Abstract

An anchoring device having an elongate body at a proximal portion, a distal portion of the elongate body forming a loop at a distal portion of the anchoring device, and a pledget placed over the elongate body adjacent a proximal portion of the loop. The loop further includes a plurality of anchors disposed along a surface thereof and the loop. Methods for securing anchoring devices of the present disclosure are also disclosed.

First claim

What we claim is:

1. A medical device comprising:
an elongate body having a proximal portion, a distal portion, and a plurality of barbs disposed along the proximal portion of the elongate body, 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 first plurality of 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.

2. The medical device of claim 1 , wherein the plurality of barbs are oriented toward the loop.

3. The medical device of claim 1 , wherein the plurality of barbs are a combination of large barbs and small barbs.

4. The medical device of claim 1 , 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.

5. The medical device of 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 a body tissue.

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

7. The medical device of claim 1 , further comprising a needle secured to the free end of the proximal portion of the elongate body.

8. The medical device of claim 1 , wherein the pledget is disposed in abutment with the proximal portion of the loop.

9. The medical device of claim 1 , 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.

10. A method for securing tissue, the method comprising:
providing the medical device of claim 1 ,
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.

11. The medical device of claim 1 , wherein the proximal portion of the elongate body is of sufficient length for suturing a wound.

12. A medical device comprising:
an elongate body having a proximal portion, a distal portion, and a plurality of barbs disposed along the proximal portion of the elongate body, 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.

13. The medical device of claim 12 , wherein the plurality of barbs are oriented toward the loop.

14. The medical device of claim 12 , wherein the plurality of barbs are a combination of large barbs and small barbs.

15. The medical device of claim 12 , 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.

16. The medical device of claim 12 , wherein the pledget is a separate device which is placed over the elongate body adjacent the proximal portion of the loop.

17. The medical device of claim 12 , 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.

18. The medical device of claim 12 , wherein the pledget engages tissue to prevent movement of the loop in a proximal direction.

19. The medical device of claim 12 , further comprising a needle secured to the free end of the proximal portion of the elongate body.

20. The medical device of claim 12 , wherein the pledget is disposed in abutment with the proximal portion of the loop.

21. A method for securing tissue, the method comprising the steps of
providing the medical device of claim 12 ,
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.

22. The medical device of claim 12 , wherein the proximal portion of the elongate body is of sufficient length for suturing a wound.
