Abstract
The present invention relates to improved ablation electrodes and catheter assemblies, as well as methods useful in conjunction with irrigated ablation catheters. Embodiments of the present invention further relate to an irrigated catheter having irrigation fluid directed at target areas where coagulation is more likely to occur to help minimize blood coagulation and the associated problems. The present invention further relates to an ablation electrode having an outer body with a proximal portion and a distal portion an inner cavity and at least one passageway that extends to an opening on the outer surface of the electrode, wherein the passageway is directed towards the proximal portion and/or proximal end of the electrode forming an acute angle with a longitudinal axis of the electrode.
