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.

Condition or disease Intervention/treatment Phase
Chronic Bronchitis Device: RejuvenAir System Device: Sham Control Procedure Not Applicable

Detailed Description:
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.
