摘要： In a wire-stranded hollow tube (1), a plurality of metallic wires (8) preformed with a predetermined forming rate are twisted along a circular line into a careless hollow configuration. When twisting the metallic wires (8), the neighboring metallic elements (1a, 1a) are subjected to compression with no gap between the neighboring metallic elements (1a, 1a). This increases a contact pressure between the neighboring metallic elements (1a, 1a) to attain a good tightness with a good circularity and diametrical uniformity secured therebetween, thus preventing the wire-stranded hollow tube (1) from inadvertently collapsing. A tightness is strengthened between the neighboring metallic elements (1a, 1a) when the metallic elements (1a, 1a) of different helical pitch are used. By applying the wire-stranded hollow tube (1) to a medical guide wire, a quick torque response and a good torque transmissibility are ensured which lead to a good manipulatability with a favorable follow-on capability.

摘要： 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.

摘要： In a medical guide wire, a core line securement portion (11) is provided in which the core wire (2) is fixed to an inner side of the helical coil body (3) so as to form a top leading end portion (10) between the core line securement (11) and the head plug (4). A flat plane structure (13) is formed in which the core wire (2) of the top leading end portion (10) gradually changes through stepped portions (S) so that the core wire (2) progressively reduces its thickness stepwisely while successively increasing its breadth stepwisely as approaching a foremost distal end of the top leading end portion (10). This provides an improved flexibility, sensitivity, torsibility and torque transmissibility with the flat plane structure (13) so as to be accessible to the diseased area with a high detective and ablative ability.

For this purpose, a core elongation has a torsional rigidity coefficient of 16 or less in terms of K ×103. A helical spring has a helical diameter-to-line diameter ratio in the range of 2.5˜3.5. Where the torsional rigidity coefficient is a divided value of (a maximum torsional stress based on a torsional moment to which the core member is subjected)/(the torsional moment to which the core member is subjected).

摘要： 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.
