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.


Redirecting Air Flow

Persistent air leaks continue to be a leading cause of increased hospitalization, morbidity and cost. Traditional management of persistent leaks involves chest drainage and observation followed by more invasive treatments when leaks do not resolve.1, 2, 3

Traditional “wait and see” approaches can lead to increased length of stay (LOS) and frustration for both the provider and patient.1, 2 The Spiration Valve System is minimally invasive procedure that provides surgeons and pulmonologists a predictable method for limiting distal airflow to diseased lung. It is a proactive option in the management of persistent air leaks.4, 5

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.


Inspiration Meets Innovation

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. Once in place, the Spiration Valve limits airflow to damaged tissue while allowing trapped air and fluid to escape. A reduction in air flow to damaged lung has been shown to accelerate resolution of an air leak. Because air leaks are transient in nature, the Spiration Valve was designed to be removed upon resolution of the leak.4
