A device for delivering energy to an airway of a lung, the device comprising: an elongate member including a proximal end, a distal end, and a lumen extending therebetween； an actuating member operably coupled to the proximal end； an electrode assembly operably coupled to the distal end, wherein the electrode assembly includes a plurality of electrodes； and an operating member extending from the actuating member, through the lumen of the elongate member, and coupled to a distal end of the electrode assembly, wherein the operating member is configured to move reciprocally relative to the elongate member via actuation of the actuating member, wherein reciprocal movement of the operating member is configured to transition the electrode assembly between a first configuration and a second configuration, and wherein the operating member is biased distally by a resilient member in the actuating member.
