Summary:To prevent or suppress deformation of a stent graft indwelled in an aneurysm when discharged, and to prevent or suppress distal embolization of a side branch in the aneurysm.SOLUTION: The present invention relates to an embolization material 10d capable of embolizing blood vessels connected to an aneurysmal cavity or capable of being left in the aneurysmal cavity, the embolization material including: a plurality of embolization bodies 11d formed in an abbreviated spherical shape; and flexible connecting members 14 for connecting each of a plurality of embolization bodies with one or two embolization bodies 11d at an interval, wherein each of the plurality of embolization bodies can be compressed and deformed so as to be fitted into blood vessels having diameters smaller than those of the plurality of embolization bodies.SELECTED DRAWING: Figure 21 【課題】吐出された際に動脈瘤内に留置したステントグラフトが変形することを防止または抑制するとともに動脈瘤内の側枝の遠位塞栓を防止または抑制する。【解決手段】本発明は、瘤空間に繋がる血管を塞栓可能又は瘤空間に留置可能な塞栓材１０ｄであって、略球状に形成された複数の塞栓体１１ｄと、複数の塞栓体のそれぞれを１つ又は２つの塞栓体１１ｄと間隔をあけて連結する柔軟な連結部材１４と、を有し、複数の塞栓体のそれぞれは、複数の塞栓体のそれぞれの直径よりも直径の小さい血管に嵌まり込むように圧縮変形可能である。【選択図】図２１
