The present disclosure provides apparatuses and methods for navigating a medical device into the body of a patient during an intracoronary or other medical procedure. In many embodiments, the present disclosure includes the use of a guidewire managing assembly that may be used in combination with a guidewire that includes a medical positioning system sensor. This guidewire managing assembly and sensor enabled guidewire are used in combination with a medical positioning system to determine the position of a medical device, such as a catheter or catheter sheath, and specifically the tip of the catheter or catheter sheath, that is threaded over the guidewire during a procedure. The present disclosure further relates to methods of tracking a medical device, such as a catheter tip, inside the body of a subject during a procedure.
