Abstract:
1. An intervertebral implant sized to be implanted between a lower endplate of an upper vertebra and an upper endplate of an adjacent lower vertebra, the implant comprising: (a) an upper closing plate having an external surface configured to contact the lower endplate of the upper vertebra and an opposing inner surface; (b) a lower closing plate having an external surface configured to contact the upper endplate of the lower vertebra and an opposing inner surface; (c) a top cover plate joined to the upper closing plate, the top cover plate including a top, outer surface and an opposing bottom, inner surface, wherein the outer surface of the top cover plate faces the inner surface of the upper closing plate; (d) a bottom cover plate joined to the lower closing plate, the bottom cover plate including a bottom, outer surface and an opposing top, inner surface, wherein the outer surface of the bottom cover plate faces the inner surface of the lower closing plate; (e) a deformable body located between the top and bottom cover plates having a first side wall located between the inner surfaces of the bottom and top cover plates, wherein the deformable body is a separate part from the top cover plate and the bottom cover plate; and (f) a continuous, uninterrupted fiber wound along a fiber path that extends sequentially (1) from beneath the inner surface of the top cover plate and (2) over a portion of the outer surface of the top cover plate between the inner surface of the upper closing plate and the outer surface of the top cover plate and (3) back past the inner surface of the top cover plate and (4) traversing the first side wall and (5) past the inner surface of the bottom cover plate and (6) over a portion of the outer surface of the bottom cover plate between the inner surface of the lower closing plate and the outer surface of the bottom cover plate and (7) back past the inner surface of the bottom cover plate and (8) traversing the first side wall and again (9) passing from beneath the inner surface of the top cover plate and (10) over a portion of the outer surface of the top cover plate between the inner surface of the upper closing plate and the outer surface of the top cover plate and (11) back past the inner surface of the top cover plate; wherein the continuous, uninterrupted fiber is located entirely between the inner surfaces of the upper and lower closing plates.
