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 8):
The device according to  claim 1  wherein:\n a. said top endplate comprises a Ring-Joint-Stop assembled about a middle portion of said nucleus of lower diameter than said top portion of said nucleus, such that following said assembly about said nucleus, said Ring-Joint-Stop is assembled with said top endplate to define a raceway within which said nucleus top portion is rotationally retained; \n b. said bottom endplate comprises a nucleus lower portion retention plate which is assembled about a portion of said nucleus narrower than an orifice defined through said retention plate, when assembled and affixed to said bottom endplate, but which is too narrow for said nucleus lower portion to pass through such that said nucleus lower portion is retained within a cavity defined within said bottom endplate; \n c. axial rotation of said second joint realized by the allowed relative motion between the foot surface and bottom endplate surface of the nucleus is unrestricted regardless of the position of the nucleus foot within said cavity in said bottom endplate, and wherein boundaries dictated by an opening in retainer the bottom endplate nucleus retainer and cavity form an enclosing cavity within which the nucleus foot and, hence, the entire integrated nucleus translates and axially rotates; \n d. spherical mating of the nucleus dome and a mating concavity provided on the underside of the top endplate does not allow translational motion, and wherein flexibility of the nucleus permits y-axis compression-extension, such that, during compression of the nucleus, all three elements of the nucleus, dome, core, and foot have space into which they expand, such that relative rigidity of the top endplate forces the expanded dome to retain the shape of a spherical section; \n e. x-z axis translations of the top endplate and the spherically mated nucleus dome occurs in concert; and \n f. combinations thereof.
