Brief summary
This study is designed to demonstrate safety and efficacy in patients with severe upper lobe predominant emphysema. For validity of the study, the results will be compared to patients that receive optimal medical therapy.
Interventions
Patients will be treated with the InterVapor System in 1 to 2 segments in the upper lobes of each lung (2 to 3 segments total). Patients will also receive Optimal Medical Therapy. Guidelines for prescribing medical treatment for emphysema are published by the American Thoracic Society (ATS) and the National Heart Lung and Blood Institute/World Health Organization (NHLBI/WHO GOLD workshop summary).
