摘要： The present invention relates to improved ablation electrodes (10, 10') and catheter assemblies (12), as well as methods useful in conjunction with irrigated ablation catheters. An irrigated ablation electrode assembly (10, 10') includes a proximal member (18, 18') having an outer surface (22), an inner lumen (26, 26') and a proximal passageway (24). The proximal passageway (24) extends from the inner lumen (26, 26') to the outer surface (22) of the proximal member (18, 18'). The assembly (10, 10') further includes a distal member (20) having a distal end (30) and a distal passageway (28) extending from the inner lumen (26, 26') through the distal member (20) to the distal end (30). Embodiments of the present invention include an irrigated catheter assembly (12) configured to direct irrigation fluid to target areas where coagulation is more likely to occur to, among other things, better minimize blood coagulation and associated problems.

摘要： The invention relates to an ablation catheter which controls the temperature and reduces the coagulation of biological fluids on an electrode of a catheter, prevents the impedance rise of tissue in contact with the electrode, and maximizes the potential energy transfer to the tissue, thereby allowing an increase in the lesion size produced by the ablation. The electrode includes passages positioned to allow saline flow out of an inner cavity of the electrode. This fluid flow produces the desired cooling effect and is accomplished, for example, by saline irrigation flow with a valve element to block flow of blood into the inner cavity of the electrode.

摘要： An array of ring electrodes (38) or a wire electrode is mounted about the outside surface of the distal end (12) of the ablation catheter (22). Substantially all of the outer surface of each ring (38) or wire electrode is covered by an electrically insulating coating (44). The insulating surface coating (44) on each ring (38) defines a contoured opening (40) in the insulating surface coating (44) that exposes the conductive band or wire beneath. An array of contoured openings (40) are formed along a wire electrode. The insulating coating (44) mitigates potential edge effects that create hot spots and can result in unwanted tissue damage during an ablation procedure.
