发明名称 IRRIGATED ABLATION CATHETER WITH MULTI-SEGMENTED ABLATION ELECTRODES
摘要 PROBLEM TO BE SOLVED: To provide an irrigated catheter ablation apparatus with a plurality of segmented ablation electrodes.SOLUTION: An irrigated catheter ablation apparatus 10 comprises: an elongated body having a distal end 12, a proximal end, and at least one fluid lumen 13 extending longitudinally therein; and a plurality of segmented ablation electrodes 16 on a distal portion of the elongated body. The electrodes are separated from the proximal end and the distal end of the elongated body by electrically nonconductive segments 18. The electrodes are separated from each other longitudinally by the electrically nonconductive segments. For each electrode that is longitudinally disposed next to one of the nonconductive segments, an edge 20 is formed between an electrode end of the electrode and a nonconductive segment end of the nonconductive segment. A plurality of elution holes 22 are disposed adjacent to the edges. A plurality of ducts 24 establish fluid communication between the elution holes and the fluid lumen.
