The first patient has been treated in the Boston Scientific Corporation ZERO AF clinical trial to evaluate the safety and effectiveness of the Blazer open-irrigated temperature ablation Catheter in patients with symptomatic, drug refractory paroxysmal atrial fibrillation. This international, multi-center study will include up to 33 sites in the United States, Europe and Asia-Pacific, and as many as 472 patients. The results of the ZERO AF trial are expected to be used to support a U.S. Food and Drug Administration (FDA) regulatory submission for a paroxysmal atrial fibrillation indication.
