About Bronchial Thermoplasty
Bronchial thermoplasty is an innovative, new, non-drug procedure developed for the treatment of severe persistent asthma. Bronchial thermoplasty delivered by the Alair® System uses thermal energy to reduce the muscle associated with airway constriction in asthma patients. Clinical studies of this treatment have demonstrated sustained improvements in asthma control up to a year following the treatment. Treated patients not only enjoyed improved asthma-related quality of life for the year following treatment but also fewer severe asthma attacks, fewer visits to the emergency room for respiratory symptoms, and fewer days lost from work/school or other daily activities due to asthma symptoms.
Overview of Bronchial Thermoplasty Procedure
Bronchial thermoplasty delivered by the Alair® System is performed under direct visualization 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 reachable by the bronchoscope. Controlled thermal energy then is delivered to the airway walls to reduce the presence of airway smooth muscle that narrows the airways in patients with asthma.
Bronchial thermoplasty is performed in a bronchoscopy/ endoscopy suite and takes about an hour to complete. The minimally invasive procedure, like many other flexible endoscopy procedures, is done under moderate sedation. No
incision is necessary. Post-procedure, patients typically are observed and monitored for approximately 2-4 hours.
There is an expected transient increase in the frequency and worsening of respiratory-related symptoms immediately following bronchial thermoplasty. These events typically occur within one day of the procedure and resolve within seven days, on average, with standard care. An overnight hospital stay may be appropriate in the event of worsening asthma symptoms after the procedure.
