Ablation catheter system with balloon and control method thereof

The invention relates to a method and system for estimating cautery depth when a balloon ablation catheter system is ablated. An ablation catheter system is provided with: a catheter shaft; a balloon attached to the catheter shaft; a lumen passing through the catheter shaft in the longitudinal direction and communicating with the inside of the balloon; a heating electrode and a temperature sensor disposed inside the balloon; a heating device for applying electric energy to the heating electrode; a pressure sensor; a balloon volume sensor; and a processor that calculates an estimated depth of cauterization using, as variables, the heating temperature of the generator, the cauterization time of the generator, the value of the balloon pressure obtained from the pressure sensor, and the value of the balloon volume obtained from the balloon volume sensor. 本发明涉及一种用于在带球囊的消融导管系统进行消融时估计烧灼深度的方法和系统。本发明提供一种消融导管系统，具备：导管轴；球囊，其安装于上述导管轴；管腔，其沿长轴方向贯通上述导管轴并与上述球囊内部连通；配置于上述球囊内部的加热电极及温度传感器；加热装置，其对上述加热电极施加电能；压力传感器；球囊体积传感器；以及处理器，其将发
