Abstract:
1. An irrigation catheter, comprising: a tubular member comprising a non-conductive material having a proximal end and a distal end, the tubular member having a plurality of lumens extending from the proximal end to the distal end of the tubular member, one lumen of the plurality of lumens being an irrigation lumen; at least one ablation electrode arranged on the tubular member proximally of the distal end of the tubular member, the at least one ablation electrode having at least one irrigation opening defined in the at least one ablation electrode; and a fluid-carrying formation arranged in the tubular member, the fluid-carrying formation located between an inner surface of the at least one ablation electrode and an outer surface of the tubular member, the fluid-carrying formation being in fluid flow communication with the irrigation lumen of the tubular member for conveying fluid from the irrigation lumen to the at least one irrigation opening of the at least one ablation electrode; and wherein the at least one ablation electrode is mounted on the tubular member in a fluid-tight manner and is configured to inhibit escape of fluid past an edge of the at least one ablation electrode.
