Abstract
Catheter shafts (such as guide catheter or dilation catheter shafts) disclosed herein can include a rigid proximal portion, a deflectable distal portion located distally from the proximal portion, and a pull wire extending from the deflectable distal portion along the proximal portion. The pull wire can drive the deflectable distal portion between a straight configuration and a bent configuration, which makes the catheter system adaptable for use with both pediatric and adult patients. Specifically, because the pull wire facilitates changing a bend angle of the deflectable distal portion of the catheter shaft, the catheter can fit in a wide variety of differently sized nasal cavities and Eustachian Tubes. Optionally, a visualizing distal tip can be positioned distally from the deflectable distal portion of the catheter shaft and include a distally facing camera that can be used to confirm that the deflectable distal portion is properly positioned in the patient.
