Lung volume reduction with endobronchial coils



A : Coil, B: coil within the catheter, C : coil deployed once the catheter has been retrieved, D : Chest X ray before treatment, E : Chest X ray 3 months after right upper lobe treatment, F : Chest X ray 6 months after bilateral treatment(uppe lobes).
