ABSTRACT:
For producing annular color marks on a spirally shaped catheter guide wire, a guide wire is selectively heated within a tempering range of 200.degree. C. to 360.degree. C. at the points provided for the color marks so that permanent temper colorations of the steel are left at said points. The advantage involved therewith is that color marks may be produced by neither removing nor applying material, and the contour of the guide wire is not changed. Further, no foreign material adhering to the guide wire may get into the body of the patient.
