摘要： A system is for thermal ablation and includes (a) a heating element heating an ablation fluid flowing through an ablation device and to a target region of a body and (b) a computing arrangement controlling power supplied to the heating element supplying power to heat the ablation fluid to a desired temperature. The computing arrangement reduces the supplied power when a detected ablation fluid temperature exceeds a desired temperature and increases the supplied power when the detected ablation fluid temperature is below the desired temperature. The computing arrangement monitors a percentage of heat supplied by the heating arrangement to heat the fluid to the desired temperature as a function of a maximum amount of heat which the heating element is capable of supplying.
