Abstract

A guide wire having a coil disposed over the guide wire, wherein the coil is integrally formed of a single wire and has regions of differing properties over its length. Some wire embodiments have longitudinally alternating layer segments having differing properties including radiopacity, lubricity, hydrophilicity, hemo-compatibility, flexibility, malleability, stiffness, and shape memory properties. A coil may have numerous distinct property segments, while being formed from only a single wire and requiring only two points for affixation to the guide wire.
