The dNerva® Lung Denervation System
The dNerva® Lung Denervation System consists of a console and the dNerva dual-cooled radiofrequency (RF) catheter. The console delivers the RF energy required to ablate the pulmonary nerves. The console includes a thermoelectric plate and pump that cools the fluid (dextrose 5% in water) circulating through the dNerva catheter to protect the airway wall during energy delivery, and a graphical user interface with a prompt screen to control the console and guide the user.
The dNerva dual-cooled catheter is a specialized, patented disposable component consisting of an umbilical that connects to the console, and a handle and shaft that are compatible with most flexible bronchoscopes utilizing a 3.2mm working channel. The distal balloon and electrode assembly have been designed to collapse to fit through the bronchoscope’s working channel.
