LOS ANGELES, CA--(MARKET WIRE)--Jun 6, 2007 -- Researchers at Cedars-Sinai Medical Center announced today the start of the EASE (Exhale Airway Stents for Emphysema) Trial, an international, multi-center clinical trial to explore an investigational treatment that may offer a new, minimally-invasive option for those suffering with advanced widespread emphysema. The study focuses on an experimental procedure called airway bypass designed to create pathways in the lung for trapped air to escape with the goal of relieving shortness of breath and other emphysema symptoms.
