Abstract
An implantable cardiac electrode includes a flexible polymeric substrate, a metallized surface layer of the polymeric substrate forming one or more electrically conductive regions on the surface of the polymeric substrate, and one or more insulated conductors connecting the electrically conductive regions to leads, the leads being connected to a cardiac monitoring and pulse generating system. In one embodiment, the electrically conductive region forms a band on the outer surface of a polymeric tube and is electrically connected to a conductor embedded in the tube. In another embodiment, the electrically conductive region forms a desired configuration on a planar surface of the polymeric substrate, such as a concentric ring or spiral patch configuration. In these and other embodiments, the metallized surface layer includes a surface layer of the polymeric substrate that is impregnated with a metal such that a conductive region is formed in the surface of the otherwise insulative polymeric substrate.
