Abstract
A vibratory method for treating female voiding dysfunctions by applying to the inner walls of the urethra radial expansion forces combined with axial friction forces. This improves blood circulation, trains the urethral sphincters, and produces massaging action on the urethral walls. A device for realization of the method comprises a probe (12) formed of two rods (16) and (18) and a drive unit (14). Drive unit (14) have two output elements, which reciprocate simultaneously in mutually opposite directions. Each rod (16, 18) is connected to a respective drive unit. On their inner or mating surfaces the rods have respective cams (32, 34) and curved grooves (36, 38). During reciprocation of the rods, the cams and grooves interact and thus provide radial expansions of probe (12). Massaging action is provided by serrations (40) which are formed on the outer surface of the rods and massage the inner walls of the urethra through application of friction forces. The rods can be made from plastic and used as a sterilized disposable unit.
