Abstract (en)
[origin: WO0195794A1] A guidewire (10) compatible for use with magnetic resonance systems and/or x-ray fluoroscopy is made from non-metallic materials with a high specific electric impedance, preferably constructed primarily of polymers. An outer polymer tubular sheath (18) is provided that is sealed at a proximal end (24) and a distal end (26). One or more markers (16) may be provided in selected locations inside the polymer sheath (18). The markers (16) are magnetic resonance markers and/or radiopaque markers. The outer sheath (18) may be sheathed in a protective layer which is also non-metallic and tends to improve the physical characteristics of the guidewire.
