Abstract
A wire-stranded hollow coil body () has a multitude of coil line elements () stranded along a predetermined circular line to form a flexible wire tube having a central axial hollow portion (), the flexible wire tube is stranded under a strand-turn resistant load and heat treated to remove a residual stress upon formation so as to provide a high rotation-following capability and a high straightness. Further, a method provides a way to strand the coil line elements () under a strand-turn resistant load while heat treating the coil line elements ().
