PROBLEM TO BE SOLVED: To provide a mold for manufacturing an in-vivo indwelling member in which the in-vivo indwelling member capable of being stably arranged in lumps, e.g., such as aneurysm can be simply made.SOLUTION: A mold for manufacturing an in-vivo indwelling member is provided for obtaining the in-vivo indwelling member having a secondary shape of a three-dimensional arrangement by further incorporating a primary coil formed of strands. The mold includes a variable member that can be changed into an assembled state and an expanded state, and the variable member is a mold having a first surface where the primary coil is disposed and a holding part for disposing the primary coil in a predetermined shape on the first surface.COPYRIGHT: (C)2015,JPO&INPIT【課題】例えば動脈瘤等の瘤内で安定的に配置することが可能な生体内留置部材を簡便に作製することが可能な生体内留置部材製造用の型を提供すること。【解決手段】素線で形成される一次コイルを更に賦形して三次元配置の二次形状を有する生体内留置部材を得るための生体内留置部材製造用の型であって、該型は、組立状態と展開状態とに変形可能な可変部材を備え、該可変部材は、前記一次コイルが配置される第1面と、該第1面に前記一次コイルを所定形状に配置するための保持部とを有する型。【選択図】図3
