PROBLEM TO BE SOLVED: To provide an in-vivo indwelling member that has thinness similar to the conventional one at the time of being guided by using a transportation catheter and is capable of expanding the member's volume greater than that before transportation after the member has been inserted into a swelling such as an aneurysm, and provide a manufacturing method capable of simply manufacturing the in-vivo indwelling member.SOLUTION: An in-vivo indwelling member includes: a cylindrical first coil formed by a first wire wound with intervals; a cylindrical second coil formed by a second wire wound along gaps of the first wire spaced at the intervals; and an expansion member that has a part provided on the cylindrical outer surface side of the first coil and provided on the cylindrical inner surface side of the second coil and extends along the second coil's longer axis.SELECTED DRAWING: Figure 1 |
