Abstract
A system includes a dilation catheter and a guide member. The dilation catheter includes a proximal end, a distal end, a dilator, a navigation sensor, and a force sensor. The dilator is positioned proximal to the distal end and is configured to transition between a non-dilated configuration and a dilated configuration. The navigation sensor is positioned distal to the dilator and is configured to cooperate with a guidance system and thereby provide signals indicating a position of the dilation catheter in three-dimensional space. The force sensor is positioned distal to the dilator and is configured to provide signals indicating a force encountered by the force sensor. The dilation catheter is configured to slide relative to the guide member. A distal portion of the guide member is sized and configured to fit in a nasal cavity of a patient.
