In-vivo indwelling member and in-vivo indwelling member arrangement apparatus provided with the in-vivo indwelling member

摘要

The present invention has a shape that is curved in various directions and is easy to spread inside an aneurysm, etc., can be in close contact with the inner wall of an aneurysm, etc., and can be prevented from falling off, and the indwelling density can be further improved. It is an object of the present invention to provide an in-vivo indwelling member that can maintain good operability and an in-vivo indwelling member arranging device including the in-vivo indwelling member. The primary coil (11) is provided with two or more solid parts (medium solid 4A, large solid 4B), and each solid part has at least four shape parts (51a to 51e / 52a to four planes). 52f) is a three-dimensional part configured in a continuous manner, and the normal directions of the four planes are all orthogonal to the predetermined common axis (a1 / a2) direction, and at least these four curved portions (51a to 51a) 51e / 52a to 52f) are formed in any one of the surfaces of the quadrangular virtual cylindrical body as viewed from the common axis (a1 / a2) surrounded by the four planes.
