Gala Therapeutics’ RheOx system has received the CE Mark for treating patients with chronic bronchitis, a type of chronic obstructive pulmonary disease (COPD) in which the inflamed bronchial tubes create excessive mucus.

The device is used in a minimally invasive procedure called Bronchial Rheoplasty, in which it gives off non-thermal energy to the airways to reduce mucus-producing cells.

The company said it now plans to begin a postmarket study at key European respiratory centers to increase clinician experience with the procedure and device.
