This study is looking at the long-term safety and effectiveness of the Spiration Valve System (SVS) for adults with severe emphysema. Emphysema is a lung condition that causes shortness of breath. The Spiration Valve System uses one-way valves placed in the lungs to help improve breathing. To join, you must be an adult with severe emphysema and have low collateral ventilation (a specific lung characteristic). The study will track how often certain chest-related side effects occur over 12 and 36 months after the valves are implanted. This study is currently unclear on its recruitment status.
