BT-Treated airway remains open during a simulated Asthma Attack

This demonstrates how Bronchial Thermoplasty reduced airway narrowing in response to direct application of methacholine (a bronchoconstrictor).

Bronchial Thermoplasty is an outpatient procedure performed by a BT-certified and experienced pulmonologist

BT is performed in 3 sessions

BT is complete after 3 sessions, each treating a different part of the lung to ensure safety (as Illustrated in the lung map). No incision is needed. BT is performed with a bronchoscope, inserted through the nose or mouth.

During the procedure, the Alairâ„¢ catheter delivers radiofrequency (RF) energy to the airway walls, applying mild heat in a controlled manner reducing the amount of excessive airway smooth muscle present in the airways.

It's important to note that no structural changes in the airways that were clinically significant were due to BT at 5 years.2
