摘要： In one embodiment, an irrigated catheter ablation apparatus comprises an elongated body having a distal end, a proximal end, and at least one fluid lumen extending longitudinally therein; and a plurality of segmented ablation electrodes on a distal portion of the elongated body. The electrodes are spaced from the proximal end and from the distal end of the elongated body by electrically nonconductive segments. The electrodes are spaced from each other longitudinally by electrically nonconductive segments. For each electrode that is longitudinally disposed next to one of the nonconductive segments, an edge is formed between an electrode end of the electrode and a nonconductive segment end of the nonconductive segment. A plurality of elution holes are disposed adjacent to the edges. A plurality of ducts establish fluid communication between the elution holes and the fluid lumen.
