Title (EN) METHODS AND APPARATUS FOR TREATING INTERVERTEBRAL DISCS
(FR) METHODES ET APPAREIL DE TRAITEMENT DES DISQUES INTERVERTEBRAUX
Abstract:
(EN) Apparatus and methods for treating a target tissue by delivering a fluid at a defined temperature to a patient's body. An apparatus of the invention includes a fluid delivery unit for delivering fluid in at least close proximity to the target tissue, an aspiration unit for withdrawing the fluid, and a fluid source unit (21) for providing the fluid (50) at the defined temperature. A method of the invention includes forming a void in at least close proximity to the target tissue, and circulating a preheated fluid through the void, wherein the target tissue undergoes adjustment from body temperature due to heat exchange between the fluid and the target tissue.
(FR) Cette invention concerne un appareil et des méthodes de traitement de tissus cibles par administration dans le corps du patient d'un fluide à une température définie. L'appareil selon l'invention comprend une unité de distribution de fluide permettant d'amener un liquide à proximité du tissu cible, une unité d'aspiration servant à évacuer ce fluide, et une unité d'alimentation pour la fourniture du fluide à la température voulue. Une méthode selon l'invention consiste à former un vide au moins à proximité du tissu cible, à faire circuler un fluide préchauffé dans ce vide, ce qui a pour effet de faire passer le tissu cible de la température du corps à la température de traitement par suite de l'échange de chaleur entre le fluide et le tissu cible.
