Abstract

An electrode for an electrophysiological ablation catheter including an electrode body extending along a longitudinal axis, the electrode body including an electrode outer surface for emitting high-frequency signals and/or for measuring physiological signals, a first attachment point on a first end, at which the electrode is attached to a first catheter shaft, an irrigation lumen extending parallel to the longitudinal axis and through which cooling agent may be directed out of the first catheter shaft and into the electrode, and which forms an opening at the first end of the electrode body, the opening connected to a lumen of the first catheter shaft, and at least one cooling-agent passage connected to the irrigation lumen, the cooling-agent passage situated at an angle to the longitudinal axis and forming first and second openings in the electrode outer surface, through which the cooling agent may be released into the surroundings, as cooling-agent flow.
