Patent ID: 8187332

Claim:
A bone fusion device for insertion between bones comprising: a. a body comprising first and second ends and an exterior surface having one or more channels; b. an interior cavity deposed between the first and second ends; c. a conduit providing a pathway from the interior cavity to the exterior surface; d. one or more tabs for bracing the bone fusion device in a space between the bones, each tab comprising a first tab end proximate the first end and a second tab end distal from the first end and proximate the second end; e. a positioning element positioned through the first end and substantially within the interior cavity having an aperture configured to permit an engaging member of a tool to rotate the positioning element; and f. a plurality of extending blocks coupled to the positioning element and in contact with the one or more tabs for moving the one or more tabs, wherein as the positioning element moves the plurality of extending blocks from a compact position to an extended position, the tabs are raised towards an extended position with the extending blocks directly supporting the first tab end and the second tab end when in the extended position; wherein the channels are each positioned along the exterior surface on a plane perpendicular to the aperture of the positioning element such that one or more supporting members of the tool are able to enter the one or more channels by moving along the plane thereby securing the engaging member of the tool within the aperture, and further wherein the exterior surface faces away from the interior cavity.
