Summary: | A surgical system and associated method for sealing the passageway of a fluid-carrying vessel comprises an electrosurgical generator capable of delivering electrosurgical power, a surgical instrument connected to the electrosurgical generator and adapted to transfer electrosurgical power from the electrosurgical generator to a pair of end effectors disposed at a distal end of the instrument. The system also includes a power control circuit for controlling the delivery of energy to the vessel through the end effectors, wherein the delivery of the radio frequency energy to the vessel comprises, raising the output current to a range below 1.75 Amperes RMS and the output voltage to a range below 135 Volts RMS. Radio frequency energy is applied to the vessel for a period of time while the power is held approximately constant. The flow of radio frequency energy is terminated when the impedance of the vessel being sealed reaches a predetermined level. |
