  • Patent number: 8239018
    Abstract: An electrode assembly for use in an iontophoresis device for the transcutaneous administration of an active therapeutic species has a base layer of including a linking conductive base material which is consumed (oxidizes or reduces) preferentially to water, a first upper layer of sacrificial material coated on a first portion of the base layer wherein the sacrificial material is consumed preferentially to the linking conductive base material of the base layer. A second upper layer of non-conducting material is coated on a second portion of the base layer, the second upper layer being spaced from the first upper layer, connected by a narrow exposed linking area of the base layer material remaining exposed therebetween.
