Occlusion device
By employing a woven mesh structure and a denser zone design on the fixation part of the left atrial appendage occluder, the problem of detachment caused by insufficient contact between the fixation part and the atrial appendage was solved, achieving better anchoring effect and stability.

AI Technical Summary
The fixation part of the existing left atrial appendage occluder is prone to detachment when the contact area with the atrial appendage is insufficient, and the anchoring structure design has not effectively solved this problem.
The fixing part is made of a mesh structure woven from braided yarn, with multiple radially extending wings. A denser zone is set on the mesh surface at the near and far ends of the fixing part to increase the density of the braided yarn, forming a dense and non-dense zone, thereby enhancing the anchoring performance.
It increases the contact area and anchoring stability between the occlusion device and the auricle, reduces the risk of detachment, adapts to the irregular inner wall morphology of the auricle, and enhances radial support and flexibility.
