ABSTRACT:
An intravascular guidewire is provided having a central section which typically comprises the majority of the length of the guidewire, and terminal sections which are of lesser diameter than the diameter of the central section. Each of the terminal sections is of differing physical characteristics relative to each other, to exhibit differing dynamic characteristics during use. This provides the user with a greater variety of guidewire performance characteristics, depending upon which end of the guidewire is used as the distal end of advancement.
