Abstract: A stylet includes a handle assembly with an indicator display and a stiff wire assembly extending distally from the handle assembly having a non-imaging ultrasonic device on a distal end. The stylet includes a circuit assembly having one or more of a pulser, a transmit/receive chip, a bandpass filter, a differential amplifier, an ADC, and an MCU, operable to control the operation of the ultrasonic device and to receive and analyze data from the ultrasonic device to facilitate implantation of a device such as a catheter.
