1. A system comprising:

  • a wand comprising a non-conductive outer surface, at least three electrodes disposed on a distal end of the wand, and at least three electrical leads extending from a proximal end of the wand, and electrically coupled, one each, to one of the at least three a controller comprising;

    a controller connector coupled to the at least three electrical leads;

    a voltage generator configured to generate voltage of varying amplitude, the voltage generator has an active terminal and a return terminal; and

    a control circuit coupled between the controller connector and the active and return terminals;

    the control circuit configured to selectively electrically couple both the active terminal and the return terminal to the at least three electrical leads, such that any of the at least three electrodes are electrically coupled in combination to the voltage generator as an active electrode and as a return electrode.
