An electrode apparatus includes a handle, a housing extending from the handle, and a plurality of wheels partially contained within the housing. A plurality of needles extend from a perimeter of each of the wheels for penetrating an epidermis of skin and into the dermis and the subcutaneous layer of skin. A contact ring is disposed adjacent the plurality of wheels and a pin interconnects the contact ring and at least one of the wheels. The plurality of wheels and the contact ring rotate in unison about a central axis. A contactor remains in continuous contact with the contact ring as the contact ring and the plurality of wheels rotate about the central axis. Electrical current, in the form of bipolar or monopolar power, is transmitted through the needles via the contactor, the contact ring, the pin, and the wheels to treat layers of the skin. |
