| 摘要 |
The present invention relates to a heat exchange balloon assembly (11) for cooling the oesophagus during heat ablation treatment to the heart comprisin g an inflatable balloon (4) adapted for insertion into the oesophagus, provide d with an exterior heat-transfer surface and a lumen within said inflatable balloon (4) adapted to carry thermal exchange medium configured such that sa id 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.
