Inclusion criteria

  1. Obtained informed consent.
  2. Diagnosis of heterogeneous emphysema with a heterogeneity index of ≥10 % between target and adjacent lobes.
  3. Subjects of both genders of at least 40 years of age.
  4. 15 % predicted ≤ FEV1≤ 45% predicted.

Additional inclusion criterion French CIP*:

  • If treated in France, Subject must be entitled to French social security

Exclusion criteria

  1. Any contraindication for bronchoscopic procedure.
  2. Evidence of active pulmonary infection.
  3. History of 2 or more exacerbations requiring hospitalization over the past 12 months.
  4. Known pulmonary hypertension that according to the physician will be unsuitable for EBV treatment.
  5. Myocardial infarction or other relevant cardiovascular events in the past 6 months.
  6. Significant bronchiectasis seen at CT scan.
  7. Greater than two tablespoons of sputum production per day.
  8. Prior LVR or LVRS procedure. Criterion 8 French CIP wording*: Prior lung transplant, median sternotomy, LVR or LVRS procedure (including lobectomy).
  9. Pulmonary nodule requiring follow-up within any lobe.
  10. Pregnant or nursing women. French CIP wording*: Subject is pregnant or lactating, or plans to become pregnant within the study timeframe.
  11. Hypercapnia (paCO2 > 7.33 kPa).
  12. Current diagnosis of asthma.
  13. > 25mg Prednisolon (or equivalent) use/days.
  14. Any other condition that as judged by the investigator may make follow-up or investigations inappropriate.
  15. Evidence of pleural adhesions or earlier pulmonary surgery.
