Abstract
A multi-material spinal interbody device includes an inner dampener of compressible material in combination with a rigid outer material. The rigidity of the outer periphery of curved surfaces of the device, such as in an eluipsoid shape, provide support as a replacement to the nucleus propulsus, with the inner dampener providing for absorption of spinal forces.
