简要总结
Feasibility study arm to evaluate the safety of adding the left atrial linear connecting lesions of the Cox-Maze lesion set to the current RESTORE SR II IDE study procedure of performing pulmonary vein isolation, selected left atrial autonomic ganglionated plexi (GP) ablation, and optional left atrial appendage (LAA) excision/exclusion on a beating heart for patients with permanent or persistent Atrial Fibrillation (AF).

结局指标
主要结局
Feasibility of performing the operation by demonstrating the ability to consistently isolate the left and right pulmonary veins and to confirm conduction block across the roof, anterior and LAA linear lesions.
The primary safety endpoint will be determined by assessing the rate of serious adverse events.
