PROBLEM TO BE SOLVED: To provide a rope for a recovery mechanism, which can be inserted into a complicatedly formed part and recover a recovery target remaining in a blood vessel.SOLUTION: The rope has a configuration in which in the periphery of a multi-thread coil 2, a single wire material 3A is fitted in a valley 2B formed between coil raw wires 2A of the multi-thread coil 2 and the wire material 3A is wound spirally at predetermined intervals in the direction of an axial line L of the multi-thread coil 2, thereby configuring a convex recovery portion 10 made of the wire material 3A, and the recovery target Y is captured by a space region 11 formed between the outer peripheral surface of the convex recovery portion 10 and the outer peripheral surface of the multi-thread coil 2.COPYRIGHT: (C)2012,JPO&INPIT【課題】複雑形状な部位に挿入して血管等に残留する回収対象物を回収することができる回収機構用螺旋状ロープを提供する。【解決手段】多条コイル2の外周に、単一の線材3Aが該多条コイル2のコイル素線2A間に形成された谷部2Bに嵌め込まれ、該多条コイル2の軸線L方向へ一定の間隔を置いて螺旋状に巻回されることにより、線材3Aからなる凸状回収部10が構成され、該凸状回収部10の外周面と多条コイル2の外周面との間に形成された空間領域11で回収対象物Yを捕捉するようにした。【選択図】図1
