Over 3 million people in the United States and tens of millions more throughout the world live with emphysema, a chronic, progressive, irreversible disease of the lungs.

New treatment options may help individuals with emphysema maintain a better quality of life by reducing the amount of air trapped in their lungs and making it easier for them to breathe.

This website provides information about a clinical research trial that will evaluate a novel investigational medical procedure called airway bypass for safety and effectiveness in the treatment of advanced widespread ("homogeneous") emphysema. It is called the EASE Trial, which stands for Exhale Airway Stents for Emphysema.
