摘要
It is an object of the present invention to provide an in vivo indwelling member which, while having a shape complicatedly curved in various directions and easily spreading inside an aneurysm or the like, is capable of being adhered to an inner wall of the aneurysm or the like to be prevented from falling off therefrom, is also capable of further improving an indwelling density, and is capable of maintaining good operability. It is another object of the present invention to provide an in vivo indwelling member placement device provided with the in vivo indwelling member. Shapes of two or more three-dimensional portions (middle solid 4A, large solid 4B) are provided in a primary coil 11. Each three-dimensional portion is formed by continuously providing at least four curved parts (51a to 51e/52a to 52f) over four planes. Normal directions of the four planes each have a relationship perpendicular to a predetermined common axis (a1/a2) direction. Each of the at least four curved parts (51a to 51e/52a to 52f) is formed on any of the respective planes of a quadrangular virtual cylindrical body as seen from the common axis (a1/a2) surrounded by the four planes.
