Title (EN) MULTI-COMPOSITE DISC PROSTHESIS
(FR) PROTHESE DE DISQUE MULTI-COMPOSITE
Abstract:
(EN) 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.
(FR) La présente invention porte sur une prothèse de disque multi-composite prévue pour être implantée dans l'annulus d'un espace central de disque évidé d'un rachis humain. La prothèse de disque comprend un corps unitaire globalement solide d'une taille et d'une dimension adaptées pour être positionnées dans l'annulus de l'espace central de disque évidé. Le corps présente une partie externe constituée d'un premier biomatériau et une partie interne constituée d'un deuxième biomatériau. Le deuxième biomatériau présente un module d'élasticité en compression qui est plus dur que le module d'élasticité en compression du premier biomatériau, lesdits premier et deuxième biomatériaux étant chimiquement ou physiquement liés pour former un matériau multi-composite qui forme le corps solide.
