Abstract:
1. A method for forming an intraluminal medical guidewire, comprising: providing a solid, cylindrical core having a distal core section with a distal end and a proximal end, the proximal end transitioning to a proximal core section; forming a distal coil by wrapping onto the distal core section a single strand of a first coil wire having a polygonal cross-sectional shape with a height and a width, wherein the polygonal cross-sectional shape rotates 360° about a longitudinal axis of the first coil wire and along a length of the first coil wire to create a continuous twist; wherein the first coil wire includes a plurality of turns forming a helix having a constant outside diameter; and anchoring the first coil wire to the distal core section.
