Abstract

PURPOSE:To accurately lead the tip of a flow guide wire to be inserted in a blood vessel to a target lesion, by providing a coil made of a fine metal wire which forms at least a part of a metal core. CONSTITUTION:A metal core 1C comprises a coil 2 made of a fine metal wire, e.g., tungsten, and a straight fine metal wire 3 made of, e.g., a resilient alloy, which is inserted into the coil 2. A synthetic resin cover 5 may be further provided on the surface of the metal core 1C. The synthetic resin cover 5 comprises a sphere 51, a flexible part 52, a taper 53 and a controller 54 in the direction of the rear portion from the tip. Since the straight fine metal wire 3 is used with the metal coil 2, a flow guide wire attains adequate hardness as well as resilience and is thus easily restored even if it is bent. The guide wire does not, therefore, cause the plastic deformation and is accurately led to a certain part in a blood vessel, thereby improving running stability.
