1. A controller for simultaneously tracking multiple sensors in a medical intervention, the controller comprising:
a circuit operatively in communication with a tracking system over one and only one channel, the circuit configured to:
receive, from a first passive ultrasound sensor of a first interventional medical device, a first signal with first sensor information indicative of a location of the first passive ultrasound sensor;
receive, from a second passive ultrasound sensor of a second interventional medical device, a second signal with second sensor information indicative of a location of the second passive ultrasound sensor;
combine the first signal and the second signal into a combined signal for transmission over the one and only one channel;
perform a signal modification with respect to at least one of the first signal and the second signal that enables identification of the first signal and the second signal in the combined signal; and
transmit the combined signal over the one and only one channel to a tracking system configured to track the first interventional medical device and the second interventional medical device, wherein the tracking device determines the location of the first passive ultrasound sensor and the location of the second passive ultrasound sensor from the combined signal based on the signal modification.
