Patent ID: 8419796

Claim:
An intervertebral prosthetic device comprising: a first lateral component sized and shaped for lateral insertion through a disc space between an upper vertebra and a lower vertebra from a first lateral side of a patient and into engagement with a lateral sidewall of at least one of the upper and lower vertebra on a second lateral side of the patient opposite the first lateral side; a second lateral component sized and shaped for lateral insertion from the first lateral side of the patient and into engagement with a lateral sidewall of at least one of the upper and lower vertebra on the first lateral side of the patient; an elongated member extending between and connected to each of the first lateral component and the second lateral component, the elongated member sized to extend across the disc space between the upper vertebra and the lower vertebra when the first lateral component is engaged with the lateral sidewall of at least one of the upper and lower vertebra on the second lateral side of the patient and the second lateral component is engaged with the lateral sidewall of at least one of the upper and lower vertebra on the first lateral side of the patient; and a central component directly engaged with the elongated member and positioned between the first lateral component and the second lateral component, the central component sized and shaped for positioning in the disc space between the upper vertebra and the lower vertebra; wherein the first lateral component includes a central portion positioned between two end portions, the central portion formed of a first material and the two end portions formed of a second material different than the first material, the first material being resiliently flexible and the second material being more rigid than the first material.
