Abstract
An intervertebral body fusion device has a wedge body, a cage component with a plurality of deployable spines having end plate penetrating teeth, and a contraction mechanism for drawing the wedge body into the cage component. The device is surgically placed intervertebrally into the spine from an anterior surgical approach. In its final surgically-implanted position, the wedge body is substantially fully drawn within the cage component, resulting in a full deployment of teeth and associated spines into the adjacent end plates of the vertebral bodies, while simultaneously restoring the angle of lordosis to the spine.
