Abstract
The present invention is for a guide wire comprising a core wire with a first diameter and the distal end having at least one section having a second, lesser diameter and a radiolucent coil surrounding the distal end at the second core wire diameter with a radiopaque wire located at the distal end within the radiolucent coil and a means for securing the radiopaque wire to the core wire. Another embodiment of the present invention is a guide wire comprising a core wire having a radiolucent portion and a radiopaque portion, the radiopaque portion being distal of the radiolucent portion and contiguous with the radiolucent portion, the proximal end of the core wire having a first diameter and the distal end having at least one step down diameter section, a radiolucent coil surrounding the step down diameter section of the core wire, the proximal end of the radiolucent coil being fixedly mounted to the proximal end of the step down diameter section of the core wire, and a tip ball fixedly attached to the distal end of the core wire and to the distal end of the radiolucent coil.
