Left Atrial Appendage Management

AtriCure’s AtriClip Products are the Most Widely Sold Left Atrial Appendage (LAA) Management Devices 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

 

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.

Hallmarks of AtriClip Device Excellence

Epicardial Exclusion
  • Implant is not in the blood stream
  • Ischemic injury electrically isolates the LAA
  • Atrophy and resorption of the LAA
Dynamic Closing Force
  • 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 ostia
Tissue Compression / Atraumatic
  • No cutting, non-piercing, and atraumatic compression reduces risk of tissue tearing and bleeding

The AtriClip devices are available on a variety of delivery systems optimized for open concomitant procedures as well as minimally invasive surgery, both through a thoracotomy and a port.
