The microwave ablation catheter is inserted into the extended working channel (EWC) (first “click”), and locked to the bronchoscope system using a long rod (second “click”). Afterwards, the ablation catheter is unsheathed by pulling the EWC backwards, with the operator’s left hand holding the ablation catheter steady and right hand pulling the EWC backwards in a slow and controlled fashion. The third “click” signifies complete unsheathing of the ablation catheter.
