    • A stent includes a lattice defining a substantially cylindrical configuration having a proximal end portion and a distal end portion, and a middle portion between the proximal end and the distal end. The lattice being moveable from a crimped state to an expanded state, and a plurality of adjacent hoops. Each hoop has a plurality of adjacent loops. Additionally, the stent further includes a plurality of bridges connecting adjacent hoops and a plurality of extensions on the lattice. Each of the hoops and bridges define a cell. The proximal end portion and the distal end portion of the lattice have at least one cell respectively and the middle portion of the lattice has at least one cell. The plurality of extensions are on the middle portion of the lattice. The plurality of extensions are cantilevered projections from the bridges and/or hoops of the lattice. The plurality of extensions are movably deformable in a direction away from the lattice, for example, at least some of the extensions are movably deformable in a direction away from the bridges and at least some of the extensions are movably deformable in a direction away from the hoops.
    • 支架包括限定具有近端部分和远端部分的基本上圆柱形构造的格子,以及近端和远端之间的中间部分。 格子可以从卷曲状态移动到展开状态,并且多个相邻的环。 每个箍具有多个相邻的环。 此外,支架还包括连接相邻环的多个桥和在晶格上的多个延伸部。 每个环和桥定义一个单元格。 晶格的近端部分和远端部分分别具有至少一个电池,并且晶格的中间部分具有至少一个电池。 多个延伸部位于格子的中间部分。 多个延伸部是从网格的桥和/或环的悬臂突起。 所述多个延伸部在远离格子的方向上可移动地变形,例如,至少一些延伸部在远离桥梁的方向上可移动地变形,并且至少一些延伸部分沿着远离网格的方向可移动地变形 箍
