Claim Text:
1. A stirring method for stirring a liquid for heating by a vibration, the method comprising: providing an ablation catheter system with a balloon, the ablation catheter system comprising a catheter shaft, the balloon fixed to the catheter shaft, the balloon having a film thickness of 20 μm to 100 μm, a lumen passing through the catheter shaft in a direction of a longitudinal axis to communicate with an interior of the balloon, a heating electrode arranged in the interior of the balloon, a heating device, and a vibration imparting device; applying with the heating device an electric energy to the heating electrode; imparting with the vibration imparting device a vibration to a liquid for heating by periodically repeating suction and ejection of the liquid for heating from the lumen; and wherein the vibration is imparted to the liquid for heating so that a value derived by dividing a volume of the liquid for heating to be ejected from the lumen toward the balloon at a single time by an expansion volume of the balloon and multiplying the quotient by 100 becomes 2 to 9 and the imparting with the vibration imparting device repeats the suction and the ejection of the liquid for heating 1 to 5 times per second.
