Provided is a catheter system that is capable of performing a suitable irrigation operation. The catheter system (5) comprises: an ablation catheter (1) having an irrigation mechanism; a power supply unit (32) that supplies electrical power to the ablation catheter (1) during ablation; a fluid supply unit (21) for supplying irrigation fluid to the ablation catheter (1); and a control unit (35). The control unit (35) controls so as to achieve high flowrate operation when the measured power (Pm) during ablation is in a high-power state at or above a threshold power (Pth), and controls so as to achieve low flowrate operation when the measured power (Pm) is in a low-power state below the threshold power (Pth). Furthermore, the control unit (35) quickly switches from low flowrate operation to high flowrate operation upon a transition from the low-power state to the high-power state and, upon a transition from the high-power state to the low-power state, if at the time of transition the low-power state has continued for a first standby time, the control unit (35) switches to low flowrate operation after maintaining high flowrate operation for the first standby time. |
