PROBLEM TO BE SOLVED: To provide an indwelling aid implement used for a fistula catheter to stabilize holding of a member for forming a bumper-shaped intracorporeal fixed part.SOLUTION: The indwelling aid implement 60 is formed with a cylindrical body part 60A on the distal end side. The cylindrical body part 60A includes a distal end side holding part 63 holding one axial end side of the intracorporeal fixed part B with the cylindrical body part 60A inserted therein, and a proximal end side holding part 64 formed on the proximal end side rather than the distal end side holding part 63 to hold the other axial end side of the intracorporeal fixed part B with the cylindrical body part 60A inserted therein, so as to be axially movable on the outer peripheral surface.COPYRIGHT: (C)2012,JPO&INPIT【課題】瘻孔カテーテルに用いられ、バンパー形状の体内固定部を形成する部材の保持の安定化を図るようにした留置補助具を提供する。【解決手段】留置補助具60は、筒状本体部60Aが、先端側に形成され、筒状本体部60Aが挿入された体内固定部Bの軸方向の一端側を保持する先端側保持部63と、先端側保持部63よりも基端側に形成され、筒状本体部60Aが挿入された体内固定部Bの軸方向の他端側を外周面で軸方向に移動可能に保持する基端側保持部64と、を備えたものである。【選択図】図1
