Abstract

An assembly includes a flexible fixation member, a suture, and a delivery device. The fixation member includes a body with two terminal ends. A suture passes through the flexible fixation member at various points along a length of the body such that portions of the fixation member are slidable relative to the suture and configurable to form a cluster within a surgical site. The delivery device includes a tubular member, an elongated inserter, and a trigger. The elongated inserter is slidably disposed within the tubular member. The inserter has a forked distal end configured to receive a portion of the flexible fixation member and the suture. The trigger is finger-engagable and fixedly coupled to the proximal end of the inserter. It is configured to advance and retract the inserter relative to the tubular member. The trigger includes a retention member for retaining a proximal end portion of the suture.

First claim

What is claimed is:

1. A surgical assembly comprising:
an all-suture anchor;
a suture slidably received by the all-suture anchor such that the all-suture anchor can bunch up relative to the suture;
an elongate member including a forked distal end; and
a proximal portion proximal to the elongate member, the proximal portion defining a circular groove;
wherein the all-suture anchor and the suture are received on the forked distal end such that the suture extends proximally along an external surface of the elongate member and through the proximal portion, and wraps around the proximal portion within the circular groove; and
wherein the circular groove is oriented perpendicular to a longitudinal axis of the elongate member.

2. The surgical assembly of claim 1 , wherein the all-suture anchor comprises a flexible body formed by two legs and a U-shaped bend joining the two legs, each of the two legs having a terminal end.

3. The surgical assembly of claim 2 , wherein the suture passes through a plurality of openings in the all-suture anchor along a length of the flexible body between the terminal ends of the two legs.

4. The surgical assembly of claim 3 , wherein the suture only extends a single time through each of the plurality of openings.

5. The surgical assembly of claim 2 , wherein the suture extends longitudinally down one leg of the flexible body and longitudinally up the other leg of the flexible body in a single direction without intersecting itself.

6. The surgical assembly of claim 1 , wherein the all-suture anchor comprises monofilament, tape, braid, or mesh.

7. The surgical assembly of claim 1 , wherein the suture comprises two end regions and an entirety of the suture, including the end regions, is slidable with respect to an entire longitudinal extent of the all-suture anchor in either direction.

8. The surgical assembly of claim 1 , further comprising a cannula configured to allow passage of the forked distal end therethrough.

9. The surgical assembly of claim 8 , wherein a distal portion of the cannula comprises a serrated edge for facilitating maintenance of the cannula on bone.

10. The surgical assembly of claim 9 , wherein a distal portion of the cannula is angled relative to a longitudinal axis of the cannula, and at least a portion of the elongate member is flexible to permit the elongate member to conform to a shape of the cannula.

11. A surgical assembly comprising:
an all-suture anchor;
a suture slidably received by the all-suture anchor such that the all-suture anchor can bunch up relative to the suture;
an elongate member including a forked distal end; and
a proximal portion proximal to the elongate member, the proximal portion defining a circular groove;
wherein the all-suture anchor and the suture are received on the forked distal end such that the suture extends proximally along an external surface of the elongate member and through the proximal portion, and extends perpendicular to the elongate member across a diameter of the surgical assembly to the circular groove.

12. The surgical assembly of claim 11 , wherein the all-suture anchor comprises a flexible body formed by two legs and a U-shaped bend joining the two legs, each of the two legs having a terminal end.

13. The surgical assembly of claim 12 , wherein the suture passes through a plurality of openings in the all-suture anchor along a length of the flexible body between the terminal ends of the two legs.

14. The surgical assembly of claim 13 , wherein the suture only extends a single time through each of the plurality of openings.

15. The surgical assembly of claim 12 , wherein the suture extends longitudinally down one leg of the flexible body and longitudinally up the other leg of the flexible body in a single direction without intersecting itself.

16. The surgical assembly of claim 11 , wherein the suture comprises two end regions and an entirety of the suture, including the end regions, is slidable with respect to an entire longitudinal extent of the all-suture anchor in either direction.

17. The surgical assembly of claim 11 , further comprising a cannula configured to allow passage of the forked distal end therethrough.

18. The surgical assembly of claim 17 , wherein a distal portion of the cannula comprises a serrated edge for facilitating maintenance of the cannula on bone.

19. The surgical assembly of claim 17 , wherein a distal portion of the cannula is angled relative to a longitudinal axis of the cannula, and at least a portion of the elongate member is flexible to permit the elongate member to conform to a shape of the cannula.
