Microwave ablation catheter and method of utilizing the same

摘要

A method for treating lung tissue of a patient is provided. A pathway to a point of interest in a lung of a patient is generated. An extended working channel is advanced transorally into the lung and along the pathway to the point of interest. The extended working channel is positioned in a substantially fixed orientation at the point interest. A tool is advanced though the extended working channel to the point of interest. The lung tissue is treated at the point of interest.

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.
