    Abstract: Systems and methods for enhancing surgical outcomes by providing generators having optimal RF output for sealing, fusing and/or cutting tissue or vessels under all dynamic conditions are described. Examples of dynamic conditions may include varying tissue impedance load due to electrosurgical operations or tissue affects, any operational conditions and commands determined by the surgeon, surgical procedure and/or device script. This is achieved by implementing a digital closed-loop control system within the electrosurgical generator to regulate voltage, current, and power of the RF output. The digital closed-loop control system may include an RF amplifier for generating RF energy, a feedback system for constantly monitoring the electrical characteristics, e.g., voltage, current, and power, of the supplied RF energy to a connectable electrosurgical instrument and a microcontroller for processing measurement data from the feedback system and adjusting the output of the RF amplifier to meet a desired regulation target under any varying conditions.

    Abstract: Systems and methods for performing impedance matching to enhance surgical outcomes in an electrosurgical system are described. An impedance matching network is interposed along a path of RF energy and matches dynamically an output impedance of an electrosurgical generator to an input impedance of the tissue load by varying the inductance of a resonant cell. As a result, an adjustment is made to the output phase of the electrosurgical generator to ensure an optimal matching of the source and load impedances based on sealing, fusing or cutting cycle of the tissue. This leads to a resonance condition which provides a zero-degrees phase shift between the RF output voltage and current of the electrosurgical generator. The inductance of the resonant cell is proportional to either the magnitude of the current flowing through DC windings of a saturable core reactor or on the size of an airgap in the inductor core material.

    Abstract: Systems and methods for performing a self-verification system test upon activation of an electrosurgical generator are described. The systems and methods allow for enhancing surgical outcomes by providing generators having accurate RF energy generation, measurement, calibration and self-testing system. This is achieved through implementation of an automated self-verification process at a power start-up of the generator, which allows for rapidly identifying a potential generator issue prior to any use of a connected electrosurgical instrument or supply of any RF energy to the tissue or vessel through the electrosurgical instrument. Additionally, one or more internal impedance loads are integrated within the electrosurgical generator. The internal impedance loads with multiple configurations are utilized to verify the voltage, current, power, and/or phase measurements of the generator. By incorporating or integrating the self-verification process and its related hardware resources within the electrosurgical generator, many improvements in outcome of pre-surgical procedures may be achieved.
