direction is configured to reduce a distance between the first and second anchors, and pulling the tail of the suture in the second direction is configured to reduce the distance between the first and second anchors.

4. The device of claim 2 , wherein pulling the tail of the suture in the first direction is configured to cause the suture to slide within the hollow portion and through the knot, and pulling the tail of the suture in the second direction is configured to cause the suture to slide within the hollow portion and through the knot.

5. The device of claim 2 , wherein the suture is slidable through the hollow portion in only the first direction.

6. The device of claim 1 , wherein the second length exits the hollow portion before passing through the knot.

7. The device of claim 1 , wherein the first anchor has a first hole through which the suture extends, and the second anchor has a second hole through which the suture extends.

8. The device of claim 1 , further comprising a second suture coupled to the second anchor and having the suture looped therethrough so as to couple the suture to the second anchor.

9. The device of claim 1 , wherein the suture is braided from a plurality of threads.

10. A surgical device, comprising:
a first implantable anchor;
a second implantable anchor;
a first suture attached to the first anchor, the first suture including a hollow portion through which another portion of the first suture passes through, a knot being adjacent to the hollow portion such that a tail of the first suture passes through the hollow portion and then passes through the knot, the tail being configured to be pulled to slide the first suture through the hollow portion and through the knot; wherein the knot is selected from a group consisting of an overhand knot, a hitch knot, a bend knot, a static knot, a sliding knot, and a collapsing knot; and
a second suture attached to the second anchor, the second suture defining a loop through which the first suture passes.

11. The device of claim 10 , wherein the tail is configured to be pulled in any direction to slide the first suture through the hollow portion and through the knot.

12. The device of claim 10 , wherein the hollow portion and the knot are located along a length of first suture extending between the first and second anchors.

13. The device of claim 10 , wherein pulling the tail to slide the first suture through the hollow portion and through the knot reduces a distance between the first and second anchors.

14. The device of claim 10 , wherein the first suture defines an adjustable loop, the adjustable loop passes through the loop defined by the second suture, and pulling the tail to slide the first suture through the hollow portion and through the knot collapses the adjustable loop.

15. A surgical method, comprising:
advancing a suture, a first anchor, and a second anchor into a body of a patient with the suture extending between the first and second anchors, having a knot formed therein, wherein the knot is selected from a group consisting of an overhand knot, a hitch knot, a bend knot, a static knot, a sliding knot, and a collapsing knot, and having a hollow portion adjacent the knot through which another portion of the suture extends; and
advancing each of the first and second anchors through a soft tissue and then, with the suture extending through the tissue and between the first and second anchors, tensioning the suture to cause the suture to slide through the knot and through the hollow portion and cause the first and second anchors to move relative to the tissue.

16. The method of claim 15 , wherein the suture is uni-directionally slidable through the hollow portion in a first direction, and tensioning the suture includes pulling a tail of the suture extending from the knot in the first direction.

17. The method of claim 15 , wherein the suture is uni-directionally slidable through the hollow portion in a first direction, and tensioning the suture includes pulling a tail of the suture extending from the knot in a second, different direction.

18. The method of claim 15 , wherein the tissue is at one of a knee, a hip, and a shoulder of the patient.
