Patent ID: 7686807

Claim:
A method of fixing a first piece of bone to a second piece of bone comprising the steps of: providing a pin having at least one laterally moveable distal anchor and a lumen extending therethrough; advancing the distal anchor through the first piece of bone and into the second piece of bone while the distal anchor is permitted to move laterally inwardly as needed; gripping with a deployment tool a proximal portion of a wire that extends axially through the lumen; and proximally retracting with the deployment tool the wire axially through the lumen such that a distal portion of the wire resists radial inward deflection of the distal anchor, thereby locking the distal anchor with respect to lateral inward movement; wherein the step of proximally retracting with the deployment tool the wire axially through the lumen comprises moving an outer body of the deployment tool with respect to a central body of the deployment, tool; and wherein the step of moving the outer body of the deployment tool with respect to the central body of the deployment tool comprises one way ratchet-type motion.
