1. A microwave ablation catheter system, comprising:
a microwave ablation catheter configured for navigation within airways of a patient;
a distal handle including a longitudinal through passage configured to receive the microwave ablation catheter;
a proximal handle slidably disposed within the longitudinal through passage of the distal handle such that the distal handle is movable over the proximal handle;
a locking mechanism coupled to the distal handle and configured to prevent movement of the distal handle relative to the proximal handle; and
an engagement interface extending from the distal handle and configured to releasably attach the distal handle to a navigation catheter configured to receive the microwave ablation catheter for placement of the microwave ablation catheter at a target within the patient.
