Product Overview
The document describes the Left Atrial Appendage Occluder System, highlighting its design features and advantages. Key features include dual bend delivery, superior coaxiality, and a harmonious combination of rigidity and flexibility. The system is designed to be safe and reliable, with a smooth proximal end to protect the endothelium.

Specifications
The product specifications include various models (YFDQ-20-1, YFDQ-24-1, YFDQ-27-1, YFDQ-31-1, YFDQ-35-1) with different diameters and heights. The delivery system includes components such as the pusher cable, delivery sheath, guiding sheath, and expansion tube.

Advantages
The occluder system offers a small endothelialization area, short endothelialization time, and low DRT risk, reducing the need for prolonged anti-coagulation. It is based on the predicate plug-type occluder from Watchman and follows the PASS principle for high operational stability. The system is suitable for the wider and shallower left atrial appendages common in Chinese patients.
