Bone fusion device, system and method

A method of implanting a bone fusion device into a desired location, the method comprising:

• providing a bone fusion device, the bone fusion device including a body having an interior cavity that houses a positioning element, a lock including a collar positioned around one end of the positioning element and a choke positioned around the collar, one or more tabs each having an inner surface and a support rib, and one or more extending blocks each having a rib slot, wherein the positioning element is coupled with the extending blocks;
• inserting the bone fusion device in the desired location;
• extending the one or more tabs from a retracted position within the interior cavity to an extended position at least partially outside the interior cavity by moving at least one of the plurality of extending blocks along the inner surface of the tabs such that the rib slots slide along the support ribs positioned at least partially within the rib slots;
• and
• locking the positioning element in place by rotating the choke until the choke causes the collar to constrict around the positioning element thereby impeding rotation of the positioning element.

A method of using a bone fusion device, the method comprising:

• securing a gripping apparatus to the bone fusion device by inserting one or more fingers of the gripping apparatus into one or more channels on an exterior surface of a body of the bone fusion device;
• providing the bone fusion device to a desired location, wherein the bone fusion device comprises the body having an interior cavity that houses a perimeter of each of one or more tabs, each tab of the tabs having an inner surface and a support rib, and one or more extending blocks each having a rib slot and an external surface configured to abut a portion of the inner surface of a respective tab, wherein an angle with respect to a common direction formed by the portion of the inner surface of the respective tab that abuts the external surface of the respective block is incongruent with an angle with respect to the common direction formed by an internally facing surface of the support rib that faces a bottom surface of the respective rib slot;
• and
• extending the one or more tabs in an extension direction from a retracted position to an extended position at least partially outside the interior cavity, wherein the rib slot of each of the extending blocks has a plurality of sidewalls substantially parallel to the extension direction, and further wherein each portion of the body remains fixed in place with respect to each other portion of the body during the extending of the one or more tabs.
