Abstract: In a medical guide wire 1, a flexible core wire 2 is made of austenitic stainless steel wire treated with a solid solution procedure, and drawn with a whole cross sectional reduction ratio as 80%-97.6%. The core wire 2 and a helical spring body 3 are welded by a welding member 4. The welding member 4 is made of eutectic alloy having a melting temperature ranging from 180° C.-495° C. Upon welding the helical spring body 3 to the core wire 2 which is made of the stainless steel metal, the procedure prevents the medical guide wire 1 from sacrificing its mechanical strength by significantly reducing the thermal influence on the core wire 2 and the helical spring body 3.

Abstract: In a medical guide wire 1, a helical spring body 3 is made of austenitic stainless steel wire treated with a solid-solution procedure, and tightly drawn with a whole cross sectional reduction ratio as 90%-99.5%. A metallic wire element of the helical spring body 3 is heat treated at low temperature within a range in which a tensile rupture strength of the helical spring body 3 rapidly increases by partly or totally making use of a conductive heat generated when a core wire 2 and the helical spring body 3 are in part bonded by means of a welding member 4. This makes it possible to improve a mechanical strength property, especially a fatigue-resistant property against a repetitive bending action of the helical spring body 3.

Abstract: In a medical guide wire 1, a flexible core wire 2 is made of austenitic stainless steel wire treated with a solid solution procedure, and drawn with a whole cross sectional reduction ratio as 90%-97.6%. Each time when the core wire 2 is subjected to a series of mechanical procedures, the core wire 2 is heat treated repetitively at low temperature subsequent to the mechanical procedures to improve a tensile strength characteristic of the core wire 2. The core wire 2 is twisted under the low heat treatment. Effectively used is a heat generated from a synthetic layer 6 when coating the layer 6 on the helical spring body 3. This makes it possible to increase the characteristic of the tensile strength of the core wire 2 with its thermal conductivity taken into consideration. Upon improving the tensile strength of the core wire 2, optimal conditions are achieved by observing a relationship between the tensile strength and the temperature which the core wire 2 exhibits when tightly drawn as a wrought-out procedure.
