Abstract
An apparatus includes a handle assembly, a guide tube, and a dilation catheter. The guide tube extends distally from the handle assembly. At least a distal portion of the guide tube is malleable. The dilation catheter is slidably positioned in the guide tube. The dilation catheter includes a distal end, a dilator, and a position sensor. The position sensor is configured to generate a signal indicating a position of the position sensor in three-dimensional space. The dilation catheter is configured to translate relative to the guide tube.
