Abstract
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″.
