RheOx® System
The RheOx system has CE certification.
The RheOx system is an investigational device in the United States. Limited by Federal (or United States) law to investigational use.
The RheOx® system for the treatment of the symptoms of chronic bronchitis consists of a proprietary electrosurgical generator and a single-use catheter. The minimally-invasive bronchoscopic therapy delivers short bursts of non-thermal energy to the airways in the lung to reduce the abnormal mucus-producing cells, leaving the extracellular matrix intact so that the epithelium may rapidly regenerate.
