A transcutaneous electrode device permits an electrical signal to be transmitted to or received from an anatomical site of a human patient when that site is covered by an intervening plaster or synthetic cast. The device includes a flange assembly and a collar assembly (which cooperate to capture the cast and define an aperture through the cast) and an electrode tampon assembly (which is inserted through the aperture to provide electrical contact to the anatomical site). The electrode tampon assembly includes an external barrel or carrier which is insertable in the aperture, an electrically conductive medium (such as a sponge saturated with a conductive fluid) carried at the distal end of the barrel, and an electrical connector at the proximal end of the barrel. A coil spring urges the conductive medium into contact with the anatomical site and provides electrical connection between the conductive medium and the electrical connector.
