• 1. Currently participating in another clinical study that involves surgery, interventional or pharmaceutical treatment; α-1 Antitrypsin deficiency 3. Women of child-bearing potential. 4. More than 2 COPD exacerbation episodes requiring hospitalization in the last year prior to screening; Any COPD exacerbations requiring hospitalization within 6-weeks of planned intervention; Two or more instances of pneumonia episodes requiring hospitalization in the last year prior to screening; Clinically significant mucus production or chronic bronchitis. 8. Myocardial Infarction or unstable / uncontrolled congestive heart failure within 6-months of screening; Prior lung transplant, LVRS, bullectomy, lobectomy or endoscopic lung volume reduction (ELVR); Clinically significant bronchiectasis. 11. Unable to safely discontinue anti-coagulants or platelet activity inhibitors for 7-days; Uncontrolled pulmonary hypertension (systolic pulmonary arterial pressure >45 mm Hg) or evidence or history of cor pulmonale as determined by recent echocardiogram (completed within the last 3-months prior to screening visit). Note: the echocardiogram is not a required screening procedure; Suspected malignant pulmonary nodule or other lung cancer. 14. HRCT collected per CT scanning protocol within the last 6-months of screening date and evaluated by clinical site personnel using 3D segmentation software shows:; Large bullae encompassing greater than 30% of either lung; Insufficient landmarks to evaluate the CT study using the software as it is intended; All lobes are less than 25% parenchyma diseased (< -950 HU) 15. Any cardiac comorbidity which the PI believes would compromise the safety of the patient after an IAB implant; TLC < 100% predicted at screening. 17. DLCO < 15% or > 50% of predicted value at screening. 18. PaCO2 > 50 mm Hg at screening. 19. PaO2 < 45 mm Hg in room air at screening. 20. Plasma cotinine level > 13.7 ng/ml or carboxyhemoglobin (arterial or ear lobe capillary) >2.5% at screening; Current diagnosis of substance abuse disorder. 22. Current diagnosis of any of the following: Major Depressive Disorder (MDD), Schizoaffective Disorder, Schizophrenia, Borderline Personality Disorder, Bipolar Disorder; Any other conditions, which, in the opinion of the Investigator, would make the patient unsuitable for inclusion, or could interfere with the patient participating in or completing the study
