PROBLEM TO BE SOLVED: To provide a structure for further improving various characteristics required for a stent.SOLUTION: A stent 11 comprises: multiple annular bodies 13 that have a wavy-line-shaped pattern, respectively, and are arranged side by side in an axial direction and multiple coil-shaped elements 15 that are arranged between the adjacent annular bodies 13 and extend windingly around an axis line. All top parts on a side where the wavy-line-shaped patterns of adjacent annular bodies 13 face each other are connected to one another by the coil-shaped elements 15. The top parts of the wavy-line-shaped patterns of the annular bodies 13 respectively have a bump-like part that includes: an extension section which extends in the axial direction and is wider than the respective coil-shaped elements 15 and an approximately-semicircular section which is formed at a tip thereof. The respective coil-shaped elements 15 are connected to the bump-like part.COPYRIGHT: (C)2015,JPO&INPIT【課題】ステントに要求される様々な特性をより向上させるための構造を提供する。【解決手段】ステント11は、波線状パターンを有し且つ軸線方向に並んで配置される複数の環状体13と、隣り合う環状体13の間に配置され軸線周りに螺旋状に延びる複数のコイル状要素15とを備え、隣り合う環状体13の波線状パターンの対向する側の頂部の全てが相互にコイル状要素15によって接続されている。環状体13の波線状パターンの各頂部に、軸線方向に延び且つコイル状要素15の幅よりも大きい幅を有する延長部分とその先端に形成された略半円形部分とを含む瘤状部が形成されており、コイル状要素15が瘤状部に接続されている。【選択図】図1
