  • Multi-composite disc prosthesis
    Patent number: 8038718
    Abstract: A multi-composite disc prosthesis is adapted to be implanted within the annulus of an evacuated disc nucleus space in a human spine. The disc prosthesis has a generally solid unitary body with a size and a shape adapted to be positioned within the annulus of the evacuated disc nucleus space. The body has an outer portion comprised of a first biomaterial and an inner portion comprised of a second biomaterial. The second biomaterial has a compressive modulus that is harder than a compressive modulus of the first biomaterial and the first and second biomaterials are chemically or physically bonded to form a multi-composite material that forms the solid body.
