               1. A medical device comprising: 
            an elongate member having a proximal portion defining a proximal end, a distal portion defining a distal end, a sidewall extending longitudinally between the proximal end and the distal end and radially between an inner surface and an outer surface, and a lumen defined by the inner surface and extending longitudinally through the elongate member from the proximal end to the distal end; 
                an inductor comprising a coil embedded in the sidewall and wound around the lumen; 
                an excitation voltage source; 
                a resistor; 
                a capacitor; and 
                an output voltage sensor; 
                wherein the coil is electrically connectable to the excitation voltage source, the resistor, the capacitor, and the output voltage sensor to form an RLC circuit.
