(EN) MODULAR NUCLEUS PULPOSUS PROSTHESIS

Abrégé
(EN) A modular nucleus pulposus prosthesis comprising at least two generally mirror image complimentary disc segments combined to form a generally discoid endoprosthetic disc and to associated tools and methods for replacing the intervertebral disc. The complimentary segments are substantially identical including outer circumferential walls roughly equal to a semi-cirde aligned along concave-convex inner wall inner walls forming a common border and a generally symmetrical discoid congruent structure which is positioned within the annulus of a spinal disc section. Disc segments may include structures to support, position and secure the segments to one another intradiscally. Surgical tools include structures for inserting and aligning disc members together. Also disclosed is a system and method for replacing the nucleus pulposus using the surgical tools adapted for placement and alignment of the disc.
(FR) La présente invention concerne une prothèse modulaire du noyau pulpeux comprenant au moins deux segments de disque généralement complémentaires en termes d'image miroir combinés pour former un disque endoprothétique généralement discoïdal, ainsi que des outils et procédés associés au remplacement des disques intervertébraux. Les segments complémentaires sont essentiellement identiques et comprennent des parois périphériques plus ou moins équivalentes à un demi-cercle aligné le long de parois intérieures concavo-convexes formant une limite commune, ainsi qu'une structure congrue discoïdale généralement symétrique qui est positionnée à l'intérieur de l'anneau d'une coupe de disque vertébral. Les segments de disque peuvent comprendre des structures qui vont soutenir, positionner et arrimer les segments les uns aux autres à l'intérieur du disque. Lesdits outils chirurgicaux comprennent des structures permettant l'introduction et l'alignement entre eux des éléments de disque. L'invention concerne également un système et un procédé de remplacement du noyau pulpeux au moyen des outils chirurgicaux conçus pour la mise en place et l'alignement du disque.
