The aneurysm blockade device, in order to cover the neck of the aneurysm of the blood vessel, is arrangement possible inside the brain blood vessel. The tubular element which possesses the tube cavity which is surrounded in the blockade side wall which includes the plural gaps is included in the device. The gap although the flow of the blood to inside the aneurysm which passes by the side wall from the blood vessel is made to block, at least partly is sufficiently small, but it is open-ended according to the tide way with the tube intracavitary first territory and the second territory outside the tube cavity, the fluid flow because of this passes by the side wall with the blood vessel and the lateral branch blood vessel is made possible.< Selective figure >Figure 4B動脈瘤閉塞デバイスは、血管の動脈瘤のネックを覆うように脳血管内に配置可能である。デバイスには、複数の間隙を含む閉塞側壁に囲まれた管腔を有する管状要素が含まれる。間隙は、血管から側壁を通る動脈瘤内への血液の流れを、少なくとも部分的に閉塞させるのに充分に小さいが、管腔内の第一領域と管腔外の第二領域との間の流圧差に応じて拡張可能であり、これにより血管と側枝血管との間の側壁を通る流体の流れを可能とする。【選択図】図4B
