Described embodiments include an apparatus that includes anintrabody probe and an electrode coupled to a distal end of theintrabody probe. The electrode includes a flexibleelectrically-insulating substrate, comprising a substrate surface. Theelectrode further includes a layer of an electrically-conductingmetal covering at least part of the substrate surface. Theelectrode further includes a metallic sheet, comprising an innersheet surface, and an outer sheet surface shaped to define multipledepressions. The electrode further includes an adhesive, whichfills the depressions and bonds the outer sheet surface to thelayer of the electrically-conducting metal. Other embodiments arealso described.
