Abstract
An intervertebral implant includes a chassis and endplates movable relative to the chassis. The endplates are each movable between a contracted position, wherein the endplates are nearer to a central axis defined relative to the chassis, and an expanded position, wherein the endplates are farther from the central axis. The chassis includes at least one wedge that, in turn, includes surfaces along which the endplates travel in transition between the contracted and expanded positions. The wedge remains stationary relative to the central axis throughout transitions between the contracted and expanded positions.
