Interventional
Description of intervention(s) / exposure
Treatment: Devices - Exhale® Drug-Eluting Stent
Treatment: Devices - Sham control

Sham comparator: 2 - subject receives optimal medical management, supervised pulmonary rehabilitation therapy and undergoes bronchoscopy but no stents are placed

Experimental: 1 - subject receives optimal medical management, supervised pulmonary rehabilitation therapy and undergoes bronchoscopy during which up to six Exhale drug-eluting stents are placed in the lungs


Treatment: Devices: Exhale® Drug-Eluting Stent
Bronchoscopic procedure in which up to six Exhale Drug-Eluting Stents are placed in the lungs; total procedure time is 1 to 2 hours

Treatment: Devices: Sham control
5-10 minute bronchoscopic procedure in which the lungs are examined and a bronchial lavage is performed; the bronchoscope is then retracted to a point above the carina and below the vocal folds for the remained of the time; total procedure time is about 1-2 hours
