First Claim
1. An implantable medical device, comprising:
- a stent;
a substrate surrounding a portion of said stent; and
a plurality of conductive traces formed on said substrate;
said plurality of conductive traces forming a plurality of loops to create a single spiraling coil, adjacent loops of said single spiraling coil having a non-conductive material therebetween;
said single spiraling coil forming an inductive coil;
said adjacent loops of said single spiraling coil having a non-conductive material therebetween forming a capacitor;
said inductive coil and said capacitor being tuned to a frequency associated with magnetic resonance imaging.

Abstract
A medical device enables effective magnetic resonance imaging inside a lumen of a medical device. The medical device includes a plurality of conductive traces formed on a substrate. The conductive traces form an inductive-capacitance circuit or a resistive-inductive-capacitance circuit. The inductive-capacitance circuit or resistive-inductive-capacitance circuit is tuned to a frequency associated with magnetic resonance imaging, an operating frequency associated with a magnetic resonance imaging scanner, a harmonic of an operating frequency associated with a magnetic resonance imaging scanner, or a sub-harmonic of an operating frequency associated with a magnetic resonance imaging scanner.
