Abstract:
1. An electrosurgical generator configured to generate electrosurgical energy delivered to a patient for performing an electrosurgical procedure for sealing tissue, the generator comprising: at least one sensor configured to sense at least one of a physical and electrical property related to the delivery of the electrosurgical energy; at least one processor configured to receive sensed data corresponding to the at least one of the physical and electrical property and to process at least a portion of said received sensed data to control the electrosurgical generator, the at least one processor further configured to continuously compare the received sensed data to a mapping having a time-based plot of desired progression of the at least one of the physical and electrical property, the at least one processor configured to generate at least one control signal as a function of the comparison of the sensed data with the mapping for regulating electrosurgical energy output from said electrosurgical generator; and the at least one processor including a first control module for controlling an inner control loop for controlling the electrosurgical generator in accordance with a first mapping of the mapping and a second control module for controlling an outer control loop for controlling the second control module in accordance with a second mapping of the mapping.
