Electrosurgical device and method of use

An electrosurgical device for ablating tissue, comprising:

• a probe having a handle coupled to an elongate shaft with a working end;
• an RF source operatively coupled to a controller;
• a source of a conductive fluid communicating with a jetting channel having a jetting outlet in an electrically insulative component of the working end;
• a pump mechanism operatively coupled to the controller configured to provide a conductive fluid flow at a flow rate from 5 ml/min to 25 ml/min in the jetting channel;
• a first polarity electrode exposed to the conductive fluid flow proximal to the jetting outlet;
• a second polarity electrode at the working end spaced apart from the jetting outlet;
• and
• wherein the RF source and controller are adapted to couple RF current to the conductive fluid flow in the jetting channel to generate a plasma at the jetting outlet.
