Claim 0:
1. An ablation electrode for a catheter, the ablation electrode comprising:
a supporting structure comprising a dome shaped distal portion at a catheter tip; and
a flexible electrically-insulating substrate comprising an inner surface and an outer surface in which an outer layer of an electrically-conducting metal covers at least part of the outer surface and an inner layer of the electrically-conducting metal covers at least part of the inner surface and is bonded to the dome shaped distal portion of the supporting structure, the flexible electrically-insulating substrate being shaped to define:
(i) multiple narrower channels passing between the inner surface and the outer surface with respective columns of the electrically-conducting metal that fill the multiple narrower channels so as to connect the outer layer to the inner layer, and
(ii) one or more wider channels passing between the inner surface and the outer surface with a layer of the electrically-conductive metal that plates the wider channels to connect the outer layer to the inner layer to provide for a fluid passageway for passage of irrigation fluid therethrough.
