A color coding is applied to medical guide wires by coloring portions of the guide wire to distinguish similar guide wires and guide wire portions from a particular manufacturer. The metallic elongate core can be colored using various methods such as electrochemical processes, sputtering, electroplating, and laser inducing microstructures to alter the surface characteristics of the elongate metallic core. Alternatively, the outer layer of the guide wire can be color coded by using non-standard colors or by introducing a colored band on the guide wire.

Color coded guide wire and methods of making same

A guide wire includes an elongate core section and a flexible member disposed on the distal end, the flexible member including a first wire wound into an inner helical coil in a first direction and a second wire wound into an outer helical coil wrapped about the first helical coil in the opposite direction. The two combined helical coils add stiffness and torque transmission to the guide wire without sacrificing tactile feedback.
