 Aeris has developed a novel bronchoscopic system for achieving the benefits of lung volume reduction without surgery. The Bronchoscopic Lung Volume Reduction BLVR Hydrogel System, a new investigational therapy for emphysema, is intended to reduce lung volume over a period of weeks by collapsing and promoting the remodeling of diseased areas of the lung. The resulting reduction in lung volume is intended to restore a more normal physiological relationship between lung and chest wall, improve breathing and exercise capacity and alleviate symptoms of chronic dyspnea. This study will evaluate the safety and efficacy of the Aeris BLVR System in patients with advanced emphysema.
