Patent Images
1. A guidewire assembly comprising:
- a guidewire having;
a proximal end;
a distal end;
a solid core wire extending between the proximal end and the distal end;
a plurality of electromagnetic microsensors having a hollow ferrite core, wherein the plurality of electromagnetic microsensors are spaced apart from each other and positioned on the solid core wire so that the solid core wire extends through the hollow ferrite core of the plurality of electromagnetic microsensors;
an outer member forming an outer covering of the guidewire; and
a flexible tip positioned at the distal end of the guidewire.
