1. A microwave ablation system comprising:
a microwave energy source;
a microwave ablation catheter for treating tissue, the microwave ablation catheter receiving microwave energy from the microwave energy source and having an inner conductor, an outer conductor, and a balun electrically coupled to the outer conductor;
a guide catheter configured to navigate a patient's airways, the guide catheter including a tool lumen configured to receive the microwave ablation catheter for positioning of the microwave ablation catheter adjacent a target within the patient's lungs;
a probe disposed on the guide catheter for facilitating navigation of the guide catheter within the patient's airways;
a locatable guide configured to be inserted through the tool lumen of the guide catheter while the guide catheter is navigated within the patient's airways; and
an electromagnetic position sensor disposed on a distal tip portion of the locatable guide for electromagnetically tracking a position of the distal tip portion within the patient's airways, the electromagnetic position sensor configured to project from a distal tip of the guide catheter during use of the locatable guide while navigating the guide catheter and the locatable guide within the patient's airways, wherein the locatable guide is configured to be removed from the tool lumen after navigation of the guide catheter and the locatable guide adjacent the target and the microwave ablation catheter is configured to be inserted through the tool lumen and positioned adjacent the target after removal of the locatable guide from the tool lumen.
