COBLATOR® II (RF80000E) SYSTEM 9 User’s Manual
The Coblator II (RF8000E) System Controller is designed to deliver RF energy to the electrode elements located at the distal end of the sterile single-use Wands. Current flows between the active electrode element and the return electrode element, providing a localized energy field. The result of this arrangement is controlled energy delivery with minimal collateral tissue damage. The Coblator II (RF8000E) System works by passing RF energy through a conductive solution (such as normal saline) in close proximity to or in contact with the tissue to be treated. The conductive solution forms a thin layer between the active and return electrode elements. In the Coblate mode, when sufficient energy is applied, the conductive solution is converted into a vapor layer (plasma) containing energized charged particles. When the highenergy charged particles come in contact with tissue, they cause its disintegration through molecular dissociation. This mode of operation results in relatively low treatment site temperatures when compared to conventional electrosurgical systems, thus yielding limited collateral thermal damage to the surrounding untreated tissue. The function of the device is different when a lower voltage is applied between the active electrode(s) and the target tissue. In this case, the electrical field is below the threshold required to create a plasma layer and resistive tissue heating occurs. This mode is useful when a greater thermal effect is needed, i.e. for coagulation of blood vessel or other vascular tissues. The appropriate voltage setting will depend on the design of Wand used, tissue type, and desired tissue effect. In contrast, monopolar systems only have an active electrode on the device tip. The current path travels from the active electrode through the patient’s body to a return pad affixed to the patient’s body. This results in significantly more energy passing through the patient’s body and through the surrounding tissue.
