An intervertebral disc device is provided comprising a distal sheath (914) sized to be extended from a distal end of an introducer (912) that is percutaneously delivered into an interior of an intervertebral disc, a distal section of the sheath (918) being predisposed to adopting a bent configuration when extended from the introducer; a probe (916) adapted to be extended from a distal end of the sheath, the bent section of the sheath (918) causing the probe (916) to adopt a same bent configuration; and a proximal handled for externally guiding the probe within an intervertebral disc.

L'invention concerne un dispositif pour disque intervertébral comprenant une gaine (914) distale dimensionnée de manière à pouvoir avancer à partir de l'extrémité distale d'un introducteur (912) introduit à l'intérieur d'un disque intervertébral par voie percutanée. Une section distale de la gaine (918) tend à adopter une configuration incurvée lorsqu'elle est avancée hors de l'introducteur. Ce dispositif comprend en outre une sonde (916) conçue pour être sortir de l'extrémité distale de la gaine, la section incurvée de la gaine (918) conduisant la sonde (916) à adopter une configuration incurvée similaire, et un manche proximal permettant de guidage externe de la sonde dans le disque intervertébral.
