Abstract

A suture anchor driver has an elongated shaft, a handle at a proximal end of the shaft an anchor engagement at a distal end of the shaft and a clutch between the handle and the shaft. The clutch includes a slot for frictionally engaging a suture an engagement with the shaft and an engagement with the handle. The engagement with the shaft and the engagement with the handle are located with respect to one another such that driving torque applied to the handle urges open the slot to release its frictional engagement of the suture.
