Covered stent

The invention discloses a covered stent. The covered stent comprises a first covered section, a second covered section and a connecting section for connecting the first covered section and the secondcovered section, the connecting section comprises a deformation part, the axial size of the deformation part can be lengthened or shortened, and the connecting section further comprises an opening forcommunicating the inner surface and the outer surface of the covered stent. After the covered stent is implanted into a diseased blood vessel, the covered stent can isolate aneurysm, even aneurysm extending across branches, blood supply of branch blood vessels can be guaranteed, and meanwhile the covered stent can adapt to bent diseased blood vessels. 本发明公开了一种覆膜支架，包括第一覆膜段、第二覆膜段以及连接所述第一覆膜段和所述第二覆膜段的连接段，所述连接段包括变形部，所述变形部的轴向尺寸可伸长或缩短，所述连接段还包括连通所述覆膜支架内表面和外表面的开口。本发明的覆膜支架植入到病变血管后，能保证覆膜支架隔绝动脉瘤，甚至是隔绝延伸跨越分支的动脉瘤，且能保证分支血管的供血，同时，也能适应弯曲的病变血管。
