Patent ID: 8110003

Claim:
An intervertebral disc prosthesis system for the replacement of a spinal disc to restore normal biomechanical behavior, comprising: at least two prosthetic subunits adapted to replace both an annulus fibrosus and a nucleus pulposus of an intervertebral spinal disc; said prosthetic subunits having a plurality of dehydrateable hydraulic beads encompassed within a fabric constraining envelope, said fabric constraining envelope having an osteoinductive and osteoconductive compound coated on a superior and an inferior surface to promote fixation; a containment membrane external to said plurality of dehydrateable hydraulic beads, said containment membrane regulates the hydration rate of said plurality of dehydrateable hydraulic beads or minimizes the migration of said plurality of dehydrateable hydraulic beads; an osteoinductive and osteoconductive material disposed within interstitial spaces between said dehydrateable hydraulic beads.
