VVR Generator System consists of Generator (VVR Generator), Active electrode (VENISTAR) and accessory such as foot switch and cooling pump. The generator generates, controls and monitors RF energy and delivers energy to the active electrode. The active electrode has an active coil and a receiver coil that allow the RF energy to flow through the tissue. The RF energy raises the temperature in the tissue, causing coagulation and occlusion of blood vessels. The single footswitch works as an on/off switch and the double footswitch works to increase or decrease the power output. A cooling pump circulates water around the electrodes to reduce the temperature of the electrodes and prevent tissue sticking to the electrodes.
An electrically-powered, noninvasive device designed to generate radio-frequency (RF) electrical current used to create heat via a percutaneously (through the skin) introduced electrode(s) in a precise location, at a controlled temperature, for focal ablation of non-cardiac tissues (e.g., non-cardiac nerves, tumours, precancerous tissue); it may be intended for coagulation however it is not intended for electrosurgical cutting. The generator connects via a delivery cable to an electrosurgical ablation probe/catheter (not included) to transmit the RF electrical current to the operative site; it might additionally be intended to heat an electrode tip (electrocautery).
