ABSTRACT:
A conductive medical electrode formed from a moldable, conductive material such as carbon-filled plastic. In one embodiment, the electrode is an integral, conductive electrode including a stud adapted to detachably couple the electrode to a lead wire and a body integral with the stud. The body has a face disposed opposite the stud, for contacting a patient, which has a grooved pattern formed therein. The grooved pattern increases the surface area of the electrode in contact with a conductive adhesive and increases the conductivity between the patient and the electrode. A second embodiment features a two-piece, conductive electrode including an electrically conductive stud and an electrically conductive substrate having an opening formed therein and attached to the stud. The opening formed in the body creates a cavity which aids in retaining the conductive adhesive. The substrate has a face disposed opposite the stud, adapted to contact a patient, which has a grooved pattern formed therein. In a third embodiment, the conductive electrode includes a lead wire which is ultrasonically welded to the electrode body. Also provided is a method of manufacturing the integral, conductive electrode.
