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:
a flexible fixation member comprising a body having two terminal ends;
a suture passing through the fixation member along a length of the body between the two terminal ends such that portions of the fixation member are slidable relative to the suture and configurable to form an anchor within a bone hole; and
a delivery device comprising an elongated member including a forked distal end and a finger-engageable assembly coupled to a proximal end, the forked distal end configured to receive the portions of the fixation member and the suture therein;
wherein the finger-engageable assembly includes a groove defined about an entirety of a circumference of the finger-engageable assembly for retaining a portion of the suture therein; and
wherein the fixation member is configured to form the anchor within the bone hole when the suture is tensioned against the distal end of the elongated member while the elongated member is inserted into the bone hole.

2. The surgical assembly of claim 1 , wherein the anchor is in the form of a cluster or bunch including a number of folds.

3. The surgical assembly of claim 1 , wherein the portion of the fixation member received within the forked distal end comprises a general u-shape to allow the fixation member to bend around the forked distal end.

4. The surgical assembly of claim 1 , wherein at least one of the fixation member and the suture comprises a bioactive material.

5. The surgical assembly of claim 1 , wherein at least one of the fixation member and the suture comprise a size 2 suture.

6. The surgical assembly of claim 1 , further comprising a cannula configured to allow passage of the delivery device therethrough.

7. The surgical assembly of claim 6 , wherein a distal portion of the cannula comprises a serrated edge for facilitating maintenance of the cannula on bone.

8. The surgical assembly of claim 6 , wherein a distal portion of the cannula is angled relative to a longitudinal axis of the cannula, and at least a portion of the delivery device is flexible to permit the delivery device to conform to a shape of the cannula.
