Abstract
An irrigated finned ablation head that provides enhanced cooling. The irrigated finned ablation head comprises a plurality of radial fins that are distributed about a central axis and that extend axially from a common base. The plurality of fins are arranged to define a central passageway along the central axis, as well as a plurality of slots therebetween, the slots extending in an axial direction along the irrigated finned ablation head. In one embodiment, the central passageway extends through the irrigated finned ablation head, defining an opening at the distal extremity, with the slots extending from the base to the opening. In another embodiment, the irrigated finned ablation head includes a cap portion at a distal portion that is common to all the radial fins, so that the slots are terminated at the distal portion of the irrigated finned ablation head. The radial flow distribution along the central axis can be tailored by the configuration of the central passageway.
