The present invention is for a guide wire with an improved flexible distal section with both a radiolucent coil and radiopaque coil. The guide wire comprising a core wire having a proximal end and a distal end, the proximal end of the core wire having a first diameter and the distal end having one or more reduced diameters, a radiolucent coil surrounding the reduced diameter of the core wire, the radiolucent coil having a proximal end and a distal end, the radiolucent coil having a length that is shorter than the reduced diameter of the core wire, the proximal end of the radiolucent coil being fixedly mounted to the proximal end of the reduced diameter of the core wire, a radiopaque coil surrounding the reduced diameter of the core wire, the radiopaque coil having a proximal end and a distal end, the radiopaque coil having a length that is shorter than the reduced diameter of the core wire such that the total length of the radiolucent coil and the radiopaque coil added together are approximately the same length as the reduced diameter of the core wire, the proximal end of the radiopaque coil being concentrically welded to the distal end of the radiolucent coil, the distal end of the radiopaque coil being welded to the distal end of the reduced diameter of the core wire forming a tip ball and a spring brace located distal of the welded connection between the radiolucent coil and the radiopaque coil, the spring brace attaching the radiopaque coil to the reduced diameter of the core wire.
