The invention relates to an intracranial aneurysm blood flow guide support. The guide support comprises a main body part and an encryption part, wherein the main body part is of a cylindrical structure which is formed by weaving stent wires manually or by a weaving machine and is provided with an overlapping part through curling and shaping, the encryption part is arranged at the overlapping partfor mesh encryption, and the overlapping part and the encryption part cover an aneurysm opening. By means of the structural design, normal blood circulation of nearby side branch blood vessels is keptwhile blood flowing into the aneurysm is blocked, and in addition, due to the fact that axial stretching and retracting are reduced when the stent is pressed and held, the release difficulty is lowered. 本发明涉及一种颅内动脉瘤血流导向支架，该导向支架包括主体部分和加密部分，所述主体部分是由支架丝通过人工或编织机编织而成、并通过卷曲定型形成的带有重叠部分的圆筒状结构，并在所述重叠部分设置所述加密部分进行网孔加密，所述重叠部分及加密部分覆盖在动脉瘤口处。本发明通过结构设计实现在阻断流入动脉瘤内部的血流的同时，保持附近侧枝血管的正常的血液流通，此外该结构由于支架压握时的减少了轴向伸缩，降低了释放难度。
