Abstract

The invention is directed to a guide wire having at least two different polymeric jackets that impart different handling characteristics to the portions of the guide wire they surround. Preferably, the guide wire may have jackets of different grades of polymer, such as polyurethane 55D and 90A. Alternatively, the guide wire may have jackets of different types of polymers such as polyurethane and polytetrafluoroethylene, or may have a single polymeric jacket with continuously varying properties along its length. The invention also comprises methods of making such guide wires.
