Abstract:
1. A method of making a wire guide, wherein the wire guide includes a mandrel positioned within a helically wound coil, and first and second safety wires positioned within the helically wound coil and having proximal ends attached to the mandrel and distal ends attached to a distal end of the helically wound coil, the method comprising the steps of: attaching the proximal ends of the first and second safety wires to opposite sides of the mandrel such that substantially flat contact surfaces or substantially concave contact surfaces of the first and second safety wires face a distal tip of the mandrel; inserting the mandrel and the first and second safety wires into the helically wound coil through a proximal end of the helically wound coil such that the mandrel terminates before the distal end of the helically wound coil; and welding the distal ends of the first and second safety wires to the distal end of the helically wound coil.
