Resonant Catheter Design: The wireless resonant circuit, consisting of a single loop copper coil connected to a tunable flexible printed circuit board capacitor (55–100 pF), is tuned to the Larmor frequency of 63.89 Mhz and embedded in distal tip of a polyether ether ketone (PEEK) fiber thread catheter. The catheter is then coated with a protective Pebax layer
