ABSTRACT:
Guidewire comprising an elongated core element manufactured from a martensitic alloy that is heat-treated to render a fully hardened core throughout its cross sectional area. The core has a constant taper or step-down decreasing cross sectional area in a direction towards the distal end which is fully hardened throughout its longitudinal length. A single coil, or two coils are carried by and secured to said core element near the distal end.
