Patent ID: 8496689

Claim:
A spinal implant device for placement between adjacent spinous processes and adjacent a thecal sac, the spinous processes including a superior spinous process extending to a superior spinolaminar junction and an inferior spinous process extending to the inferior spinolaminar junction, the spinous processes disposed about a pair of opposing facet joints, the spinal implant device comprising: a fusion cage including: a superficial face defining an interspinous surface; a deep face defining a thecal sac surface disposable adjacent the thecal sac; a superior saddle portion defining a superior interlaminar fusion surface disposed between the superficial and deep faces, the superior saddle portion sized and configured to receive the superior spinolaminar junction; an inferior saddle portion defining an inferior interlaminar fusion surface disposed between the superficial and deep faces, the inferior saddle portion sized and configured to receive the inferior spinolaminar junction; and opposing cage ends, each cage end defining a facet fusion surface disposed between the superior and inferior interlaminar fusion surfaces, the facet fusion surfaces sized and configured to respectively contact the opposing facet joints; first and second fixation plates each having a superior end and an inferior end, the first and second fixation plates each being sized and configured to extend along the adjacent spinous processes with the superior ends disposed about and in contact with the superior spinous process and the inferior ends disposed about and in contact with the inferior spinous process: and a connector extending from the superficial face and connected to the first and second fixation plates.
