For the Treatment of Prolonged Air Leaks

Postoperative air leaks continue to be the most common complication following surgical resection of the lung. Traditional management of prolonged air leaks involves chest drainage and observation followed by more invasive treatments when leaks do not resolve.1,2 This traditional “wait and see” approach can be associated with significant morbidity, increased mortality, prolonged hospital stay and increased use of healthcare resources.2 
An air leak present by day 5 should be considered for thoracic surgical consultation or treatment.1

A minimally invasive solution for prolonged air leaks

The Spiration Valve is an umbrella-shaped, one-way valve that is placed via a delivery catheter introduced through the working channel of a flexible bronchoscope. The valve consists of a nitinol frame covered with a polymer membrane and five anchors that securely engage the airway walls at the targeted treatment location. The unique design of the Spiration Valve minimizes contact with the bronchial wall, maintains position to redirect air even in complex patients, and facilitates removal when needed. 

The right patient. The right product. The right outcomes.

This treatment approach and algorithm based on quantitative air leak monitoring may lead to safe and successful air leak cessation at a median of 2 days after valve therapy and chest tube removal at a median of 4 days after valve therapy in the hands of trained physicians.1

Valve treatment for prolonged air leaks is an easily reversible procedure.2

Interventions to reduce prolonged air leak may not only benefit patients by decreasing complications and hospital length-of-stay but also save health care resources with the potential to significantly preserve hospital margin.1,2



On inhalation, the Spiration Valve may stop or reduce the amount of air flowing to portions of lung with an air leak.

On exhalation, the Spiration Valve flexibly constricts with the airways, allowing trapped air and secretions to escape naturally along the bronchial wall between the umbrella struts.

The Precision You Need for the Outcomes You Want

  • Persistent air leaks impact inpatient and outpatient resources utilization, cost, and morbidity.2 
  • A substantial reduction in an air leak using Spiration Valves may accelerate the resolution of an air leak. Complete cessation of an air leak may not be achievable, or necessary, for successful treatment.1



Stays in Place
The first and only valve with anchors
