sphincter in a step 304 a syringe is connected to the female coupling 132 133 or 134 in a step 305 the syringe is used to exert positive pressure and inflate the balloon 123 with air or with a liquid inflation of the balloon 123 serves several purposes in addition to positioning the electrode 122 the balloon 123 also helps anchor the catheter 110 and prevents gas liquid or fecal matter from contaminating the region if necessary a second balloon can be used to anchor the catheter distally in a step 306 inflation of the balloon 123 causes expansion of the set of struts 121 any corrections in the positioning of the catheter 110 are made at this time using the visual apparatus coupled through the port 131 in a step 307 four or more electrodes 122 are selected for extension into the involuntary sphincter the mechanical switch 135 is used to extent the electrodes 122 into the involuntary sphincter thermal injury to sensitive female structures is avoided by selecting electrodes 122 in area other than the anterior portion of the anus in both sexes treatment is directed to the area one to two centimeter above and up to one centimeter.
