Abstract
An insertion instrument body includes a longitudinal metallic core portion, a distending portion and a power supply means. The metallic core portion is inserted into a lumen such as a blood vessel. The distending portion is fixed to an outer face of the metallic core portion. The power supply means heats the distending portion above a transforming temperature. The distending portion includes a cylindrical portion which is mountable on the metallic core portion; and a plurality of rod-shaped portions which are integrally formed in the cylindrical portion and which are made of a shape-memory material. The rod-shaped portion returns to an original shape by displacing in an intersecting direction with respect to a longitudinal direction of the metallic core portion. An electrical insulating layer is formed on an outer surface of the metallic core portion, and the electrical insulating layer is covered with a flexible sleeve. A power supply means is constituted of the metallic core portion, the flexible sleeve, a power source and a switch.
