Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Signed Informed Consent.
- Diagnosis of COPD/emphysema.
- At least 22-years of age.
- 18 ≤ BMI ≤ 32.
- 6-minute walk Distance between 100-meters and 400-meters at baseline exam.
- Stable disease with less than 10-mg prednisone (or equivalent) daily
- Non-smoking for 4-months prior to screening interview (including tobacco, vaping, marijuana, etc.).
- FEV1 between 15% and 50% of predicted value at baseline exam.
- FEV1/FVC \<70%.
- Subject has ≥25% emphysema destruction score in each lung defined by areas of low attenuation \<-950 HU, as determined by CT core lab.
- Subject has homogeneous or heterogeneous emphysema, and at least one lung has a 15% difference between upper and lower lobes in emphysema destruction score (\< -950HU) as determined by CT core lab.
- RV \> 175% of predicted value.
- mMRC score ≥ 2.
Exclusion criteria
- 1\. Currently participating in another clinical study that involves surgery, interventional or pharmaceutical treatment.. 2\. 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. 5\. Any COPD exacerbations requiring hospitalization within 6-weeks of planned intervention. 6\. Two or more instances of pneumonia episodes requiring hospitalization in the last year prior to screening. 7\. Clinically significant mucus production or chronic bronchitis. 8. Myocardial Infarction or unstable / uncontrolled congestive heart failure within 6-months of screening. 9\. Prior lung transplant, LVRS, bullectomy, lobectomy or endoscopic lung volume reduction (ELVR). 10\. Clinically significant bronchiectasis. 11. Unable to safely discontinue anti-coagulants or platelet activity inhibitors for 7-days. 12\. 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. 13\. 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. 16\. 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. 21\. 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. 23\. 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.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
