New technology means asthma patients may have a chance to breathe easier.
Thanks to a treatment called bronchial thermoplasty.
It works by delivering heat into sections of the lungs though a special catheter.
The heat stops these airways from tightening up during asthma attacks.
The end result is more air entering the lungs, which means fewer and less severe asthma attacks.
The procedure is completed in three separate sessions, each targeting different area of the lungs. The sessions are scheduled three weeks apart to allow recovery time.
