Bronchial thermoplasty is a non-drug procedure for severe persistent asthma in patients 18 years and older whose asthma is not well-controlled with inhaled corticosteroids and long-acting beta-agonists.

The system delivers thermal energy to the airway wall, in a precisely controlled manner, in order to reduce excessive airway smooth muscle. Reducing airway smooth muscle decreases the ability of the airways to constrict, and helps in reducing the number  of asthma attacks.

This minimally invasive bronchoscopic procedure is performed in outpatient procedure visits.

Bronchial thermoplasty is routinely performed under moderate sedation or light anesthesia, and the patient typically goes home the same day.

Bronchial thermoplasty is expected to complement asthma maintenance medications by providing long-lasting asthma control and improving asthma-related quality of life of patients with severe asthma. In addition, bronchial thermoplasty has been demonstrated to reduce severe exacerbations (asthma attacks) emergency rooms visits for respiratory symptoms, and time lost from work, school and other daily activities due to asthma.
