Abstract
A method for producing an in-vivo indwelling member includes a step of winding a metal wire () to form a primary coil (-), a step of giving the primary coil (-) a shape to form a secondary coil (-), and a step of inserting the secondary coil (-) into an inner hollow section () of a shaping mold (). The secondary coil (-) includes different patterns such as a helical shape (--), a linear shape (), and a circular arc shape (-). When the secondary coil (-) is pushed into the inner hollow section (), the secondary coil (-) makes contact with the inner wall surface of the inner hollow section (), and a portion between different patterns is randomly curved. Accordingly, the in-vivo indwelling member has a three-dimensional structure that corresponds to the shape of the inner hollow section (). The in-vivo indwelling member is less likely to deviate from the inside of an aneurysm when released into the aneurysm.
