Abstract
Guidewire with an improved distal end. A guidewire with an improved distal end may include a core wire, a solder tip disposed at a distal end of the core wire, a radiopaque inner coil coupled to the distal end of the core wire, an outer coil disposed along the length of the core wire, and a distal hub coupled to the core wire and disposed proximate a distal end of the inner coil.
