About Bronchial Thermoplasty Delivered by the Alair System

Bronchial thermoplasty is a novel non-drug treatment for asthma. The treatment is performed through the working channel of a standard flexible bronchoscope that is introduced through a patient’s nose or mouth, and into their lungs. The tip of the small diameter Alair Catheter is expanded to contact the walls of targeted airways. Controlled thermal energy is then delivered to the airway walls to reduce the amount of airway smooth muscle that narrows the airways in patients with asthma during an asthma attack. The minimally invasive procedure, like many other flexible endoscopy procedures, is done under light anesthesia and the patient returns home the same day. In the period immediately following bronchial thermoplasty, there is an expected increase and worsening of respiratory-related symptoms, which are of the type expected following bronchoscopy in patients with asthma. These typically occur within a day of the procedure and resolve on average within 7 days with standard care.

CAUTION: Alair System is an Investigational Device. It is limited by United States law to investigational use. To be used by Qualified Investigators only.
