Prospective, Non-randomized, Safety and Efficacy Study of a New Occluder Design for Minimally Invasive Closure of the Left Atrial Appendage (LAA) in Patients With Atrial Fibrillation

Prospective, Non-randomized, Safety and Efficacy Study of a New Occluder Design for Minimally Invasive Closure of the Left Atrial Appendage in Patients With Atrial Fibrillation

This is a prospective, non-randomized, study of the safety and efficacy of the Occlutech® LAA occluder indicated for percutaneous LAA closure in adult male or female patients with atrial fibrillation. Safety and efficacy will be assessed at day 1, 30 and 90, and after 1 year following implantation of an Occlutech® LAA Occluder.

Inclusion Criteria:

• Large PFO with significant atrial septal aneurysm
• Planned ablation procedure within 30 days of Occlutech LAA occluder® implant
• Resting heart rate > 110 bpm
• Allergy to Nitinol, which is a result of nickel and/or titanium allergies
• Stroke/TIA within the last 30 days
• Thrombocytopenia, thrombocytosis, leukopenia, or anemia
