Brief Summary:
VAST is a multicenter, prospective, randomized, controlled study designed to evaluate treatment of persistent air leak with the SVS as compared to standard chest tube drainage management and other standard-of-care interventions in the control group. Eligible subjects will be randomized to receive either Spiration Valves (investigational arm) or continue standard-of-care treatment (control arm). Once the air leak has resolved, Spiration Valves should be removed.

Condition or disease Intervention/treatment Phase
Pulmonary Air Leaks Device: Spiration Valve System Not Applicable

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 200 participants
Allocation: Randomized
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Safety and Effectiveness of the Spiration Valve System (SVS) in Air Leaks
Study Start Date : May 2015
Estimated Primary Completion Date : December 2018
Estimated Study Completion Date : December 2018

Arm Intervention/treatment
Experimental: Spiration Valve System
The treatment group will have valves deployed to achieve leak isolation.
Device: Spiration Valve System
No Intervention: Medical Management
The control group for this study will receive standard chest tube drainage management and standard-of-care interventions. This group will be evaluated and followed in the same manner as the treatment group, but without having valves placed.

Primary Outcome Measures :
  1. Time to Air Leak Cessation [ Time Frame: Two weeks ]

Other Outcome Measures:
  1. Incidence of SAE [ Time Frame: Six weeks ]
