The primary objective of this study is to evaluate the safety and effectiveness of the AtriCure CryoICE system in performing the Cox-Maze III lesion set, in conjunction with Left Atrial Appendage (LAA) exclusion using the AtriClip device.


The AtriCure CryoICE Ablation System is being studied to ablate cardiac tissue during surgery for the treatment of Persistent and Long-standing Persistent atrial fibrillation in open concomitant cardiac surgery.

The effectiveness of the device will be demonstrated by establishing that the device effectively eliminates persistent and long-standing persistent atrial fibrillation in a clinically significant proportion of treated patients.
