ABSTRACT:
A cardiac ablation catheter system incorporates several different, but complementary features. The catheter includes a virtual electrode section for transferring ablation energy to form a linear lesion in cardiac tissue. The distal tip of the catheter shaft is provided with a tip electrode to perform spot ablations. The distal end of the catheter, generally including the virtual electrode section, may be operably formed into a curve with a variable radius of curvature.
