Abstract
A surgical system and method for fusing tissue are disclosed. The system has an electrosurgical generator capable of delivering electrosurgical power, a surgical instrument electrically connected to the electrosurgical generator and adapted to transfer the electrosurgical power from the electrosurgical generator to a distal end of the surgical instrument, and a power control circuit for controlling the delivery of radio frequency energy to the tissue in contact with the distal end of the surgical instrument. The surgical system is configured to: deliver the radio frequency energy at a non-pulsing power to the tissue for a period of time of 3 seconds or less, wherein the non-pulsing power is held constant, the output current is held under 2 Amperes RMS, and the output voltage is held under 100 Volts RMS, the non-pulsing power further causing the tissue to begin to desiccate and to fuse within the period of time.
