Damaged Lung (IMAGE) University of Pennsylvania School of Medicine Caption This image shows the damaged lung tissue of an emphysema patient. Researchers at the University of Pennsylvania School of Medicine are now studying an investigational treatment that may offer a significant new, minimally-invasive option for those suffering from advanced widespread emphysema. The EASE (Exhale Airway Stents for Emphysema) trial focuses on a procedure called airway bypass that involves creating pathways in the lung for trapped air to escape -- and in turn, may relieve emphysema symptoms including shortness of breath.
