Asthma Soothed by Airway Radio-Blasts

A device that uses radio waves to heat the muscle lining of patients’ airways appears to treat their asthma. Just three sessions of the new treatment cut the number of mild asthma attacks in patients by a half during a one-year trial. The probe reduces inflammation in the bronchial tubes, doctors believe, and could lessen asthmatics’ need for steroids. The procedure, known as bronchial thermoplasty, involves inserting a long, thin catheter probe through the nose or mouth to reach the lung airways. Once the probe is in place, the tip is heated using radio waves. This raises the temperature in the muscle tissue of the airway up to 65°C for 10 seconds
