1. A method to non-thermally ablate tissue to treat a lung disease, comprising:
advancing a guide sheath to a first treatment zone in a lung of a patient;
operatively coupling an expandable electrode to a generator, wherein the electrode comprises a deployed state and a collapsed state;
operatively coupling a second electrode to the generator;
expanding the electrode from the compressed state to the deployed state at the first treatment zone;
activating the generator programmed to generate a first set of bipolar electrical pulses configured to be delivered through the deployed electrode to the first treatment zone, wherein the bipolar electrical pulses are configured to result in non-thermal ablation of tissue in the first treatment zone;
collapsing the deployed electrode to the collapsed state;
withdrawing the electrode while in the collapsed state back into the guide sheath;
advancing the guide sheath and the collapsed electrode to a second treatment zone in the lung;
expanding the electrode the deployed state at the second treatment zone;
reactivating the generator programmed to generate a second set of bipolar electrical pulses configured to be delivered through the deployed electrode to the second treatment zone, wherein the bipolar electrical pulses are configured to result in non-thermal ablation of tissue in the second treatment zone.
