CA 2757837

In an embodiment, a system for treating the spine includes a catheter (101) having an elongated shaft with a proximal end adapter, a distal end releasably engaging an expandable interspinous process spacer device (900), and a longitudinal axis therebetween, wherein an inner void of the catheter (101) is sufficiently designed for passage of a liquid light-curable material to the interspinous process spacer device (900), wherein an inner lumen of the catheter (101) is sufficiently designed for passage of a light-conducting fiber to the interspinous process spacer device (900), wherein the interspinous process spacer device (900) includes a circumferential groove (930), wherein the interspinous process spacer device (900) is sufficiently designed to inflate and deflate as the liquid light-curable material is added, and wherein the interspinous process spacer device (900), when positioned between two spinous processes (980) and inflated, is configured to engage the spinous processes (980) at the groove (930).

Cette invention concerne un système de traitement du rachis comprenant un cathéter (101) comportant une tige allongée équipée d'un embout terminal proximal, d'une extrémité distale s'introduisant de manière amovible dans un dispositif étirable d'écartement de processus interépineux (900), et d'un axe longitudinal entre les deux, l'espace vide interne du cathéter (101) étant conçu pour laisser passer un matériau liquide durcissable jusqu'au dispositif d'écartement de processus interépineux (900), la lumière du cathéter (101) étant conçue pour laisser passer une fibre conductrice de lumière jusqu'au dispositif d'écartement de processus interépineux (900), ledit dispositif d'écartement (900) comprenant une rainure circonférentielle (930), ledit dispositif d'écartement (900) étant conçu pour gonfler et dégonfler au fur et à mesure de l'introduction du matériau liquide durcissable, et ledit dispositif d'écartement (900), une fois placé entre deux processus épineux (980) et gonflé, est conçu pour introduire le processus épineux (980) au niveau de la rainure (930).
