Abstract

A catheter assembly includes a catheter body (20) having a shaft portion (28) and an arm (30) portion, the arm portion having an adjustable defection in plane and out-of-plane relative to the shaft portion. An electrode disposed within the arm portion upon being energized is capable of ablating the entire cavo-tricuspid isthmus region of a heart without repositioning of the catheter body arm portion. An irrigation aperture located within the shaft portion of the catheter body supplies conductive biological fluid which acts as a virtual electrode for the ablation procedure.
