Patent ID: 8257349

Claim:
An electrosurgical generator having a closed loop control system comprising: a sensor system configured to sense at least one of a tissue property and an energy property at a tissue site, and to generate at least one sensor signal representative of the at least one of the tissue property and the energy property; a controller configured to select an electrosurgical operational mode from a plurality of electrosurgical operational modes in response to the at least one sensor signal; a radio frequency (RF) arbitrary source configured to generate an RF input signal representative of the selected electrosurgical operational mode; an RF output stage configured to generate a treatment signal corresponding to the selected electrosurgical operational mode; a high voltage power source configured to generate sufficient voltage for the operation of the RF output stage; and a predictive signal processor configured to alter operating characteristics of the high voltage power source and the RF output stage in response to the RF input signal, such that the RF output stage alters the treatment signal in real time based on the selected electrosurgical operational mode.
