The application discloses a kind of frozen ablation catheter and its working method, comprising: frozen probe, first channel and second channel being communicated with frozen probe;Wherein, to form the shunt channel of first channel and second channel between first channel and second channel, shunt channel forms shunt inlet at first channel, and shunt channel forms shunt outlet at second channel;When refrigerant enters second channel from first channel through shunt channel, local low pressure is formed at shunt outlet.The application carries out different degrees of shunt in advance to high-speed flowing refrigerant, uses the local low pressure area formed by the entrainment phenomenon generated by high-speed fluid to determine whether the balloon of frozen probe exists breakage leakage by monitoring the pressure change in catheter.
