Abstract
A method of positioning a catheter in a blood vessel. The method includes ultrasonically imaging the blood vessel using an ultrasound probe to generate an ultrasound image, communicating the ultrasound image to a console, and displaying the ultrasound image on the console. The method further includes coupling a stylet to the catheter, the stylet including a stylet control module including a timer circuit, and a coil assembly connected to the stylet control module. The method further includes introducing and advancing the catheter and the coil assembly in the blood vessel, sending an electric pulse signal from the timer circuit to the coil assembly at a pulse signal frequency, emitting an electromagnetic field from the coil assembly, and detecting the electromagnetic field by an external sensor. The method may further include synchronizing the pulse signal frequency, and determining a position of the coil assembly with respect to the external sensor.
