A percutaneous intradermal electrical connection system and implant device, the implant device including a flange and a neck extending from the flange. The neck has a cavity in its end and is provided with a lip for inhibiting the growth of epithelial or connective tissue over the neck cavity. A connecting device is partially housed within the neck cavity and allows a lead connected to the implant device to rotate through 360.degree.. The entire surface of the implant device may be electrically conductive and connected to the lead or, alternatively, the implant device may be provided with a separate electrode portion with the remainder of its surface being electrically insulated from the lead. In a preferred embodiment, the implant device is a unitary titanium member whose surface may be partially anodized to provide an insulated surface and establish the separate electrode portion. A preferred connecting device embodiment is magnetic.
