Microwave ablation system

Abstract

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