16. Apparatus, comprising:
(a) an intrabody probe; and
(b) an electrode coupled to a distal end of the intrabody probe, the electrode forming a cylindrical shape, the electrode comprising:
(i) a flexible electrically-insulating substrate, comprising a substrate surface,
(ii) a layer of an electrically-conducting metal covering at least part of the substrate surface,
(iii) a metallic sheet, comprising:
(A) an inner sheet surface shaped to form multiple protrusions, the inner sheet surface being exposed to an interior of the electrode, and
(B) an outer sheet surface shaped to define multiple depressions, the inner sheet surface facing away from the outer sheet surface, and
(iv) an adhesive, which fills the depressions and bonds the outer sheet surface to the layer of the electrically-conducting metal.
