Abstract

A method for surgically treating tissue in a patient. The steps comprise touching a surgical tool to tissue that is to be surgically treated; heating the surgical tool by converging current to the tip of the surgical tool to create a high current density at the tip of the surgical tool so as to instantaneously vaporize the tissue being touched; and restricting the heat to the contact point on the tissue. The method eliminates the need for a solenoid coil and a grounding component.
