Patent ID: 7403807

Claim:
A medical electrode for conducting an electrical current to or from the skin of a patient, the electrode comprising: a flexible metallic conductor, the conductor having a peripheral edge, wherein the peripheral edge of the metallic conductor has at least some regions that have been worked more during manufacturing than other regions of the metallic conductor; a layer of electrolyte in electrical contact with the conductor and positioned to be in electrical contact with the skin when the electrode is applied to a patient, the layer of electrolyte having a peripheral area that overlaps the peripheral edge of the conductor, an insulating layer overlying the conductor, wherein a peripheral edge of the metallic conductor is sealed with an insulating material so that the regions that have been worked more are substantially out of electrical contact with the overlapping peripheral area of the layer of electrolyte, wherein the insulating material and the seal of the insulating material to the peripheral edge of the conductor is configured to reduce corrosion of the conductor at the regions of the peripheral edge that have been worked more.
