Patent ID: 7785369

Claim:
An artificial intervertebral disk insertable between two adjacent vertebral bodies of a patient, the artificial intervertebral disk comprising: two outer elements, each associated with one of the two vertebral bodies disposed parallel to a first plane; and an intermediate element having an annular closed shape and oval or circular cross-section in a second plane perpendicular to the first plane, at least in sections, in an uncompressed state of the intermediate element, wherein the intermediate element joins the two outer elements in a restricted, articulated manner such that torsional moments and shear forces are transmittable, wherein each of the two outer elements have an annular recess with a concave contour and is joined in a form-fitting manner to the intermediate element at the recess, and wherein the contour is oversized relative to the intermediate element such that a radius of the contour is greater than a radius of the intermediate element and a compression of the intermediate element allows a defined deformation of the intermediate element.
