Abstract
Abstract An elongated suture anchor driver having a suture retaining means at its proximal end. The driver receives a suture anchor at its distal tip and has a throughbore for enabling suture attached to the suture anchor to pass through the driver from its distal end to its proximal end. The proximal end of the driver is provided with a channel and a fixed post for guiding the suture exiting from the throughbore into an annular recess. A spring loaded slidable cylindrical sleeve acts against the suture in the recess to frictionally retain the suture, thereby securing the suture anchor and suture within the driver.
