摘要： An irrigated catheter directs irrigation fluid at an angle generally parallel with a proximally tapered portion of a tip electrode for improved electrode surface cooling. An irrigated ablation electrode assembly (11) for an irrigated catheter device comprises a proximal member (20) having at least one fluid passageway (24) with an outlet disposed at an external surface of the proximal member; and a distal member (18) connected with the proximal member and having an external surface, the distal member including an electrode. The distal member has a tapered proximal surface portion narrowing toward the proximal member at an angle relative to a longitudinal axis of the distal member. The passageway of the proximal member directs a fluid flow through the outlet (22) in a distal direction at an angle substantially equal to the taper angle thus providing external flow generally parallel to the tapered proximal portion of the distal member.
