Abstract:
The present invention provides a next generation, closed profile, total disc replacement device with mechanical features designed to sustain, restrain and guide the larger motions required to preserve normal mechanical motion, while at the same time, providing a flexion component to guide and restrain the finer motions reached at the extremes of the mechanical motion preservation components.

Claim (Index 1):
A device comprising:\n a. a top endplate comprising a top surface for engaging with the underside of a superior vertebral body and a bottom surface engaged in a ball and socket configuration with a top dome portion of a nucleus to form a first joint of defined, and mechanically constrained, ranges of motion inherently enforced by the joint structure; b. a nucleus comprising a top convexly curvate dome portion, a core portion connecting said curvate top dome portion to a substantially planar bottom \u201cfoot\u201d portion, and a bottom foot portion, wherein said nucleus including its dome, core and foot, are either unitary or are connected to each other to form a unitary nucleus and wherein said dome of said nucleus is retained in contact with a mating curvate top endplate undersurface, such that said first joint is a closed-profile joint; and c. a bottom endplate translationally engaged with said bottom foot portion of said nucleus to form a second joint of defined, and mechanically constrained, ranges of motion, wherein said foot of said nucleus is retained within a cavity in said bottom endplate in connection with which it is translationally engaged, such that said second joint is a closed profile joint, wherein said first joint and said second joint, in concert, when implanted into an intervertebral space, comprise a closed profile of two joints which are constrained by the resulting mechanical structure to facilitate substantially physiologically acceptable rotational, lateral and flexural motions, when compared with a biological disc in the spine of a recipient which said device is implanted to replace.
