Claim:
1. An electrode for use on a medical device comprising: a main body of electrically conductive material extending along an axis and comprising a proximal end, a distal end, and a wall disposed about and defining a lumen extending along said axis; an electrical conductor having a first end coupled to said body and a second end configured for connection to an energy source, wherein said conductor comprises electrically conductive wire having an insulated portion and an uninsulated portion, the uninsulated portion formed in a plurality of turns, wherein said uninsulated portion of said electrically conductive wire is disposed in said lumen and wherein at least part of said uninsulated portion of said electrically conductive wire is configured to engage said wall; and a magnetic resonance imaging (MRI) tracking coil comprising electrically insulated wire that is wound in a plurality of turns that each extend circumferentially around said axis, wherein said MRI tracking coil further comprises an opening configured to receive a portion of the medical device that extends along said axis, wherein said MRI tracking coil is one of: embedded directly within said wall; and disposed directly within said lumen, further wherein said MRI tracking coil is electrically coupled with two wires that are configured to transmit an induced electromotive force to an MRI system when the MRI system is activated, said induced electromotive force being indicative of a location of said MRI tracking coil.
