  • Artificial intervertebral disc
    Patent number: 6626943
    Abstract: The invention relates to an artificial intervertebral disc for implantation between two vertebral bodies (W) comprising two end plates (1, 2) and an elastically deformable disc (3) pre-stressed between the end plates (1, 2) in the axial direction, with the disc (3) lying within a tubular, elastically deformable, fibre ring (4) and the end plates (1, 2) being in tensile communication with the fibre ring (4). The disc (3) has a contact surface (5, 6) which enlarges with a compression of the artificial intervertebral disc and which adjoins one of the end plates (1, 2) so that the elastic properties of the artificial intervertebral disc show a non-linear behaviour with increasing deformation at least with respect to a compression force (F).
