This is a prospective, multi-center, randomized, open, parallel positive control, non-inferiority trail. The purpose of this study is assess the effectiveness and safety of the flow diverter(Ton-bridgeMT) by comparing with the data obtained by Tubridge for the endovascular treatment of intracranial aneurysms.


The Flow Diverter is an intracranial implant designed to be placed in a parent artery so as to divert blood flow away from an aneurysm. This clinical trial is carried out in 14 research centers. The subjects are randomly divided into the experimental group using flow diverter(Ton-bridgeMT) and the control group using Tubridge at a ratio of 1:1.
