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 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 camfered. In the case of rounded edges, the rounded edges can have fixed radii of about 0.002'' to about 0.008''.
摘要翻译：本发明涉及消融导管电极，其部分解决了射频消融期间组织烧焦的问题。本发明的电极组件包括从组件的内腔引导到组件的表面的通道，其中通道与外表面具有平滑的连接。这些平滑的连接包括圆形边缘或被凸起。在圆形边缘的情况下，圆形边缘可以具有约0.002“至约0.008”的固定半径。
