The present invention relates to ablation electrode assemblies. The present invention further relates to an irrigated ablation electrode assembly that includes a recessed portion that can improve fluid flow around the irrigated ablation electrode. The electrode includes an outer body portion having an outer surface, and an inner cavity defined within the outer body portion. The electrode further includes at least one passageway for fluid flow from the inner cavity to the outer surface of the body of the electrode. The passageway further defines an outlet on the external surface of the electrode, therein allowing the fluid to flow on and/or around the electrode surface. The outer surface of the electrode further includes a recessed portion. The outlet of the passageway is disposed at least partially within the recessed portion. The fluid that exits the passageway may flow within the recessed portion to improve irrigation of the electrode.
