Airway Bypass - Safety and Feasibility Study

This study tests the safety and feasibility of a bronchoscopic procedure that creates tiny bypass channels in the lung airways to help air escape more easily in people with severe emphysema (a lung disease where air becomes trapped, making breathing very difficult). The procedure is done through a tube passed into the lungs — no surgery required. **You may be eligible if...** - You are between 50 and 80 years old - You have severe emphysema confirmed on a CT scan - You have significant breathing difficulty (breathlessness rated above 2 out of 4) - Your lung function tests show severe airflow obstruction and air trapping - You have stopped smoking for at least 8 weeks - You have completed pulmonary rehab in the past year or exercise regularly **You may NOT be eligible if...** - You have significant mucus production or frequent coughs - Your breathing can improve greatly with a bronchodilator (inhalers) - You have had recent lung infections or major health events - You are currently smoking Talk to your doctor to see if this trial is right for you.
