1. A light emitting guidewire comprising:
a flexible integrated guidewire, comprising;
a hollow tube, having a proximal and a distal end;
a first conductive path disposed within the hollow tube from the proximal to the distal end comprising a first wire; and
a second conductive path disposed within the hollow tube from the proximal to the distal end and comprising a second wire;
a plurality of light sources disposed at the distal end of the tube; and
an external power supply energizing the plurality of light sources;
wherein the first and the second conductive paths are configured to electrically couple the plurality of light sources to the external power supply and supply illuminating power to the plurality of light sources, and
wherein at least one of the first and the second conductive paths comprises a crenellated configuration.
