Abstract
System and methods of an electrosurgical controller having multiple modes of operation that are configured for treatment of a specific targeted tissue type and the electrosurgical effect desired where the treatment and effect are provided by a single controller and an electrosurgical probe. The electrosurgical controller includes an integrated fluid control apparatus or pump where activation of the controller allows for selective energy delivery and corresponding fluid volume flow rates. The electrosurgical probe includes a fluid transport lumen and is in communication with the controller and the pump for operation of the probe in the various user selected modes with accompanying energy delivery and fluid control directed to the desired treatment and surgical effect.
