Abstract
A guidewire, consisting of a hollow tube, containing a longitudinal lumen and having a spiral channel cut into the tube, and having a distal end. The guidewire has an elongate flexible core positioned within the longitudinal lumen. The guidewire also has a conductive coil, wound around the core at a location within the lumen in proximity to the distal end, that is coupled to output a signal in response to a magnetic field applied to the guidewire.

A method, comprising:
- cutting a spiral channel in a hollow tube containing a longitudinal lumen, the hollow tube having a distal end;
- winding a conductive coil, coupled to output a signal in response to a magnetic field applied to the coil, around an elongate flexible core;
- and
- subsequent to the winding, sliding the conductive coil and the elongate flexible core within the longitudinal lumen so as to position the conductive coil in proximity to the distal end.
