Ablation electrode assemblies 10 having a longitudinal axis 64 include an electrode core member 44; an electrode shell 46; and an irrigant distribution element 100. The electrode core member 44 comprises a thermal insulator and has a first end 48; a second end 50; and at least one irrigation passageway. The electrode shell 46 comprises an electrically conductive material, defines an inner volume, and has a first end 48; and a second end 50. The second end 50 of the electrode shell 46 is configured for connection to the first end 48 of the electrode core member 44. The electrode shell 46 is sufficiently flexible for deflection of the distal end 78 of the electrode shell 46 relative to the longitudinal axis 64 of the ablation electrode assembly 10. The irrigant distribution assembly comprises a first end; and a second end, wherein the second end of the irrigant distribution element 100 defines a circumferential irrigation port 106 between the irrigant distribution element 100 and the electrode core member 44. |
