Abstract
Abstract An arthroscopic method and apparatus for implanting a suture fixation device or other appliance into tissue using a hollow cannulated grasper. Tissue at a repair site is secured with a hollow grasper. Suture material is appended to a suture anchor. The suture anchor or other appliance is attached to a device driver and installed through the hollow grasper into the repair site, where it is drilled into bone.
