Title
(EN) MINIMALLY INVASIVE EXPANDING SPACER AND METHOD
(FR) DISPOSITIF D'ESPACEMENT MINI-INVASIF ET PROCEDE
Abstract
(EN)
A minimaly invasive spacer for positioning between vertebral members. The spacer is adjustable between a first orientation having a reduced size to facilitate insertion between the vertebral members. A second orientation has an enlarged size for contacting the vertebral members. The spacer includes linkages that are attached to a pair of plates. A pull arm is operatively connected to the linkages for adjusting the spacer from the first orientation to the second orientation. A delivery device is attached to the spacer for insertion between the vertebral members. In one embodiment, the delivery device is detachable to be removed from the spacer once positioned between the vertebral members. Method of using the spacer include positioning the spacer between the vertebral members while in the first orientation. The spacer is then enlarged to the second orientation, and the delivery device is removed with only the spacer remaining within the patient.

L'invention concerne un dispositif d'espacement mini-invasif destiné à être positionné entre les vertèbres. Le dispositif d'espacement peut être ajusté entre une première orientation de taille réduite pour faciliter son insertion entre les vertèbres. Une deuxième orientation a une plus grande taille pour venir en contact avec les vertèbres. Le dispositif d'espacement inclut des liaisons qui sont attachées à une paire de plaques. Un bras de traction est connecté fonctionnellement aux liaisons pour ajuster le dispositif d'espacement entre la première orientation et la deuxième orientation. Un dispositif d'installation est fixé au dispositif d'espacement pour permettre son insertion entre les vertèbres. Dans un mode de réalisation, le dispositif d'installation peut être détaché afin d'être enlevé du dispositif d'espacement une fois que ce dernier est positionné entre les vertèbres. L'invention concerne aussi un procédé d'utilisation du dispositif d'espacement qui inclut le positionnement du dispositif d'espacement entre les vertèbres lorsqu'il est dans la première orientation. Le dispositif d'espacement est ensuite agrandi dans la deuxième orientation, et le dispositif d'installation est enlevé, seul le dispositif d'espacement restant en place dans le patient.
