AtriClip Device: The Most Widely Implanted LAAM Device Worldwide
The AtriClip devices are epicardially applied to the base of the left atrial appendage (LAA) during cardiac surgery procedures such that the LAA is permanently excluded from the left atrium of the heart. This exclusion eliminates blood flow and electrical communication of blood between the left atrium (LA) and the LAA and results in the electrical isolation of the LAA from the rest of the heart.1-4
AtriClip Device Features
Epicardial Exclusion
- Implant is not in the blood stream
- Ischemic injury electrically isolates the LAA
- Atrophy and absorption of the LAA
Continuous Dynamic Closing Pressure
- Continuous closing force maintains LAA exclusion throughout changes to the tissue caused by ischemia.
Parallel / Linear Closing
- Minimized occurrence of tissue folds with optimal apposition of tissue along long axis of LAA ostium
Tissue Compression / Atraumatic
- No cutting, non-piercing, and atraumatic compression reduces risk of tissue tearing and bleeding

LAA Exclusion Upgraded to Class IA Recommendation
In the latest release of the ACC/AHA/ACCP/HRS Guidelines for diagnosis and management of atrial fibrillation, LAA management was upgraded to the highest recommendation. Over the past two decades, AtriCure has worked tirelessly to develop a portfolio of AtriClip devices that permanently exclude the LAA. Now with a Class IA recommendation, AtriCure is more determined than ever to advocate for the value and importance of LAA exclusion.
