More Information
Summary:An ablation electrode assembly is provided with improved irrigation cooling of the assembly and ablation site. The assembly includes a proximal end configured to be coupled to a catheter shaft and a distal end configured to deliver ablation energy to tissue. The assembly further includes a fluid manifold extending from the proximal end to the distal end and configured to fluidly communicate with a fluid lumen in the catheter shaft. The fluid manifold defines an axial passageway centered about a longitudinal axis extending in the longitudinal direction of the assembly. The axial passageway has a distal end terminating prior to the distal end of the electrode assembly. The assembly further includes means for creating turbulence in fluid exiting the first axial passageway.
