Abstract

An anchoring device includes an elongate body having a proximal portion and a distal portion. The proximal portion of the elongate body terminates in a free end and the distal portion forms a loop. The loop includes a proximal portion and a distal portion. and further includes a plurality of anchors disposed along a surface thereof. The plurality of anchors are oriented toward the proximal portion of the elongate body to limit movement of the loop through tissue. A pledget is disposed adjacent the proximal portion of the loop. Methods for securing anchoring devices of the present disclosure are also disclosed.

First claim

What we claim is:

1. A method for securing tissue comprising:
providing a suture including:
an elongate body having a proximal portion and a distal portion, the proximal portion of the elongate body terminating in a free end and the distal portion of the elongate body forming a loop, the loop including a proximal portion and a distal portion, and a first plurality of anchors disposed along a surface of the loop, the anchors being oriented toward the proximal portion of the elongate body to limit movement of the loop through tissue; and
a pledget including a separate device which is placed over the elongate body adjacent the proximal portion of the loop;

inserting the proximal portion of the suture into tissue at a penetration point;
advancing the suture through the tissue such that the elongate body is pulled through the penetration point to the pledget; and
securing the suture in the tissue.

2. The method according to claim 1 , further comprising the step of:
inserting the proximal portion of the suture through a segment of the loop remaining outside the body tissue.

3. The method according to claim 1 , further comprising the step of:
pulling the suture through tissue until movement of the loop through tissue is limited by a pledget.

4. The method according to claim 1 , wherein the passage of the elongate body through the penetration point to the pledget increases the holding force of the suture in tissue.

5. The method according to claim 1 , wherein the pledget limits movement of at least a portion of the loop through tissue such that a segment of the loop remains outside the body tissue.

6. The method according to claim 1 , wherein the pledget engages tissue to prevent movement of the loop in a proximal direction.

7. The method according to claim 1 , wherein the pledget is disposed about the elongate body in abutment with a proximal portion of the loop.

8. A medical device comprising:
an elongate body having a proximal portion and a distal portion, the proximal portion of the elongate body terminating in a free end and the distal portion of the elongate body forming a loop, the loop including a proximal portion and a distal portion, and a first plurality of anchors disposed along a surface of the loop, the anchors being oriented toward the proximal portion of the elongate body to limit movement of the loop through tissue; and
a pledget including a separate device which is placed over the elongate body adjacent the proximal portion of the loop.

9. The medical device of claim 8 , wherein the pledget is a disc configured and dimensioned to limit movement of a proximal segment of the loop in a proximal direction through tissue.

10. The medical device of claim 9 , wherein the pledget is about 3 mm in diameter.

11. The medical device of claim 8 , wherein the pledget is integral with the proximal portion of the loop.

12. The medical device of claim 8 , wherein the pledget limits movement of at least a portion of the loop through tissue such that a segment of the loop remains outside a body tissue.

13. The medical device of claim 8 , wherein the pledget engages tissue to prevent movement of the loop in a proximal direction.

14. The medical device of claim 8 , further comprising a needle secured to the free end of the proximal portion of the elongate body.

15. The medical device of claim 8 , wherein the pledget is disposed in abutment with the proximal portion of the loop.

16. A method for securing tissue, the method comprising the steps of
providing the medical device of claim 8 , inserting a proximal portion of the medical device into tissue, pulling the elongate body through tissue, and, advancing the proximal portion of the elongate body through tissue such that the pledget limits movement of the proximal portion of the loop through the tissue.

17. The medical device of claim 8 , wherein the first plurality of anchors is disposed on the proximal portion of the loop, and the distal portion of the loop is free of anchors.

18. A medical device comprising:
an elongate body having a proximal portion and a distal portion, the proximal portion of the elongate body terminating in a free end and the distal portion of the elongate body forming a loop, the loop including a proximal portion and a distal portion, and a first plurality of anchors disposed along a surface of the loop at the proximal portion of the loop, and the distal portion of the loop is free of anchors, the anchors being oriented toward the proximal portion of the elongate body to limit movement of the loop through tissue; and
a pledget disposed adjacent the proximal portion of the loop.

19. The medical device of claim 18 , wherein the pledget is a disc configured and dimensioned to limit movement of a proximal segment of the loop in a proximal direction through tissue.

20. The medical device of claim 19 , wherein the pledget is about 3 mm in diameter.

21. The medical device of claim 18 , wherein the pledget is integral with the proximal portion of the loop.

22. The medical device of claim 18 , wherein the pledget is a separate device which is placed over the elongate body adjacent the proximal portion of the loop.

23. The medical device of claim 18 , wherein the pledget limits movement of at least a portion of the loop through tissue such that a segment of the loop remains outside a body tissue.

24. The medical device of claim 18 , wherein the pledget engages tissue to prevent movement of the loop in a proximal direction.

25. The medical device of claim 18 , further comprising a needle secured to the free end of the proximal portion of the elongate body.

26. The medical device of claim 18 , wherein the pledget is disposed in abutment with the proximal portion of the loop.

27. A method for securing tissue, the method comprising the steps of providing the medical device of claim 18 , inserting a proximal portion of the medical device into tissue, pulling the elongate body through tissue, and,
advancing the proximal portion of the elongate body through tissue such that the pledget limits movement of the proximal portion of the loop through the tissue.
