Exclusion criteria

1. Prior lung volume reduction surgery, lobectomy or pneumonectomy, or lung transplantation

2. Requirement for ventilator support (other than CPAP or BPAP for sleep apnea)

3. Three (3) or more COPD exacerbations requiring hospitalization within 1 year of Screening visit or a COPD exacerbation requiring hospitalization within 8 weeks

4. Use of systemic steroids > 20 mg/day or equivalent immunosuppressive agents, heparins, oral anticoagulants or investigational medications

   Exclusion Criteria (continued):

6. CT scan: Presence of any of the following radiologic abnormalities:

   1. Pulmonary nodule on CT scan greater than 1.0 cm in diameter
   2. Radiologic picture consistent with active pulmonary infection
   3. Significant interstitial lung disease
   4. Significant pleural disease
   5. Giant bullous disease

7. Clinically significant asthma

8. Clinically significant bronchiectasis

9. Pulmonary hypertension

10. Allergy or sensitivity to medications required to safely perform AeriSeal System treatment under general anesthesia or conscious (moderate procedural) sedation

    2. Active malignancy
    3. Stroke or TIA within 12 months
    4. Myocardial infarction within 12 months
    5. Congestive heart failure within 12 months

16. Any condition that would interfere with the intent of the study or would make participation not in the best interest of the patient such as alcoholism, high risk for drug abuse or noncompliance in returning for follow-up visits
