  • Patent number: 8041430
    Abstract: A TENS currents application device has a composite laminated construction consisting of an electrical current conductive layer made of a carbon material sandwiched between a flexible outer layer and a body contact layer. The outer layer may be made of plastic or metal and has a plurality of magnet elements imbedded therein. A heating means may be additionally provided in the device. The device may be in the form of a disc or round ball which can be held in the palm of a patient or in the form of a sole insert which can be placed in the sole of a foot ware. Protruding points are additionally formed on the outer surface of the round ball and on the outer surface of the sole insert. A vibrating device is located in the handheld device for providing additional massaging function to enhance the TENS treatment.
