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 3):
The device according to  claim 2  further comprising a feature selected from the group consisting of:\n i. the device is assembled by either a snap-fit or a non-snap-fit method for associating the device components to each other; \n ii. the device further comprises a sheath surrounding said nucleus; \n iii. said first joint comprises said top endplate which comprises a Ring-Joint-Stop (RJS) unitary with or assembled to become unitary with said top endplate, wherein said Ring-Joint-Stop either:\n a. comprises an orifice and a raceway, such that said top dome portion of said nucleus snap-fits through said orifice for rotational retention within said raceway; or \n b. an orifice and raceway are defined about the core portion of said nucleus and, once assembled thereabout, retains said dome portion from traversing through said orifice for rotational retention within said raceway; \n \n iv. wherein said bottom endplate comprises a nucleus lower foot portion retention plate unitary with or assembled to become unitary with said bottom endplate, wherein said retention plate either:\n a. comprises an orifice through which said nucleus lower portion is snap-fit for retention within a cavity defined within said bottom endplate; or \n b. is assembled about a core portion of said nucleus to comprise an orifice with sufficiently small diameter that the bottom foot portion of said nucleus cannot traverse through said orifice; \n \n v. at least one cushion ring which interacts with the Ring-Joint-Stop to protect the RJS and retainer plate from impingement damage that would be caused by rotations exceeding their Range-of-Motion (ROM), by resisting further motion once the RJS contacts a cushion ring; \n vi. said nucleus top dome portion comprises a substantially convex top surface shaped to lubriciously mate with the underside of said top endplate and a bottom surface shaped to lubriciously and translationally mate with said bottom endplate such that said top and bottom endplates, once mated with said resilient nucleus, requires super-physiologic force to disengage from each other; and \n vii. combinations thereof.
