Airway Balloon Dilation

Airway Balloon Dilation

Airway stenosis is a congenital or acquired narrowing that obstructs the passage of air to the lungs. Symptoms include stridor, wheezing, hoarseness, shortness of breath and respiratory distress. Patients who have severe airway stenosis are often dependent on a tracheotomy tube to breathe.

The most common cause of acquired airway stenosis is endotracheal intubation, resulting in 90% of cases. Other causes include external trauma, thermal or caustic injuries, chronic inflammatory diseases, infection, and cancer.


The following diagram outlines the balloon dilation process:

The INSPIRA AIR® Balloon Dilation System is introduced into the airway under direct visualization. The airway stylet facilitates atraumatic access across narrow stenosis.

The balloon is gently inflated, applying controlled radial pressure to the stricture. After dilation, the balloon is deflated and withdrawn from the airway.
