Anchoring device
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. The loop further includes a plurality of anchors disposed along a surface thereof and the loop also including an end effector. Methods for securing anchoring devices of the present disclosure are also disclosed.
1. A method for securing tissue, the method comprising:
providing a suture having a proximal portion and a distal portion, wherein the proximal portion includes a single elongate body and the distal portion of the suture includes a loop, wherein at least a portion of the loop includes a first plurality of barbs extending in a distal direction and a second plurality of barbs extending in a proximal direction, the suture further includes a transition area defined by a bifurcation of the single elongate body into two branches of the loop;
inserting the proximal portion of the suture into tissue at a penetration point;
advancing the two branches of the suture through the tissue such that the two branches are simultaneously pulled through the penetration point;
pulling the suture through tissue until movement of the loop through the tissue is limited by the second plurality of barbs; and,
securing the suture in the tissue.
2. The method according to claim 1 , wherein advancing the two branches of the suture through the penetration point increases the holding force of the suture in the tissue.
3. The method according to claim 1 , wherein the two branches exert pressure on the tissue at the penetration point.
4. The method according to claim 1 , wherein the second plurality of barbs limits movement of at least a portion of the loop through the tissue such that a segment of the loop remains outside the tissue.
5. The method according to claim 1 , wherein the second plurality of barbs engages the tissue to prevent movement of the loop in a proximal direction.
6. The method according to claim 1 , wherein the first plurality of barbs are disposed on a surface of the two branches of the suture.
7. The method according to claim 6 , wherein the first plurality of barbs secure the two branches in the tissue.
8. The method according to claim 1 , wherein inserting the proximal portion of the suture into the tissue at the penetration point includes directing a needle disposed on a free end of the single elongate body into the tissue at the penetration point.
9. A method for securing tissue, the method comprising:
providing a suture having a single elongate body and a loop disposed on a distal end of the elongate body, the loop including a proximal portion and a distal portion, wherein the proximal portion includes a first plurality of barbs extending towards the distal portion and the distal portion includes a second plurality of barbs extending towards the proximal portion;
inserting the single elongate body of the suture into tissue at a penetration point;
advancing the proximal portion of the loop through the penetration point; and,
pulling the suture through tissue until movement of the loop through the tissue is limited by the second plurality of barbs.
10. The method according to claim 9 , wherein inserting the single elongate body of the suture into the tissue at the penetration point includes directing a needle disposed on a proximal end of the single elongate body of the suture into the tissue at the penetration point.
