  • Patent number: 5458642
    Abstract: This invention comprises of a synthetic intervertebral disc for implantation in the human body. The disc, in its preferred embodiment, is comprised of disc-shaped plates 11(a&b) joined by springs along the inside of the outer perimeter. The plates have oval-like cutouts in their centers for a compressible polymeric core 12 to protrude from on top and bottom. The polymeric core 12 aids in the fitting of the device between the concave surfaces of two vertebrae. An elastomeric covering 14 encircles the area between the plates and is connected to the plates 11(a&b) on top and bottom to prevent body tissues from interfering with the movement of the springs 13(a-i). The spring system distributes forces acting on the disc between the springs and allows normal movement of the vertebrae during flexion and extension of the spine in any direction.
