Abstract
The invention relates to a device, system and method to ablate a cardiac tissue. An ablation catheter system for drug refractory symptomatic paroxysmal atrial fibrillation (PAF). The system can include an elongated body; an electrode assembly comprising a shell configured with an inner chamber and a wall defining a proximal portion and a distal portion, the wall of the distal portion having at least one aperture; and a micro-element extending through the inner chamber between the proximal portion and the distal portion, the micro-element having a distal end received in the at least one aperture, the distal end being at least coextensive with an outer surface of the wall. The system is configured to achieve acute procedural PVI success for all patients of a predetermined patient population suffering from PAF.
