摘要:
A method for ablating tissue comprising controlling a heating element using a variable phase angle control to heat an ablation fluid to a desired temperature and determining a heating percentage corresponding to a percentage of a maximum available heating power represented by a current level of power supplied to the heating element and, when the heating percentage remains below a threshold level for a predetermined period of time, indicating a flow obstruction condition of the fluid.
