Abstract: An elongate relatively rigid and electrically insulated vehicle is disclosed for use in fitting a vaginal or anal electrical stimulator used in treatment of urinary incontinence or sexual disfunction. The vehicle has spaced electrodes along its length which may be selectively actuated by a control unit to apply a pulsing voltage to the pelvic floor muscles. Pressure transducers located adjacent the electrodes measure the pressure applied by the muscles on the canal wall and a scale on the proximal end of the vehicle is used to determine the proper positioning of the electrodes and length of the vehicle for use in fashioning and fitting the patient with a proper electrical stimulator. A method for fitting the patient with such a stimulator using the vehicle is also disclosed.
