Abstract
This invention is a multipolar or multi-conductor guidewire which can be navigated or steered through the vasculature from outside a patient's body to perform a medical procedure within the patient's vasculature. In one embodiment, a guidewire of this invention has at least 4, preferably at least 6, to as many as 10 or more distal-to-proximal conductive pathways, which are substantially longitudinally parallel to each other running linearly along substantially the majority if not the entire length of the guidewire body, preferably in a printed circuit format. In a further practice, the conductive pathways helically wound around the guidewire body.
Claims11
A multi-conductor guidewire comprising:
- an elongate core solid wire having a proximal end and a distal end and defining a core wire surface;
- the core wire having disposed on its surface so as to provide multiple conductors between the core wire distal end and its proximal end;
- the multiple conductors comprising an electrically conductive pathway disposed upon a flexible, insulative backing member, the backing member being adhered to the core wire surface.
