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 flexible fixation member at various points along a length of the body between the terminal ends such that at least a portion of the fixation member is slidable relative to the suture and configurable to form an anchor within a surgical site; and
a delivery device comprising:
a handle;
a tubular member coupled to the handle;
an elongated inserter slidably disposed within the tubular member, the inserter comprising a forked distal end, the forked distal end configured to receive a portion of the flexible fixation member and the suture therein; and
a finger-engageable trigger coupled to the handle and the proximal end of the inserter, the finger-engageable trigger configured to advance and retract the inserter relative to the tubular member;

wherein a proximal portion of the suture is disposed within the handle.

2. The surgical assembly of claim 1 , wherein the suture comprises a size 2 suture.

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

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

5. The surgical assembly of claim 1 , wherein the flexible fixation member comprises suture, tape, braid or mesh.

6. The surgical assembly of claim 1 , wherein the tubular member and the inserter are dimensioned such that a portion of the suture extending proximally from the flexible fixation member is routable through the tubular member concurrently with the inserter without being compressed.

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

8. A method of tissue repair, comprising:
delivering a surgical assembly to a surgical site, the surgical assembly comprising:
a flexible fixation member comprising a body having two terminal ends;
a suture passing through the flexible fixation member at various points along a length of the body between the terminal ends such that at least a portion of the fixation member is slidable relative to the suture and configurable to form an anchor within the surgical site; and
a delivery device comprising:
a handle;
a tubular member coupled to the handle;
an elongated inserter slidably disposed within the tubular member, the inserter comprising a forked distal end, the forked distal end configured to receive a portion of the flexible fixation member and the suture therein; and
a finger-engageable trigger coupled to the handle and the proximal end of the inserter, the finger-engageable trigger configured to advance and retract the inserter relative to the tubular member;

wherein a proximal portion of the suture is disposed within the handle,
advancing the inserter to position the flexible fixation member within the surgical site;
tensioning the suture to cause the flexible fixation member to form the anchor within the surgical site; and
retracting the inserter proximally relative to the tubular member to remove the forked distal end of the inserter from within the surgical site.

9. The method of claim 8 , wherein the suture comprises a size 2 suture.

10. The method of claim 9 , wherein the anchor is in the form of a cluster or bunch including a plurality of folds.

11. The method of claim 9 , wherein the portion of the flexible fixation member received within the forked distal end comprises a general u-shape to allow the flexible fixation member to bend around the forked distal end.

12. The method of claim 9 , wherein the flexible fixation member comprises suture, tape, braid or mesh.

13. The method of claim 9 , wherein the tubular member and the inserter are dimensioned such that a portion of the suture extending proximally from the flexible fixation member is routable through the tubular member concurrently with the inserter without being compressed.

14. The method of claim 9 , wherein at least one of the fixation member and the suture comprises a bioactive material.
