OG exemplary drawing
 
1. An omnidirectional magnetic resonance imaging (“MRI”) resonant marker, comprising:
a) a tunable capacitor comprising a first flexible circuit laminate; and
b) a conductor coil comprising a second flexible circuit laminate comprising:
a first trace portion operably coupled to the tunable capacitor, and
a second trace portion operably coupled to the first trace portion opposite from the tunable capacitor,
wherein the second flexible circuit laminate is configured to wrap around a medical device to form the conductor coil in which the first trace portion extends away from the tunable capacitor and the second trace portion extends back toward the tunable capacitor such that a distal end of the second trace portion operably couples to the tunable capacitor.
