Integrated left atrial appendage occluder
By designing an integrated left atrial appendage occluder with an integrated sealing and anchoring structure, the problems of insufficient stability and recyclability in existing technologies are solved, achieving efficient occlusion and multiple recycling. It can adapt to different shapes of left atrial appendage structures, improving the safety and sealing stability of the occluder.

AI Technical Summary
Existing left atrial appendage occlusion devices have shortcomings in terms of stability, recyclability, and strength. In particular, the connectors of split-type devices are prone to detachment, and the integrated-type devices are prone to residual leakage and insufficient anchoring.
An integrated left atrial appendage occluder was designed, featuring an integrated sealing and anchoring structure. The sealing and anchoring parts are connected by an anchoring support beam, which has anchoring hooks along the direction of the delivery pipe. This design provides flexibility and recyclability. The anchoring support beam has a spiral structure, and the hooks are designed as a cross-shaped double hook to improve anchoring performance.
It improves the reliability and safety of the occluder, enhances sealing stability, can be recycled multiple times, adapts to different shapes of left atrial appendage structures, reduces residual shunt, and avoids adverse symptoms such as dislodgement and cardiac tamponade.
