Abstract

Dans une forme d'exécution, un appareil comprend une canule configurée pour procurer un accès percutané à un noyau d'un disque intervertébral, et un corps allongé configuré de manière à pouvoir être disposé dans une lumière de la canule. La canule définit également une ouverture. Le corps allongé définit un passage interne et une ouverture à une portion distale du corps allongé. Le passage interne du corps allongé peut être couplé avec une source d'aspiration. Le corps allongé présente une portion de coupe, prévue sur un bord de l'ouverture dudit corps allongé, et le corps allongé est configuré pour tirer une portion d'un tissu de l'intérieur du noyau du disque intervertébral dans l'ouverture du corps allongé, lorsque la source d'aspiration est activée. La portion de coupe est configurée pour séparer la portion de tissu du tissu restant lorsque le corps allongé est déplacé par rapport à la canule.
