1. A method for treating lung tissue of a patient, comprising:

  • generating a pathway to a point of interest in a lung of a patient;

    advancing an extended working channel trans-orally into the lung and along the pathway to the point of interest;

    positioning the extended working channel in a substantially fixed orientation at the point of interest;

    advancing a microwave ablation catheter through the extended working channel to the point of interest, the microwave ablation catheter having a coaxial cable connected at the proximal end of the coaxial cable to a microwave energy source and at the distal end of the coaxial cable to a distal radiating section, the coaxial cable including inner and outer conductors and a dielectric positioned therebetween, the inner conductor extending distally past the outer conductor and in sealed engagement with the distal radiating section; and

    treating the lung tissue at the point of interest.
