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 10):
The device according to  claim 1  wherein said top endplate comprises or is assembled to comprise a curvate Ring-Joint-Stop comprising:\n i. raised left and right lateral convex cylindrical bearing surfaces which define two angle parameters (\u03b2 1  and \u03b2 2 , respectively), within a Ring-Joint-Stop raceway, generated by rotating curvate surfaces of same or different sizes about an x-axis that passes through the center of curvature of said first joint (ball-and-socket), which dictates the ROM of Right-Left Lateral-Bending angle \u03bc such that \u2212\u03b2 2 \u2264\u03bc\u2264\u03b2 1 ; \n ii. raised posterior and anterior convex cylindrical bearing surfaces which define two angle parameters (\u03b1 1  and \u03b1 2 ) within a Ring-Joint-Stop raceway, generated by rotating curvate surfaces of same or different sizes about a z-axis that passes through the center of curvature of said first joint (ball-and-socket), which dictates the ROM of Flexion-Extension angle \u03bb such that \u2212\u03b1 2 \u2264\u03bb\u2264\u03b1 1 ; and \n iii. four cylindrical bearing surfaces in which at least one surface contacts a curvate nucleus dome lip in a curvate line for any rotation angle outside the ROM of either Flexion-Extension or Lateral-Bending, such that, as the rotation angle increases, contact forces increase; and either \n iva. a Ring-Joint-Stop rim, smoothly integrated with and transitioning between each of said four cylindrical bearing surfaces and four, substantially flat, inner-raceway surfaces, wherein said four substantially flat, inner-raceway surfaces provide strength and stiffness to said Ring-Joint-Stop; or \n ivb. a Ring-Joint-Stop rim, which, with respect to the nucleus x-y-z frame of reference and with all four angle parameters equal the same value \u03b1, that facilitates and limits the ROM of both Flexion-Extension angle (\u03bb) and Lateral Bending angle (\u03bc) within the range \u2212\u03b1\u2264\u03bb, \u03bc\u2264\u03b1, as follows:\n a) it allows any sequence of rotations, that at no time results in an equivalent rotation that would require, as part of its implementation, a rotation about some axis in the x-z plane whose magnitude is greater than \u03b1 degrees; \n b) it permits any sequence of rotations satisfying a), which includes Axial (y-axis) rotations, then such Axial rotations move without constraint, whereas any Axial rotation in a sequence of rotations that does not satisfy condition a), is constrained by the RJS; \n c) it constrains a sequence of rotation motions that does not satisfy condition a) by contacting a cushion ring included in said device so as to protect the RJS and a retainer plate from impingement damage that would be caused by rotations exceeding either Flexion-Extension or Lateral-Bending Ranges-of-Motion (ROMs), and, by resisting further motion once the RJS contacts the cushion ring, such that said engagement of the RJS and cushion ring provides a soft stop with increasing resistance as the angle increases beyond \u03b1 degrees, eventually producing a hard stop; and \n d) it comprises a curvate or conic shaped underside portion which participates in resisting either out-of-range, or near out-of-range rotations through curvate line or linear contact, respectively, with a cushion ring thickness designed for such contact.
