  • Patent number: 6083250
    Abstract: An apparatus and method for preventing the formation of a herpes lesion by applying an electrical stimulation to the prodromal herpes lesion. The electrical stimulation apparatus is configured to be small enough to be hand portable and, preferably, concealable within the hand to accommodate treating the prodromal lesion at the onset of the formation of the prodromal lesion at any time and under any circumstance. The electrical stimulation is applied as an alternating current having a frequency range between one and 600 Hz. The alternating current is supplied with one of a square wave, a modified biphasic square wave, or a sine wave and between one and 100 milliamperes for a period of time up to 20 seconds.

  • Patent number: 5607461
    Abstract: An electrical stimulation apparatus and method for applying an electrical stimulation to a lesion. The apparatus includes a housing having a battery and an electrical circuit mounted inside the housing. A pair of electrodes are removably mounted to the housing and extend therefrom so as to accommodate being touched to the skin on opposite sides of the lesion. A switch on the housing allows the user to selectively supply electrical energy to the electrodes. A first light on the housing is illuminated when the switch is depressed thereby providing a visual indication that electrical energy is being supplied to the electrodes. A second light on the housing provides a visual indication of a low battery condition. A closure is mountable to the housing and encloses the electrodes, switch, and light within the closure.

  • Patent number: 5133352
    Abstract: The present invention provides an apparatus and method for treating infectious skin conditions, such as Herpes Simplex 1 and 2. By the application of an electrical field and current to the area of the manifestation of the disease on the body there is activated a reaction at the cell level to combat the virus and disrupt its attack on the healthy cell structure. The present method comprises a direct application of a low voltage direct current, low amperage stimulation to the skin about the infected location for a few seconds every hour for a length of time sufficient to prevent formation and/or heal the resultant lesion.
