1. A method of knotless tissue fixation, comprising the steps of:
- attaching a first flexible strand to tissue to be fixated;
preloading a cannulated interference device on a driver shaft;
forming an eyelet loop that is removably attached to the driver shaft by passing a second flexible strand through a plurality of lateral through-holes provided within opposing arms of a forked tip provided at a most distal end of the driver shaft and releasably attached to the driver shaft, wherein the cannulated interference device is disposed proximal to the forked tip on the driver shaft;
passing the first flexible strand through the removably attached eyelet loop;
subsequently, decreasing a size of the eyelet loop to force the first flexible strand into the forked tip and to secure the first flexible strand between the opposing arms of the forked tip; and
securing the first flexible strand into a bone socket.

Abstract
Techniques and reconstruction systems for knotless tissue fixation using a driver with a cannulated interference device or fixation device preloaded on the shaft of the driver. An eyelet, adjustable in size, is formed of a loading suture provided at the distal end of the driver shaft. A working suture attached to the tissue to be fixed is passed through the eyelet. The size of the eyelet is adjusted by the user once the working suture is passed through the eyelet, to capture the working suture with the eyelet. The cannulated interference device is then advanced down the shaft to secure the working suture in a bone socket.

4. A method of soft tissue repair, comprising the steps of:
-
providing a hole in a bone at a location at which a soft tissue graft is to be affixed; attaching at least one suture to the soft tissue graft to be affixed; preloading a cannulated interference device on a shaft of a driver; forming an eyelet loop that is removably attached to a distal end of the shaft by passing a flexible strand through a plurality of lateral through-holes formed on opposing arms of a forked tip that is releasably attached to the driver shaft, the eyelet loop having an adjustable perimeter, wherein the cannulated interference devices is disposed proximal to the forked tip on the driver shaft; capturing the suture attached to the graft between the opposing arms of the forked tip by feeding the suture through the eyelet loop; inserting the suture into the hole by inserting the distal end of the driver into the hole; pulling on one end of the suture to draw the suture through the eyelet loop such that the soft tissue graft attached to the suture is drawn toward the hole; and inserting the interference device into the hole so that the cannulated interference device is advanced toward the suture, to secure the suture in the hole. - View Dependent Claims (5, 6, 7, 8)
