(FR) PROCEDE ET DISPOSITIF D'ANESTHESIE
Abstract:
(EN) The present invention provides apparatus and methods for introducing spinal anesthesia directly into the subarachnoid space of a patient. One apparatus and method utilizes a small gauge spinal needle for penetrating the dura; the other utilizes a small gauge catheter (32) with an internal stylet having a non-piercing pencil point (36) to spread apart the filaments of the dura wall. An introducer (12) having a rounded tip (20) is also provided for guiding and supporting the spinal needle or catheter, as force is applied thereto, to cause the same to penetrate the dura.
(FR) La présente invention se rapporte à des procédés et dispositif d'administration d'une anesthésie spinale directement dans l'espace subarachnoïde d'un patient. L'un des procédés et dispositif utilise une aiguille spinale de petit gabarit pour pénétrer dans la paroi durale; l'autre utilise un cathéter (32) de petit gabarit à stylet interne (34) possédant une pointe non aiguisée (36) pour séparer les filaments de la paroi durale. Un introducteur (12) à extrémité arrondie (20) est également prévu pour guider et soutenir l'aiguille spinale ou le cathéter, quand une force leur est appliquée, pour les faire pénétrer dans la paroi durale.
