摘要:
A branched stent graft, a convey system comprising thereof and manufacturing method thereof, the branched stent graft includes a main body (100) and a side branch (200), at least a portion of a lowermost stent section of the side branch (200) closest to the main body (100) is not stitched to the cover of the side branch from a lower end to an upper end, the at least a portion of the lowermost stent section is located on a side of the side branch corresponding to a folding direction of the side branch. After deployed, the branched stent graft has an effective supporting force at the base portion of the side branch. In addition, during the deployment of the stent, the side branch can expand to a maximal extent even when the positioning is slightly inaccurate. Further, vascular stenosis or occlusion will not be caused even when subsequent endothelialization occurs.
