Title
(EN) SYSTEMS FOR TEMPERATURE CONTROL IN DELIVERY OF THERMAL LIQUID TREATMENT
(FR) SYSTÈMES DE RÉGULATION DE TEMPÉRATURE LORS DE L'ADMINISTRATION D'UN TRAITEMENT THERMIQUE LIQUIDE
Abstract
(EN) A heated liquid system may comprise a catheter including a liquid delivery channel for delivery of a treatment liquid from a distal end portion of the catheter. The catheter may also include a circulation supply channel extending along the liquid delivery channel. The circulation supply channel may be configured to convey a heated liquid from a heated liquid source toward the distal end portion of the catheter. The catheter may also include a circulation return channel extending along the liquid delivery channel. The circulation return channel may be configured to convey the heated liquid from the distal end portion toward a proximal end portion of the catheter. The heated liquid may be used to maintain a temperature of the treatment liquid.
(FR) Système de liquide chauffé pouvant comprendre un cathéter comprenant un canal de distribution de liquide pour l'administration d'un liquide de traitement à partir d'une partie d'extrémité distale du cathéter. Le cathéter peut également comprendre un canal d'alimentation en circulation s'étendant le long du canal de distribution de liquide. Le canal d'alimentation en circulation peut être configuré pour transporter un liquide chauffé depuis une source de liquide chauffé vers la partie d'extrémité distale du cathéter. Le cathéter peut également comprendre un canal de retour de circulation s'étendant le long du canal de distribution de liquide. Le canal de retour de circulation peut être configuré pour transporter le liquide chauffé de la partie d'extrémité distale vers une partie d'extrémité proximale du cathéter. Le liquide chauffé peut être utilisé pour maintenir une température du liquide de traitement.
