The AtriClip Left Atrial Appendage Exclusion (LAAE) System is indicated for the exclusion of the heart’s Left Atrial Appendage (LAA), performed under direct visualization and in conjunction with other cardiac surgical procedures.
Isolation of Appendage
The AtriClip family of devices are the only Left Atrial Appendage Management (LAAM) devices clinically proven to provide both mechanical1 and electrical isolation of the LAA.2
Class IA Recommendation
LAAM is now supported with Class IA recommendations from ACC/AHA and STS. This is based on decades of experience and clinical data supporting the efficacy and safety of the AtriClip System.


A Simplified Approach to LAAE
AtriCure’s AtriClip devices are the most widely implanted LAAM devices in the world, providing a permanent solution to LAA exclusion during cardiac procedures.
Over 20 Years of Innovation in LAAM
AtriCure has worked tirelessly to create a line of AtriClip devices that permanently exclude the LAA.

MRI SAFETY INFORMATION:
MR CONDITIONAL
The LAA Exclusion System Clip is MR Conditional. A patient with the LAA Exclusion System Clip may be safely scanned under the following conditions. Failure to follow these conditions may result in injury to the patient:
- Nominal Values of Static Magnetic Field: 1.5-Tesla or 3.0-Tesla
- Maximum Spatial Field Gradient: 40 T/m (4,000 gauss/cm)
- Type of RF Excitation: Circularly Polarized (CP) (i.e., Quadrature Transmission)
- Transmit RF Coil Information: There are no transmit RF coil restrictions.
- Operating Mode of MR System: Normal Operating Mode
- Maximum Whole Body Averaged SAR: 2-W/kg (Normal Operating Mode)
- Limits on Scan Duration: Whole body averaged SAR of 2-W/kg for 60 minutes of continuous RF exposure (i.e., per pulse sequence or back-to-back sequences/series without breaks)
- MR Image Artifact: The presence of this implant produces an imaging artifact. Therefore, carefully select pulse sequence parameters if the implant is located in the area of interest.
