A high performance coil over-core guide wire. The guide wire incorporates a nickel-titanium core with a stainless steel coil to provide a wire with improved kink resistance and good pushability.

High performance coil wire

Disclosed is a guide wire having a coil surrounding a core of the guide wire and a stiffness transition element. The stiffness transition element is configured to provide a smooth stiffness transition from the distal end of the guide wire to the coil and/or the core of the guide wire. The stiffness transition element may be formed of any medical grade polymer.

Guide wire stiffness transition element

A multi-layered guide wire that uses separate layers to achieve desired guide wire characteristics. Each of the layers may enhance one or more of the desired guide wire characteristics, with the combination of layers providing the desired combination of guide wire characteristics. Each of the layers may be provided over the entire guide wire, or only over selected portions of the guide wire. Further, selected layers may be co-extruded over the guide wire, which may reduce the manufacturing costs associated therewith.
