Title: Randomized Controlled Trial Of RePneu (LVRC) Endobronchial Coils For The Treatment Of Severe Emphysema With Hyperinflation (RESET Study)
Brief Summary: The objective of this study is to demonstrate the safety and performance of the PneumRx, Inc. Lung Volume Reduction Coil (LVRC) in a population of patients with emphysema. The PneumRx, Inc. LVRC is used as a less invasive alternative to lung volume reduction surgery.
