Abstract

The invention relates to an apparatus which is used to cool part of the oesophagus in order to prevent injury thereto owing to overheating during a hyperthermal ablation procedure close to the oesophagus. The inventive apparatus comprises a flexible element (1, 11) which is configured to be inserted into the patient's mouth or nose and which has one part that is intended to be placed in contact with the oesophagus. The aforementioned flexible element comprises a coolant circulation circuit which is configured such that the coolant circulates through the part that is intended to be placed in contact with the oesophagus. The flexible element can be connected to a coolant-pumping device (7, 17) and is equipped with temperature-detection means. The invention also relates to an associated method.
