Inclusion Criteria: 1. Age ≥ 35 and ≤ 80 years old 2. Computed tomography (CT) scan evidence of homogeneous or heterogeneous emphysema 3. At least one target lobe with \> 35% destruction (percent of voxels with \< -950 Hounsfield units on CT) 4. Post-bronchodilator ratio of FEV1/FVC \< 0.7 at screening 5. Post-bronchodilator FEV1 percent predicted ≥15% and ≤50% of predicted at screening 6. Post-bronchodilator RV \> 180% predicted 7. Post-bronchodilator RV/TLC ≥ 0.55 at screening 8. Marked dyspnea, scoring ≥ 2 on the modified Medical Research Council scale of 0-4 9. Cotinine testing or carboxyhemoglobin at screening indicates nonsmoker and stopped smoking at least 8 weeks before entering the trial and agrees to refrain from smoking for duration of study participation 10. Participation in a pulmonary rehabilitation program and/or confirmed to have been engaged or attempted regular physical activity in the 12 months prior to the first Apreo Procedure and agrees to continue or restart regular physical activity for the duration of the study 11. Fully vaccinated for Covid-19 (up to date per local government guidelines) and has current pneumococcus and influenza vaccination (or documented clinical intolerance) 12. Cognitively and physically able to provide written informed consent and complete participant questionnaires Exclusion Criteria: 1. Arterial blood on room air: PaCO2 \> 50 mmHg (8 kPa) or PaO2 ≤ 45 mmHg (6 kPa) 2. DLCO \<20% at screening 3. Steroid therapy of 10 mg prednisolone (prednisone) or more per day 4. Two or more hospitalizations for acute exacerbations of COPD or respiratory infections in the past year before enrollment 5. Any acute exacerbation of COPD or respiratory infection less than 4 weeks before the first Apreo Procedure 6. Previous lung volume reduction surgery or lobectomy, segmentectomy or bullectomy, vapor, glue, or other pulmonary device implant 7. Known or suspected history of pulmonary arterial hypertension with a PASP \> 50 mmHg on echocardiogram or mPAP \> 25 mmHg on a right heart catheterization 8. Presence of a giant bulla (≥ 30% of hemithorax) 9. History of adult asthma or chronic bronchitis 10. Presence of suspicious pulmonary nodule/infiltrate that requires additional follow-up, diagnostics or treatment 11. Unequivocal and symptomatic bronchiectasis 12. Unequivocal lung cancer or other current cancer diagnosis except non-metastasized basal cell skin cancer 13. Uncontrolled hypertension (blood pressure that is inadequately treated or resistant to treatment) with a systolic \> 200 mmHg or diastolic \> 110 mmHg at screening or prior to first Apreo Procedure 14. Uncorrectable coagulopathy or other condition likely to increase risk of peri- or post- Apreo Procedure bleeding 15. On anticoagulant or antiplatelet therapy and unable or unwilling to hold for Apreo Procedure 16. History of myocardial infarction or unstable angina within past 6 months 17. History of a stroke less than 1 year before the first Apreo Procedure 18. Clinical history of heart failure with documented LVEF ≤ 40% 19. Clinical history of diabetes with a HbA1c \> 9.0% 20. Estimated glomerular filtration rate (eGFR) \<30 mL/min/1.73m2 (CKD-EPI) OR participant with kidney failure (Stage 5 kidney disease) 21. Mechanical ventilator dependence except participants using nocturnal bi-level positive airway pressure (biPAP) or continuous positive airway pressure (CPAP) are allowed if it would not preclude safe implantation of the study device 22. Pregnant, lactating, or women of childbearing potential who plan to become pregnant within the study duration 23. Known hypersensitivity to nitinol 24. Significantly immunocompromised, such as organ transplant recipients, those with congenital immune deficiencies, AIDS, or severe rheumatoid arthritis 25. Any disease or condition likely to limit survival to less than one year 26. Concomitant illnesses or medications that may pose a significant increased risk for complications following an Apreo Procedure 27. Currently enrolled in another trial and actively receiving experimental treatment 28. Any condition in the opinion of the investigator that would interfere with safe and complete collection of study data including the safe conduction of bronchoscopy procedures
