Abstract

A suture including a loop having a tapered surface is provided. The suture includes an elongate body including a proximal portion and a distal portion, wherein the distal portion includes first and second overlapping sections and a loop. A proximal end of the first overlapping section may be tapered with respect to a longitudinal axis of the elongate body. The first overlapping section may be secured to the second overlapping section proximal of the loop. The overlapping sections may be secured together by at least one method selected from the group consisting of glues, adhesives, epoxies, solvents, heat and ultrasonic energy.

First claim

What is claimed is:

1. A method of using a looped suture including a tapered surface, the method comprising:
providing a suture including an elongate body, and a loop formed from a distal portion of the elongate body, wherein a section of the elongate body is secured to an overlapping section of the elongate body to form the loop, wherein a proximal end of the overlapping section is tapered;
inserting a proximal portion of the elongate body into tissue;
pulling the elongate body through the tissue until the tapered overlapping section engages the tissue;
continuing pulling the elongate body through the tissue such that the tapered overlapping section is at least partially received within the tissue.

2. The method of claim 1 , further including inserting the proximal portion of the elongate body through the loop.

3. The method of claim 2 , further including tensioning the proximal portion of the elongate body through the loop until the tissue is retained within the suture.

4. The method of claim 1 , wherein the suture includes a needle on the proximal portion of the elongate body.

5. The method of claim 1 , further including forming a knot in the suture.

6. The method of claim 5 , wherein forming the knot includes tying the knot near the proximal end of the elongate body to retain the proximal portion of the elongate body through the loop.

7. The method of claim 5 , wherein forming the knot includes tying the proximal portion of the elongate body to the loop.

8. The method of claim 1 , wherein the tapered proximal end is generally linear.

9. The method of claim 1 , wherein the tapered proximal end is generally curved.

10. The method of claim 9 , wherein the curve is convex.

11. The method of claim 9 , wherein the curve is concave.

12. The method of claim 1 , wherein the tapered proximal end angles downward towards a longitudinal axis of the elongate body.

13. The method of claim 12 , wherein the tapered proximal end forms an angle of about zero degrees (0°) to about ninety degrees (90°) relative to the longitudinal axis of the elongate body.

14. The method of claim 13 , where the tapered proximal end forms an angle of about five degrees (5°) to about sixty degrees (60°).

15. The method of claim 1 , wherein the loop is sized and dimensioned to receive the proximal end of the elongate body.

16. The method of claim 1 , wherein the loop is sized and dimensioned to receive a surgical needle.

17. The method of claim 1 , wherein the elongate body includes barbs on at least a portion thereof.

18. The method of claim 1 , wherein the loop includes barbs on at least a portion thereof.

19. The method of claim 1 , wherein the tapered proximal end is configured to penetrate tissue.

20. The method of claim 1 , wherein each of the section of elongate body and the overlapping section of the elongate body define a longitudinal axis, the longitudinal axis of the section of elongate body and the longitudinal axis of the overlapping section are parallel.
