摘要：
An apparatus (300) includes an outer coil (302), a navigation coil (310), and a distal tip member (304). The outer coil defines an interior region bounded by inner diameter. The navigation coil is positioned distal to the distal end of the outer coil. The navigation coil is configured to generate a signal in response to movement of the navigation coil within an electromagnetic field. The distal tip member is positioned distal to the navigation coil, such that the navigation coil is longitudinally interposed between the distal tip member and the distal end of the outer coil. The apparatus may be used in combination with a navigation system to provide navigation of paranasal sinus cavities and other structures within a patient.
