ABSTRACT:
A method of treating cardiac arrhythmia, including guiding a distal end portion of a catheter, the distal end portion having a distal tip and accommodating an elongated configuration of ablation electrodes, from the inferior vena cava into the right atrium of a human heart, guiding the distal end portion from the right atrium into the right ventricle of the heart, deflecting the distal tip into a hook configuration, pulling the catheter towards the inferior vena cava until the hook configuration engages the tricuspid annulus of the heart and the configuration of electrodes engages the isthmus of tissue between the tricuspid annulus and the inferior vena cava of the heart, and activating the configuration of electrodes to produce a substantially continuous lesion on the isthmus of tissue.
