This is an open label, single arm study to evaluate the safety and effectiveness of the AeriSeal System to block collateral ventilation (CV). Subjects will undergo instillation of AeriSeal Foam in the target lobe and subsequent assessment of CV status using Chartis Pulmonary Assessment System. Subjects with CV- status will then undergo placement of Zephyr Valves in the target lobe for bronchoscopic lung volume reduction (BLVR) and be followed for 24 months.
