1. An electrosurgical generator for fusing or sealing tissue comprising:
a controller configured to:
instruct an RF amplifier to apply a first pre-determined amount of RF energy to an area of tissue,
determine a desiccation level of the area of tissue affected by the applying of the first pre-determined amount of RF energy,
instruct the RF amplifier to reduce the first pre-determined amount of RF energy being applied to the area of tissue to a second amount of RF energy based on the determined desiccation level,
instruct the RF amplifier to increase an amount of RF energy being applied to the area of tissue from the second amount to a third amount, wherein a rate of ramping the increasing amount of RF energy being applied and the third amount of RF energy to be applied to the area of tissue are based on the determined desiccation level, and wherein the third amount is between the first amount of RF energy and the second amount of RF energy,
instruct the RF amplifier to maintain the third amount of RF energy being applied to the area of tissue, and
instruct the RF amplifier to terminate the application of the RF energy to the area of the tissue after a first pre-determined period of time has elapsed; and
an RF amplifier configured to generate a corresponding amount of RF energy that is passed to an electrosurgical instrument connected to the electrosurgical generator, wherein the corresponding amount of RF energy generated is based on the instructions provided by the controller.
