The patient is monitored after the procedure and usually returns home the day of the procedure or early the following day. The catheter delivers a series of 10-second temperature controlled bursts of

This reduces the capacity of the immune system to cause bronchoconstriction through nitric oxide signalling, which is the main root cause of asthma symptoms. Bronchial thermoplasty

In a clinical study, bronchial thermoplasty has been proven to provide long-term reduction in asthma induced breathing difficulty to at least 5 years and improve the quality of life for severe persistent asthma patients. Reduction in asthma attacks, ER visits, and hospitalizations for respiratory

In a double-blind, randomized, sham-controlled clinical study of bronchial thermoplasty, adults with severe asthma treated with bronchial thermoplasty had improved asthma-related quality of life out to a year compared to the control (sham-treated) patients. Additionally, when compared to control

Through a standard bronchoscopy procedure, a small flexible tube is advanced into the airway, via mouth or nose, to mildly heat the airway walls. This treatment has been shown to result in acute epithelial destruction with regeneration observed in the

A full course of bronchial thermoplasty treatment includes three separate bronchoscopic procedures: one for the each lower lobe of the lung and another for both upper lobes. Each outpatient procedure is performed approximately three weeks apart.

In the period immediately following the bronchial thermoplasty procedure, there was an expected transient increase in the frequency and worsening of respiratory-related symptoms. Bronchial thermoplasty is not appropriate for patients who:

Bronchial thermoplasty was first approved by FDA in April 2010. Bronchial thermoplasty is now being used as a treatment in many countries which include United
Kingdom, India, and United States.
