an electrosurgery medical device is enhanced with unique solution - assistance , and comprises , in combination , co - operating device jaws including jaw portions for manipulating tissue , and a plurality of solution infusion openings defined and spaced along each of the jaw portions , for receiving electrolytic solution and infusing the solution onto and into tissue to be manipulated , along said jaw portions . as preferred , the device further comprises at least one , and most preferably , many , longitudinal groove along at least one and most preferably , both , of the jaw portions , with the solution infusion openings located in the groove or grooves . the solution is energized with rf energy and contributes to the functions and beneficial effects of the instrument . the solution exits the openings in the grooves at sufficient flow rates to separate substantially all the operative surfaces of the device from tissue , thereby substantially completely preventing adherence between the operative surfaces and tissue . the solution is further energized to a range of energy densities such that tissues to be affected are sealed against flow of blood , lymphatic fluids , air , and other bodily fluids and gases .
