1. An ablation catheter system for ablation of epicardial tissue of a heart of a subject, said ablation catheter system comprising:

  • an ablation catheter, said ablation catheter comprising a distal end, a proximal end, and a longitudinal wall there between;

    a plurality of electrodes in communication with said ablation catheter;

    a catheter steering mechanism configured to orient said ablation catheter about the heart;

    a catheter control device, wherein said catheter control device is configured to manipulate said catheter steering mechanism;

    one or more distal irrigation apertures at said distal end of said ablation catheter, said one or more distal irrigation apertures are in communication with one or more irrigation lumens extending longitudinally toward said proximal end of said ablation catheter;

    one or more distal suction apertures at said distal end of the ablation catheter, said one or more distal suction apertures are in communication with one or more suction lumens extending longitudinally toward said proximal end of said ablation catheter;

    a sheath, said sheath comprising a distal end, a proximal end, and a longitudinal wall there between, and wherein said sheath is adapted for receiving said ablation catheter therein;

    a sheath steering mechanism configured to orient said sheath about the heart; and

    a sheath control device, wherein said sheath control device is configured to manipulate said sheath steering mechanism;

    wherein, said plurality of electrodes comprise at least one of;

    an anode and a cathode,a plurality of electrodes arranged in a circumferential array around said distal end of said ablation catheter, anda plurality of electrodes longitudinally separated on said distal end of said ablation catheter, andwherein, at least one of said one or more distal irrigation apertures or said one or more distal suction apertures comprises a plurality of apertures arranged in a circumferential array around the distal end of the ablation catheter.
