Abstract
An improved cage that has an anchoring system and method of use thereof. The anchoring system has movable/expandable jaw portions that can expand vertically (i.e., upward and downward relative to the respective superior and inferior surfaces of the cage) so that the cage can be more securely implanted in position. The superior and inferior expandable portions of the anchoring system move vertically by the rotation of one or more spindles that is incorporated in the jaw mechanism (and/or by the rotation of a lead screw that is incorporated in the cage). In some embodiments, the medical implant (such as a cage) is itself non-expandable (i.e., the height of the medical implant does not change). In other embodiments, the medical implant (such as a cage) can be expanded independently of the anchoring system.
