Abstract
An apparatus and method for a thin, flexible catheter guide wire having portions of uniform and tapering diameters, a helical coil of a first radiopacity encasing or covering the distal end of the wire, and at least one additional wire cover of a lubricous material which is formed to be radiopaque but which has a radiopacity different than that of the helical coil. This improved device enables the use of an improved method of placement with the use of fluoroscopy to steer and locate the guide wire, and thus the catheter ultimately placed over the guide wire, at a precise situs within the body.
