Abstract: A magnetically-tracked catheter system having a catheter and a magnetic beacon. The catheter has a proximal end and a distal end. The catheter includes a first magnetic sensor disposed at (i.e., near) the distal end. The magnetic beacon is configured to be disposed external to an individual and in a target zone. An operator interface is in electronic communication with the first magnetic sensor. The catheter may further include a guide lumen (and/or other lumen or lumens) extending between the proximal end and the distal end and the configured for use with a guidewire. The catheter may include an occlusion member configured to occlude a vessel or other passage of an individual (e.g, respiratory tract, gastrointestinal tract, etc.).
