Brief Summary:
Chronic Obstructive Pulmonary Disease (COPD) is defined as an impaired ability to move air within the lungs and is a major public health problem that is projected to rank fifth worldwide in terms of disease burden and third in terms of mortality. Chronic bronchitis (CB) is a common clinical phenotype within the umbrella of a COPD diagnosis and is classically defined as chronic cough and sputum production for 3 months a year for 2 consecutive years2, but many studies have used different definitions to define it- chronic cough and sputum production for one year or cough and sputum production on most days of the week. CB is associated with multiple clinical consequences, including; the worsening of lung function decline, increasing risk of acute exacerbations of COPD, increased risk of developing pneumonia, reduced health related quality of life, and an increase in all-cause mortality.

| Chronic Bronchitis | Device: RejuvenAir System Device: Sham Control Procedure | Not Applicable |
The RejuvenAir® System is a cryosurgical device that applies medical-grade liquid nitrogen to the treatment area via a radial head catheter in a small, accurately directed spray. Cryotherapy with the RejuvenAir® System is designed to induce a regenerative endobronchial tissue effect by: 1) destroying via cryotherapy the abnormal surface epithelium that has become overgrown with mucin producing goblet cells, 2) thus allowing normal bronchial epithelium with a regrowth of ciliated epithelial cells that will facilitate the removal of mucins from the bronchial airways and 3) lead to a reduction in chronic inflammation and its accompanying mucosal swelling with resultant increase in the treated airway diameter. This reversal of inflamed epithelium may also lessen systemic inflammation.

Subject agrees to continue maintenance pulmonary/COPD medications (GOLD standard medications recommended) for the duration of the study
- Smoking history of at least 10 pack years
- Non-smoking for a minimum of 2 months prior to consent and agrees to continue not smoking for the duration of the study
- Subject is able to adhere to and undergo 2 bronchoscopic procedures (cross over subjects may undergo two additional bronchoscopic procedures, if they agree to treatment), per hospital guidelines
- Subject demonstrates ability and willingness to use a daily eDiary
Exclusion Criteria
- Subject has had an acute pulmonary infection, exacerbation or pneumonia requiring medical treatment (with antibiotics and/or steroids) within 4 weeks prior of initially planned study bronchoscopy
