Abstract
A system of medical devices includes a first medical device, a second medical device, an RLC circuit, a processor, and an output device. The first medical device includes an elongate member having a lumen. The second medical device includes a needle advanceable through the lumen. The RLC circuit includes an excitation voltage source, a resistor, a capacitor, an inductor, and an output voltage sensor. The inductor includes a coil that is supported by the first medical device and wound around the lumen. As the needle is advanced through the lumen, an output voltage of the RLC circuit is an indicator of a longitudinal position of the needle with respect to the elongate member. The voltage sensor is configured to sense the output voltage, and the processor and output device are configured to generate an output that is an indicator of the longitudinal position of the needle.
