1. A method for applying electrical energy to a target site on a structure on or within a patient'"'"'s body, the method comprising:

  • positioning an electrode terminal into at least close proximity with the target site in the presence of an electrically conducting fluid;

    positioning a return electrode within the electrically conducting fluid to generate a current flow path between the electrode terminal and the return electrode; and

    applying high frequency voltage to the electrode terminal and the return electrode such that an electrical current flows from the electrode terminal, through the target site, and to the return electrode through the current flow path.
