The micro catheter inside the blood vessel which possesses the basic edge side shaft which consists of the hyposulfite tube which has the movement section

摘要

The catheter inside the blood vessel which has the metallic conduit of the basic edge side whose rigidity is high and the tube of the advanced side which possesses flexibiility (10). For example as for portion of the point of the metallic conduit, the air gap which makes the rigidity of the metallic conduit low (22) (the helical slot and the like) it is removed in order to form. The basic end of the tube of the advanced side which possesses flexibiility is arranged inside the aforementioned air gap, connects securely, makes fuse flexibiility of the tube of rigidity and the advanced side where the metallic conduit of basic edge side is high, without increasing the external form that much.
