Abstract
An instrument includes a handle assembly, a shaft, a dilation catheter, and a position sensor. The shaft extends distally from the handle assembly. The shaft includes a distal end that is configured to be introduced into an anatomical passageway within a head of a human. The dilation catheter includes an expandable dilator and is configured to advance distally relative to the shaft. The position sensor is configured to generate signals indicating a position of the position sensor within the head. The position sensor is configured to advance distally between at least first and second positions. The position sensor is disposed adjacent the distal end of the shaft in the first position, and is configured to be carried further distally by the dilation catheter to the second position. In the second position, the position sensor is separated a distance from the distal end of the shaft.
