Abstract

A dilation catheter includes a catheter shaft, an expandable element, and a navigation sensor. The catheter shaft has a proximal shaft portion defining a proximal shaft end, a distal shaft portion defining a distal shaft end, and a working lumen extending between the proximal and distal shaft ends. The expandable element is disposed on the distal shaft portion proximally of the distal shaft end, and is configured to expand to dilate an anatomical passageway of a patient. The navigation sensor is arranged at the distal shaft portion, and is configured to generate a signal corresponding to a location of the distal shaft portion within the patient. In various examples, the dilation catheter may further include a bulbous distal tip, and the navigation sensor may be arranged within the bulbous distal tip.
