摘要:
A guidewire has a distal-most end portion that retains its desired shape. The guidewire includes a first brazing member joining a distal end of a core shaft to a distal end of an outer coil, and a second brazing member provided adjacent to and on a proximal side of the first brazing member. The guidewire also includes an outer coil surrounding an outer periphery of the core shaft, and an inner coil provided between the outer coil and the core shaft. The second brazing member is provided between the outer coil and the inner coil, but is not provided between the inner coil and the core shaft. The melting point of the first brazing member is higher than the melting point of the second brazing member.
