• Study type: Interventional
• Intervention(s): The device is intended to reduce the risk of thromboembolism from the LAA in patients with non-valvular AF who are at increased risk for stroke and systemic embolism based on CHADS2 or CHA2DS2-VASc scores and are recommended for anticoagulation therapy. LAA occluder is implanted to LAA via transcatheter method.
