  Outcome Measures
  Show All Outcome Measures

1.  Primary:   The Effectiveness Endpoint is an Improvement in Luminal Patency Following Cryospray Treatment Along With Visual Confirmation of an Absence of Scarring and Stricturing of the Airway. Primary Safety Endpoint is the Reporting of All Adverse Events.   [ Time Frame: 24 months ]

2.  Secondary:   A Measure of Treatment Durability. If After the Initial Repeat Bronchoscopy, the Investigator Determines That There is no Immediate Need for Further Intervention, Then Any Future Bronchoscopy Will be Performed Upon the Patient Presenting With Symptoms.   [ Time Frame: 24 months ]
