Abstract
A dilation catheter device and system for dilating an opening in a paranasal sinus and/or other passageways within the ear, nose or throat is disclosed. A dilation catheter device and system is constructed in a manner that facilitates ease of use by the operator and, in at least some cases, allows the dilation procedure to be performed by a single operator. Additionally, the dilation catheter device and system may be useable in conjunction with an endoscope and/or a fluoroscope to provide for easy manipulation and positioning of the devices and real time visualization of the entire procedure or selected portions thereof. In some embodiments, shaft markers are disposed on a shaft of the dilation catheter and have a light color to contrast with a dark color of the dilation catheter shaft. The high contrast between the markers and catheter shaft allows for easy viewing of the markers in low light and operation conditions.
