1. An electrosurgical system comprising:
an electrosurgical instrument; and
an electrosurgical generator removably coupled to the electrosurgical instrument, the electrosurgical generator configured to:
supply RF energy having an initial voltage spike to the electrosurgical instrument, wherein the initial voltage spike has a voltage increasing between a first predetermined voltage level to a second predetermined voltage level,
change voltage of the supplied RF energy from the second predetermined voltage level to a third predetermined voltage level with a following voltage ramp up to a fourth predetermined voltage level, wherein the third predetermined voltage level is less than the second predetermined voltage level,
monitor current of the supplied RF energy during the following voltage ramp,
terminate the following ramp up and hold the voltage of the supplied RF energy at a post-ramp voltage level when the monitored current drops below a pre-determined current threshold, and
end the supply of the RF energy to the electrosurgical instrument after holding the voltage of the supplied RF energy at the post-ramp voltage level for a pre-determined period of time.
