A Revolutionary Treatment For Adults Suffering From Severe Asthma

Safe, Effective, Proven


Bronchial Thermoplasty

Bronchial Thermoplasty (BT) delivered by the AlairTM System is a safe, effective, proven medical device procedure used as a treatment option for adults suffering from severe asthma. Clinical studies have proven that the BT procedure can reduce asthma attacks and emergency rooms visits for at least five (5) years in adult patients with severe asthma, and is shown to improve asthma‐related quality of life for people living with the disease. In fact, 79 percent of patients treated with BT saw a significant improvement in their asthma‐related quality of life1.

BT reduces asthma attacks by reducing airway smooth muscle. With less smooth muscle the airways constrict less, reducing asthma attacks and making breathing easier. Fewer asthma attacks means less need for the associated oral steroid treatment and its side effects.

The procedure is typically performed in an outpatient setting, and requires three visits to complete the process. Dr. William Smits is highly trained in treating severe asthma using the BT Alair System.

As with any procedure, there are risks, and individual results may vary. The most common side effect of BT is temporary worsening of respiratory‐related symptoms. This side effect typically occurs within a day of the procedure and resolves within 7 days on average with standard care. There is a small (3.4% per procedure) risk of these symptoms requiring hospitalization.2

    ... is why I decided to become a doctor. It troubles me to hear a patient describe how much they miss running, golfing, skiing and the like. Allergies and asthma no longer have to interrupt a person's life. That's why I teach medicine to the doctor's of tomorrow. To be able to give something back is very rewarding."
