An ablation system for ablating cardiac tissue within a chamber of the human heart including a guiding introducer system, a rail, one end of which is contained within the guiding introducer system, and an ablation catheter system which is supported by the guiding introducer system. The guiding introducer system may be a single or multiple guiding introducers. The ablation system may include a slotted sheath which passes over the rail which supports the ablation catheter. A process is disclosed for ablation of cardiac tissue to form a linear lesion utilizing a rail catheter ablation and mapping system which includes a guiding introducer, a rail and an ablation catheter system advanced over the rail.
