Abstract
A suction instrument includes a proximal end, a distal end configured to be positioned within or adjacent to an anatomical passageway of a patient, and a suction lumen extending between the proximal and distal ends. The suction lumen is configured to provide suction at the distal end. A navigation sensor is disposed along a portion of the suction lumen and is operable to generate an electrical signal corresponding to a location of the portion within the patient. A coupling feature is disposed at the proximal end and is configured to releasably couple the proximal end with a body.
