Engineered For Airway Management

Inspired by aerodynamics, the Spiration Valve redirects air away from diseased or damaged lung to healthier tissue, all while allowing trapped air and secretions to escape, so that patients may breathe easier. 

Unlike a stent, 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 Spiration Valve System is intended to treat severely diseased lung in patients with heterogeneous emphysema and evidence or markers of low collateral ventilation such as complete fissures, or damaged lung resulting in air leaks by limiting airflow to selected areas.

The procedure is considered minimally invasive and can be performed through a flexible bronchoscope.

On inhalation, the Spiration Valve conforms to the airway and redirects air to healthier tissues of the lung.


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.


Redirecting Airflow to Redirect Outcomes

Treatment with bronchial valves in patients with severe emphysema was developed to achieve lobar volume reduction without the risks of mortality and morbidity associated with surgical procedures. Studies suggest that an optimal treatment approach for bronchial valve treatment may involve complete occlusion of a single lobe, and careful selection of appropriate patients with complete fissures and high heterogeneity using HRCT and perfusion scan analysis.1,2,3  Learn more about selecting appropriate patients that may benefit from the Spiration Valve System.

Spiration Valve treatment benefits may include reduction in hyperinflation, improvements in pulmonary function as indicated by an improvement in FEV1, improved exercise tolerance, and improved quality of life as measured by SGRQ.1,2

Inspiration Meets Innovation

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.
