Thermal energy treats asthma

In use, the company’s Alair Bronchial Thermoplasty System delivers thermal energy to the airway wall in a precisely controlled manner to reduce excessive airway smooth muscle.

Airway smooth muscle is located within the walls of airways in the lung and the excessive and inappropriate constriction of the muscle is a predominant feature of asthma. Reducing airway smooth muscle decreases the ability of the airways to constrict, thereby reducing the frequency of asthma attacks.

The bronchial thermoplasty treatment is performed using a flexible bronchoscope that is introduced through a patient’s nose or mouth, and into their lungs. The tip of a small-diameter catheter is then expanded to contact the walls of targeted airways. Controlled thermal energy is then delivered to the airway walls to reduce the presence of the excess airway smooth muscle.

The minimally invasive procedure, like many other flexible endoscopy procedures, is done under moderate sedation and the patient typically returns home the same day.
