A guidewire (10) having a proximal section (12), a distal section (14), and a transition section (16) is disclosed. The proximal section may be formed of a relatively stiff, inelastic material, whereas the distal section may be form ed of a relatively flexible, elastic material having superelastic properties. A coupling member may be placed adajcent to the transition section to secure t he proximal and distal sections together. An intravascular device such as an embolic protechon filter (46) is placed on the guidewire.
