简要总结
This study is a post-marketing clinical study of the Lattice Flow-Diverting Dense-Mesh Stent. It plans to enroll 280 patients, who will be treated for unruptured intracranial aneurysms using the Lattice Flow-Diverting Dense-Mesh Stent. Patients will be followed up at 12 months after device implantation, and data including the Raymond classification of the target aneurysms, the occurrence of complications, and whether complications result in neurological deficit symptoms will be collected and assessed. Through the above indicators, the clinical safety and efficacy of the product will be evaluated.
