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 method of making a metallic thin wire (1), one single metallic thin wire (2) is prepared to have a predetermined length with a middle portion of the one single metallic thin wire (2) as a fixed portion. Front and rear half portions of the one single metallic thin wire (2) are twisted with the front and rear portions being symmetrically located at both sides of the fixed portion, while at the same time, applying a tensile weight (W) to the front and rear half portions in the lengthwise direction. The one single metallic thin wire (2) is processed with a heat treatment to remove a residual stress from the one single metallic thin wire (2). Otherwise, the front and rear portions of the one single metallic thin wire (2) is primarily and secondarily twisted alternately under the tensile weight (W) applied in the lengthwise direction. This provides the metallic thin wire (1) with a high rotation-following capability and high torque transmissibility, thus enabling artisans to usefully apply the metallic thin wire (1) to a main wire component (25) of a medical tool and equipment.
