Abstract (en)
[origin: WO2012146615A1] The invention relates to an intervertebral-disc prosthesis including a structure comprising a rigid upper plate (10), a rigid lower plate (11), and a core (20) inserted between said plates, characterized in that said structure is made from a thermoplastic material, the core further including a thermoplastic monomaterial having graduated elastic and damping properties. According to one alternative embodiment, said core consists of an elastomeric central core (20c, 20ci) surrounded by one or more rings (20p, 20pj), which are referred to as rings having ranks j relative to the core, and which are more rigid.
