Expanding suture anchor having an actuator pin

A suture anchor system for anchoring soft tissue to bone, the suture anchor system comprising:

• a suture anchor including a sleeve anchor and a suture-receiving insert, the sleeve anchor including a distal end opening and a proximal end opening, the sleeve anchor further including an interior side wall and exterior threads, the suture-receiving insert including a distal portion and a proximal body portion that extends proximally of the distal portion, the distal portion including a distal tip and a proximal end with a proximal facing surface;
• and
• a suture passable through an eyelet in the suture-receiving insert and couplable to soft tissue,
• wherein the suture-receiving insert is partially receivable in the sleeve anchor to lock the suture to the suture anchor, said partially receivable including the proximal body portion extending into the sleeve anchor through the distal end opening in the sleeve anchor with the distal portion remaining outside the sleeve anchor distal of the distal end opening, wherein the sleeve anchor includes a distal facing surface around the distal end opening, and wherein the suture being so locked includes the suture extending from a first free end of the suture that is positioned inside the sleeve anchor distally along the proximal body portion between an exterior side wall of the proximal body portion and the interior side wall of the sleeve anchor to exit the sleeve anchor through the distal end opening without ever passing through the proximal end opening in the sleeve anchor, followed by the suture exiting and subsequently re-entering the suture anchor by passing a first time and a second time, respectively, between the proximal facing surface of the proximal end of the distal portion and the distal facing surface of the sleeve anchor without passing through the sleeve anchor, followed by the suture passing through the eyelet in the suture-receiving insert, followed by the suture re-exiting the suture anchor by passing a third time between the proximal facing surface of the proximal end of the distal portion and the distal facing surface of the distal end of the sleeve anchor, wherein the first free end of the suture is fixedly coupled to the suture-receiving insert independent of the sleeve anchor.
