<P>PROBLEM TO BE SOLVED: To provide a medical guide wire which prevents excessive development of prolapse and has high safety. <P>SOLUTION: The medical guide wire 1A includes a core shaft 2, a coil body 3A and a safety wire 5A. The tip 2a of the core shaft 2 is moved apart in the base end direction from the leading end part 4 formed in the coil part 3A, while a first brazing part (connection part) 6 which is connected to the safety wire 5A and the coil body 3A is formed at the tip 2a of the core shaft 2. A function of developing the prolapse easily to prevent blood vessel perforation can be given to the side closer to the tip side than the first brazing part (joint part) 6, while a function of preventing the excessive development of the prolapse can be given to the side closer to the base end side than the first brazing part (joint part) 6 by raising the rigidity of that side more sharply than that of the tip side. <P>COPYRIGHT: (C)2012,JPO&INPIT |
