Abstract
In a medical guide wire, a front end of a core member is tapered off or diametrically reduced successively as it approaches a leading end tip to form a frustoconical configuration. A helical spring and the core member are spaced to form a non-integral zone extending at least 20 mm from a front end of the diameter-reduced front end portion. An inner circumference of the helical spring and an outer circumference of the core member are concentrically secured to form a plurality of securement points aligned in the lengthwise direction at regular spans so as to enable an operator to steer the guide wire with an improved rotation-following capability.
