#### II. DEVICE DESCRIPTION

Mygen M-3004 RF System consists of a microprocessor based RF generator, a cooling pump and tubing, electrodes, and ground pads. The generator, pump and electrodes are designed to produce local tissue heating at the tip of the electrodes causing the coagulation (ablation) of the tissue. Mygen M-3004 RF System generator is capable of delivering up to 200 waits (into a 50 Ohm resistive load) while monitoring tissue impedance and electrode tip temperature during the RF energy. The generator includes manual and impedance control and displays/monitors impedance, current, power and temperature.

The radiofrequency (RF) energy, which is delivered to an electrode, makes frictional heat for coagulation and ablation on diseased tissue by ionic agitation. The patient can receive safe therapy as leakage current is extremely low. Mygen M-3004 continually measures and displays RF output power, tissue impedance, and elapsed time of RF delivery. Tissue temperature is measured by the thermocouple embedded in the electrode tip and is displayed on the touch screen. This equipment automatically adjusts the output to maximize the delivery of high-frequency energy and displays the measured temperature from the treatment site during high-frequency emission.

Mygen M-3004 automatically adjusts the output to optimize radiofrequency output and displays the measured temperature from the treatment area while delivering radiofrequency energy.
