Study purpose and design
The Sphere-360™ European study was a prospective, single-arm, multicenter trial designed to evaluate safety, effectiveness, and lesion durability of the Sphere-360™ catheter when used for the treatment of symptomatic drug refractory paroxysmal atrial fibrillation (PAF) patients (n = 100). Results of this study are outlined in the manuscript ”One-year outcomes of a conformable single-shot pulsed-field ablation catheter for the treatment of paroxysmal atrial fibrillation” linked below.
