Abstract
A biocompatible surgical fastener, comprising a sleeve and a screw or a pin, which expands when it is implanted in a patient. The sleeve is first implanted in a pre-drilled hole in the operating area of a patient, usually in a bone, cartilage or a bone and cartilage. When a screw or a pin is installed in the sleeve, the sleeve is caused to expand thereby stabilizing the fastener in the operating area. In many embodiments the screw or pin can be removed and reinserted without disturbing the tissue in the operating area. The surgical fastener can be used to repair tissue or to secure other implant devices in a patient.
