ABSTRACT:
A fabrication process for a guidewire. A guidewire core is provided by drawing down a metal wire in stages. The wire is drawn through a first die to produce a first diameter wire. This first diameter wire is then partially drawn through a second die to provide a second, reduced diameter wire segment at one end of the core wire.
