Patent ID: 8740981

Claim:
A nuclear implant that forms, between the vertebral endplates of overlying and underlying vertebrae of a spine segment, an intervertebral support device, the implant comprising a single continuous wire capable of being arranged inside a nuclear space that is obtained after nucleotomy of an intervertebral disc, the single continuous wire capable of coiling inside the nuclear space and forming a stacked outer coil that is configured to span the nuclear space, the outer coil having a winding axis in a first direction that is normal to the vertebrae of the spine segment, an outer surface of the outer coil being configured to be concentrically located adjacent to an inner wall of the nuclear space; and the single continuous wire further capable of coiling inside the nuclear space and forming a plurality of stacked inner coils arranged inside the outer coil, a first inner coil having a winding axis in a second direction that is opposite to the first direction, an outer surface of the first inner coil being concentrically located adjacent to an inner surface of the outer coil, the outer surface of each additional inner coil of the plurality of inner coils being concentrically located adjacent to the inner surface of a preceding inner coil, and each additional inner coil having a winding axis in a direction that is opposite of the preceding inner coil, wherein the plurality of inner coils define a central space inside the implant, and the outer coil and the plurality of inner coils are configured to span the intervertebral disc between the two endplates.
