Patent ID: 8906095

Claim:
A disc implant, comprising: a first inter-vertebral element defining a first inner face that includes a first central region and the first inter-vertebral element defining a first outer face; and a second inter-vertebral element defining a second inner face that includes a second central region and the second inter-vertebral element defining a second outer face; wherein the first and second inner faces of the first and second inter-vertebral elements are adapted to be positioned in a facing alignment; wherein the first and second outer faces of the first and second inter-vertebral elements are adapted to be positioned facing away from each other and configured to be placed adjacent to respective vertebra of a vertebral column of a patient; wherein the first central region defines a first profile configured to be placed in a medial-lateral direction relative to the vertebral column of the patient that is defined by a single arc and a second profile configured to be placed in an anterior-posterior direction relative to the vertebral column of the patient that (i) extends from an anterior edge of the first central region to a posterior edge of the first central region, and (ii) is defined by at least two arcs; and wherein the second central region defines a first profile configured to be placed in a medial-lateral direction relative to the vertebral column of the patient that is defined by a single arc and a second profile configured to be placed in an anterior-posterior direction relative to the vertebral column of the patient that (i) extends from an anterior edge of the second central region to a posterior edge of the second central region, and (ii) is defined by a linear line.
