Alair Catheter: Sterile, single-use, disposable device delivers therapeutic RF energy to the airways via a standard flexible bronchoscope. Includes an electrode array with 4 insulated stainless steel wire legs; the 5-mm, exposed area at the center of the leg is the active electrode.

Alair Radiofrequency (RF) Controller: Designed with a proprietary set of control parameters and algorithms to safely and accurately deliver the correct intensity and duration of thermal energy. The energy delivery is designed to limit long-term impact to surrounding tissues.

Indications
In general, patients with airway remodeling and those with uncontrolled asthma, in spite of being treated intensely at step 5 or 6 by NAEPP guidelines, are most appropriate for this treatment option (1). Patient selection must exclude asthma mimetics such as ABPA, COPD, vocal cord dysfunction, Churg-Strauss syndrome, drug reactions, congestive heart failure, bronchiolitis obliterans, chronic sinus problems, severe GERD, excessive dynamic airway collapse, and tracheobronchomalacia.

Contraindications and Complications
The main complications of bronchial thermoplasty are asthma exacerbation, atelectasis, and hemoptysis.
