1. A floppy guide wire comprising:
- a flexible elongate element formed of a metallic material portion, at least one tapered intermediate portion and a flattened distal portion having the distal extremity thereof unsecured;
a coil generally concentric with the flexible elongate element formed of a metallic material extending over at least a substantial portion of the proximal portion, the tapered portion, the flattened distal portion, and beyond the unsecured extremity of the distal portion, said coil being secured to said elongate element at an intermediate point along the length thereof and having a rounded metallic protrusion carried by the distal extremity of the coil; and
a safety wire disposed within the coil which is secured at the distal extremity thereof to the protrusion and at least one location along the length thereof to the flexible elongate element proximally spaced from the flattened distal portion thereof and distally spaced from the proximal extremity of the coil.
