The present invention relates to a heat exchange balloon assembly (11) for cooling the oesophagus during heat ablation treatment to the heart comprising an inflatable balloon (4) adapted for insertion into the oesophagus, provided with an exterior heat-transfer surface and a lumen within said inflatable balloon (4) adapted to carry thermal exchange medium configured such that said heat-transfer surface conducts thermal energy between oesophagus and said lumen. The invention also relates to a heat exchange balloon assembly (11) connected to a temperature controller provided with a means to receive data pertinent to the power supplied to an ablation probe and/or the temperature of the tip of the ablation probe. It further relates to an ablation system implementing the invention, and to a method.
La présente invention concerne un ensemble ballonnet à échange thermique (11) destiné à refroidir l~oesophage lors d~un traitement par ablation thermique sur le coeur comprenant un ballonnet gonflable (4) conçu pour une insertion dans l~oesophage, équipé d~une surface de transfert thermique externe et d~une lumière à l'intérieur dudit ballonnet gonflable (4) conçu pour porter un support d~échange thermique configuré de telle sorte que ladite surface de transfert thermique conduit l~énergie thermique entre l~oesophage et ladite lumière. L~invention concerne également un ensemble ballonnet d~échange thermique (11) raccordé à un dispositif de commande de la température équipé d~un moyen pour recevoir des données pertinentes par rapport à l~énergie fournie à une sonde d~ablation et/ou la température à la pointe de la sonde d~ablation. Elle concerne en outre un système d~ablation mettant en oeuvre l~invention, ainsi qu~un procédé.
