Abstract: A flexible intravascular guidewire comprises a plurality of filaments braided together and drawn through a die to a reduced cross-sectional area of circular shape. Preferably, one or more of the filaments is coated with a radiopaque material prior to drawing it through the die. According to a preferred embodiment, each of the filaments is made from the same metallic material; alternatively, the filament material may differ, e.g., to provide flexibility and torsional stiffness characteristics which are unachievable in a metal monofilament, or in a multifilament wire of the same filament materials.
