ABSTRACT:
The invention relates to a variety of catheters provided with an elongate body with an electrically conductive first end. Wherein through said elongate body at least one conductive wire extends which is connected to an electrode. The electrode is coupled to said first end and an irrigation means (e.g. a channel, duct, tube, etc.) for feeding an irrigation fluid through said elongate body, where said irrigation means is provided, in, on, near, through, or adjacent said first end with at least one outlet opening, while said irrigation means is at least partially thermally insulated from said first end. Optionally a temperature sensor couples to the first end.
