Paclitaxel-Coated Pulmonary Balloon for the Treatment of Benign Central Airway Stenosis

The OXYGEN-RCT trial is a randomized, controlled, double blinded, prospective, multi-center trial to demonstrate the safety and efficacy in adult benign central airway stenosis. Participates will be in a 1:1 allocation to treatment with the Airiver Pulmonary DCB or standard of care laryngoscopic/bronchoscopic balloon dilation, respectively.

To Investigate Airway Oxygen Concentrations During Rigid Bronchoscopy Procedures Performed With High Frequency Jet Ventilation

Thermal ablation (use of treatment modalities that generate heat) has become a widely used tool for treatment of central airway obstruction (e.g. laser, electrocautery, radiofrequency, and argon plasma coagulation). However, this method carries with it an increased risk for airway fire - a surgical fire that occurs in a patient's airway and could also include a fire in the attached breathing circuit. To decrease the risk of airway fire during mechanical ventilation with an endotracheal tube, the concentration of inspired oxygen (FiO2) is set below 40% while waiting for end tidal oxygen concentration (EtO2) to fall below 40% prior to starting thermal ablation. There is no published literature describing O2 concentration within the airways (AiO2) during jet ventilation with rigid bronchoscopy. The co-investigators of this study have recently collected data on AiO2 during rigid bronchoscopy using manual low frequency jet ventilation/high frequency jet ventilation with a period of apnea. The intent of this study is to measure the time taken for the central airway oxygen concentration to drop from 90 to 40% when the "laser mode" is activated on the Monsoon jet ventilator. Ventilation is continued during "laser mode."

Paclitaxel-Coated Pulmonary Balloon for the Treatment of Benign Airway Stenosis

The goal of this Prospective Trial of Paclitaxel-Coated Pulmonary Balloon for the Treatment of Benign Airway Obstruction (OXYGEN-1) is to evaluate clinical safety and potential efficacy of the Airiver Pulmonary DCB in the treatment of benign central airway stenosis.

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

This research is being done to evaluate the feasibility of the AveCure Flexible Microwave destruction of tissue (Ablation) Probe for the treatment of malignant central airway obstruction using a thin, tube-like instrument with a light and a lens for viewing and removing tissue (bronchoscopic). The name of the intervention being used in this research study is: AveCure Flexible Microwave Ablation Probe (handheld, surgical device that delivers microwave energy via flexible probe tip)
