Feasibility of the AveCure Microwave Ablation Technology for the Bronchoscopic Treatment of Malignant Central Airway Obstructions

Inclusion Criteria: * Patients age between 18 and 80 years of age and able to provide informed consent. * Candidate for bronchoscopy under general anesthesia. * Diagnosis of central airway obstruction (trachea, right main stem bronchus, left main stem bronchus), as evidenced by CT or CT/PET imaging confirmed or suspected to be due to malignant etiology, for which the bronchoscopist has deemed that endoscopic ablation/debridement is indicated (i.e. endobronchial tumors, mixed endobronchial/extrinsic compression lesions). Exclusion Criteria: * Patients who are unable to understand the informed consent, including potential risks and benefits of the procedure. * Patients in whom bronchoscopy under general anesthesia is contraindicated. * Any comorbidity that the investigator feels would interfere with the safety of the subject or the evaluation of study objectives * Pacemaker, implantable cardioverter, or another electronic implantable device * Patients with coagulopathy * Patients in other therapeutic lung cancer studies * COVID-19 positive patient at the time of the procedure. * Patients who are pregnant * Patients with purely extrinsic compression of the airway.
