Abstract
A guide wire is disclosed which has a radiopaque distal lip and three or nor discrete highly radiopaque sections separated by relatively non-radiopaque sections. The highly radiopaque sections may be formed of coils and may have a width greater than their diameter. A method of marking the position of an intravascular anatomical feature (e.g., a stenosis) using the guide wire is also disclosed.
