Zusammenfassung: | To provide a stent for bypassing between luminal organs facilitating curving of hooking parts when reforming, while retaining strength of the hooking parts.SOLUTION: A stent 11 for bypassing between luminal organs, for bypass-connecting a luminal organ to another luminal organ comprises a plurality of hooking parts 51 each including a base end 52 connected to an end-side strut 33a, the strut located at least one end in the axial direction of a frame part 31, a tip end 54, the free end, and an intermediate part 53 extending along the longitudinal direction heading for the tip end 54 from the base end 52 and having a curved shape curving upward in an outer peripheral surface of the frame part 31. The intermediate part 53 is configured of two long portions 53a extending in the longitudinal direction, with them aligned in parallel in the circumferential direction of the frame part 31, and a plurality of lateral crosspiece portions 53b for connecting between the two long portions 53a.SELECTED DRAWING: Figure 6
【課題】フッキング部の強度を保ちながら、くせ付け時にフッキング部を湾曲させることが容易となる管腔臓器間バイパス用ステントを提供する。【解決手段】管腔臓器と他の管腔臓器とをバイパス接続するための管腔臓器間バイパス用ステント11は、フレーム部31の軸方向の少なくとも一方の端部に位置するストラットである端側ストラット33aに接続された基端部52と、自由端である先端部54と、基端部52から先端部54へ向かう長手方向に沿って延び、フレーム部31の外周面上方側へ湾曲する湾曲形状を有する中間部53と、を有する複数のフッキング部51を備える。中間部53は、フレーム部31の周方向に平行に並んで長手方向に延びる2つの長尺部53aと、2つの長尺部53a間を接続する複数の横桟部53bと、により構成されている。【選択図】図6 |
