Title
(EN) CRYOGENIC CATHETER SYSTEM
(FR) SYSTEME DE CATHETER CRYOGENIQUE
Abstract
(EN)
A cryogenic catheter system provides safe and effective treatment of tissue. The system includes a catheter that is coupled to a console via fluid and electrical umbilicals. The console controls the overall operation of the system based to provide and maintain a predetermined temperature at the catheter tip. The console also controls and monitors operating parameters for providing warning indications to the user and terminating operation of the system in the event of a failure that may compromise patient safety.

Système de cathéter cryogénique qui permet un traitement sûr et efficace des tissus. Ledit système comporte un cathéter qui est couplé à une console via des liaisons ombilicales pour fluide et électriques. La console permet la commande du fonctionnement global du système, de manière à fournir et à maintenir une température prédéterminée à l'extrémité du cathéter. Ladite console permet également la commande et la surveillance des paramètres de fonctionnement, de façon à fournir des indications à l'utilisateur et à arrêter le fonctionnement du système en cas de défaillance pouvant compromettre la sécurité du patient.
