ABSTRACT:
A flexible guidewire having a radiopaque marker at its distal end. The marker is defined by a platinum band attached to a reduced diameter portion of a guidewire core wire. A flexible spring overlies the radiopaque marker bank. The spring is constructed of stainless steel. A weld band is formed at the distal end of the core wire and is fused to the distal end of the marker band to thereby cause these elements to be fused into a single unitary structure.
