CSA (Chronic Bronchitis) - Clinical Trial
What is the Purpose of this Study?
We are doing this study to find out what effects (good or bad) the study device (RejuvenAir) may have on people with chronic bronchitis.
This device uses a cryospray (liquid nitrogen) that will go directly into the airways for the treatment of chronic bronchitis.

-Be randomized (2 out of 3 will be in Group 1) to Group 1 or Group 2
---Group 1 will get the study cryospray during a bronchoscopy
---Group 2 will have a mock bronchoscopy that will not have the cryospray
Both groups will:
