Abstract
In a medical guide wire () formed by a helical hollow wire body which is arranged to retractably move against a needle tip (), the helical hollow wire body is formed into a wire-stranded helical hollow tube () by stranding a multitude of wire coil elements (). The wire coil elements () of a wire-stranded helical hollow tube () has a stranding angle (θ) of 55 degrees or less against an axial direction of the wire-stranded helical hollow tube (), and having an angle more than plus 2 degrees or an angle less than minus 2 degrees against a knife edge angle (θ) of the needle tip (), thus preventing the wire coil elements () from inadvertently hitched in the needle tip (), and thereby enabling manipulators to a smooth insertion and pull operation so as to improve a curability when the wire-stranded helical hollow tube () is retractably manipulated against the needle tip ().
