Abstract

L'invention concerne un système pour effectuer une cryo-ablation d'un tissu cible sur un site de traitement, comprenant un élément cryogénique fixé à l'extrémité distale d'un cathéter cryogénique. Un ballon de forme annulaire est fixé à un manchon de forme cylindrique et ledit manchon est monté de manière à pouvoir coulisser sur le cathéter cryogénique. L'extrémité distale d'un tube de remplissage est fixé au manchon, ce qui permet de placer la lumière du tube de remplissage en communication fluidique avec le ballon. Lors de l'utilisation, l'élément cryogénique est positionné en premier sur le site de traitement au moyen du cathéter cryogénique. Puis, le tube de remplissage est utilisé pour avancer le ballon et le manchon sur le cathéter cryogénique, jusqu'à ce que le ballon soit interposé entre l'élément cryogénique et le tissu cible. Une solution saline est ensuite pompée à travers le tube de remplissage, ce qui permet l'expansion du ballon entre l'élément cryogénique et le tissu cible. Un produit réfrigérant est ensuite introduit dans l'élément cryogénique, et congèle la solution saline, ce qui permet la réalisation la cryo-ablation du tissu cible.
