FDA Product Code PZX: Left Atrial Appendage Clip, Implantable

Left atrial appendage occlusion reduces stroke risk in patients with atrial fibrillation who cannot take anticoagulants. FDA product code PZX covers implantable left atrial appendage clips.

These devices are applied epicardially to mechanically occlude the left atrial appendage from the outside of the heart, preventing thrombus formation in this common site of embolic stroke in AF patients. They represent an alternative to catheter-based endovascular LAA closure.

PZX devices are Class II medical devices, regulated under 21 CFR 878.4300 and reviewed by the FDA Cardiovascular panel.

Leading manufacturers include AtriCure, Inc..
