This invention aims to obviate the unevenness of a balloon surface temperature of the ablation catheter with a balloon for cauterizing a tissue with an attempt to improve the healing effect by ablation. This invention provides an agitating method for agitating a heating liquid by vibration in a ablation catheter with a balloon comprising: a catheter shaft a balloon installed on the catheter shaft a lumen extending through the catheter shaft in a long axial direction and communicating with the interior of the balloon a heating electrode disposed inside the lumen a heating device applying electrical energy on the heating electrode and a vibrating device periodically repeating the suction and drain of the heating liquid from the lumen and vibrating the heating liquid, the vibration is performed in such a manner that for each drain, the value of the volume of the heating liquid discharging to the balloon each time divided by the expanding volume of the balloon and timing 100 is 2~9.本發明之目的在於,消除用來燒灼組織之帶有氣球之電燒導管的氣球表面溫度的溫度偏差,改善電燒的治療效果。本發明提供一種攪拌方法,係在帶有氣球之電燒導管系統中,藉由振動對加熱用液體進行攪拌的攪拌方法,其中該帶有氣球之電燒導管系統具備:導管軸;氣球,其安裝於導管軸上;導管腔,其於長軸方向貫通導管軸且與氣球內部連通;加熱電極,其配置於氣球內部;加熱裝置,其對加熱電極施加電能;及振動施加裝置,其周期性地從導管腔反復進行加熱用液體之抽吸與吐出而對加熱用液體施加振動;該振動係使以氣球之膨脹體積除以朝向該氣球一次吐出之加熱用液體的一次吐出量的體積並乘以100而得的值成為2~9的方式被施加。1...帶有氣球之電燒導管2a...導管軸3...氣球4...導管腔5...側孔6...振動施加裝置7...三方活栓8...耐壓延長管9...加熱電極10...溫度感測器11...加熱電極用引線12...溫度感測器用引線13...加熱裝置15...帶有氣球之電燒導管系統
