Abstract
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.
