摘要： An irrigated ablation catheter includes a shaft having a proximal end, a distal end, and an irrigation lumen therein. The catheter further includes an electrode assembly coupled to the distal end of the shaft. The electrode assembly includes an ablation electrode and a manifold. The manifold is coupled to each of the distal end of the shaft and the proximal end of the electrode. At least a portion of the manifold is constructed of a flexible material to allow the electrode assembly to deflect. The manifold includes a body, an inner cavity within the body configured for fluid communication with the irrigation lumen, and an irrigation port also within the body and configured for fluid communication with the inner cavity. The irrigation port extends from the inner cavity to the outer surface of the body, and is configured to allow for an irrigating fluid to be distributed from the manifold.

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 is pulsatile to increase turbulence, reducing areas of stagnant flow, and produces a desired cooling effect.

摘要： Embodiments of the present invention provide an irrigated catheter having irrigation fluid directed at target areas where coagulation is more likely to occur so as to minimize blood coagulation and the associated problems. In one embodiment, an irrigated ablation electrode assembly for use with an irrigated catheter device comprises a proximal member having at least one passageway for a fluid with an outlet disposed at an external surface of the proximal member; and a distal member connected with the proximal member and having an external surface. The distal member includes an electrode. The external surface of the proximal member and the external surface of the distal member meet at an intersection. The at least one passageway of the proximal member is configured to direct a fluid flow through the outlet toward a region adjacent the intersection.

摘要： The invention relates to electrodes used in ablation catheter devices, where the electrodes contain two or more thermal sensors at different positions within the electrode that are capable of detecting temperature differences along the external surface of the electrode. In preferred embodiments, the thermal sensors are separated by one or more thermal insulating members and the thermal sensors are positioned near the external surface of the electrode at about the same distance from the end of the electrode, so that temperature measurements can indicate the position of the electrode with respect to the tissue desired to be ablated.

摘要： The invention relates to ablation catheter electrodes that solve in part the problem of tissue charring during radiofrequency ablation. The electrode assemblies of the invention include passageways that lead from the inner lumen of the assemblies to the surface of the assemblies, wherein the passageways have a smooth conjunction with the outer surface. These smooth conjunctions comprise rounded edges or are chamfered. In the case of rounded edges, the rounded edges can have fixed radii of about 0.002″ to about 0.008″.
