An intervertebral disc is expanded and injected by forming and dilating an opening in the disc annulus and introducing an inflatable member into the disc nucleus pulposus. The inflatable member location within the nucleus pulposus is verified and the inflatable member is gradually inflated for augmenting a space in the nucleus pulposus. The internal pressure and expansion of the inflatable member are monitored. The inflatable member is subsequently deflated and a biomaterial is injected into the augmented space.
Selon cette invention, on peut étendre un disque intervertébral et effectuer une injection dans ce disque au moyen d'une méthode consistant à former et à dilater une ouverture dans l'annulus du disque puis à introduire un élément gonflable dans le noyau pulpeux du disque. La méthode consiste ensuite à vérifier la position de l'élément gonflable dans le noyau pulpeux puis à gonfler progressivement l'élément gonflable afin qu'un espace soit élargi dans ledit noyau pulpeux. La pression interne et l'extension de l'élément gonflable sont surveillées. L'élément gonflable est ensuite dégonflé et un biomatériau est injecté dans l'espace élargi.
