Abstract: During surgery, debris being cleared from the target anatomy may inadvertently inhibit fluid communication between a suction instrument and a suction source. Therefore, it may be desirable to facilitate access to interior portions of the suction instrument and control of the amount of suction being provided through the suction instrument. The suction instrument can include an elongate cannula with a distal portion configured to be positioned within or adjacent to an anatomical passageway of a patient. The elongate cannula can define a suction lumen that can provide suction at the distal portion. A handle assembly can be associated with the elongate cannula and include a deformable grasping body defining a fluid communication chamber that can provide suction to the suction lumen. The deformable grasping body can elastically deform between relaxed and compressed states to alter the fluid communication between the fluid communication chamber and the suction lumen.

Abstract: Navigation sensors can indicate a real-time location of a surgical instrument within a patient. An adapter or other component that can be readily coupled with a surgical instrument and has one or more integral navigation sensors. The adapter can include an adapter body, an instrument coupling arm, and one or more navigation sensors. The adapter body extends between a proximal end and a distal end of the adapter. The instrument coupling arm is configured to non-removably engage a portion of the instrument. The one or more navigation sensors are configured generate signals indicating a position of at least a portion of the instrument in three-dimensional space and can be arranged in various configurations about the adapter body.

Abstract: An apparatus for use with an instrument includes a hub, a shaft assembly, and a navigation sensor.

The navigation sensor can be disposed proximate the open distal end of the shaft assembly. The navigation sensor can be configured to generate a signal indicating a portion of at least a portion of the shaft assembly in three-dimensional space.

Abstract: An apparatus includes a base, an actuator, and a clamp member. The actuator is pivotably coupled with the base. The clamp member is operable to selectively clamp a malleable guide rail relative to the base. The guide rail is configured to fit in an anatomical passageway in a head of a patient. The actuator is operable to pivot relative to the base to thereby bend the guide rail while the guide rail is clamped by the clamp member.

Abstract: An apparatus includes a handle, a guide member extending distally from the handle, and a dilation catheter slidably disposed relative to the guide member. The dilation catheter is operable to translate relative to the handle along a longitudinal range of motion from a proximal-most position to a distal-most position. The dilation catheter includes an expandable element configured to dilate a passageway within the head of a patient and a distal end. The dilation catheter actuator includes a rotary member operable to rotate relative to the handle to thereby drive translation of the dilation catheter along the longitudinal range of motion.

Abstract: A dilation catheter is slidably disposed relative to a first guide. A second guide is slidably disposed relative to the first guide and relative to the dilation catheter. The second guide includes an indicator element indicating a position of the distal end of the second guide in three-dimensional space. The second guide positions the indicator element at the distal end of the first guide and remains longitudinally stationary as the dilation catheter translates distally from a proximal position to an intermediate longitudinal position. The second guide translates concomitantly with the dilation catheter as the dilation catheter translates distally from the intermediate longitudinal position to a distal position. The indicator element is positioned with the distal end of the dilation catheter as the dilation catheter translates distally from the intermediate longitudinal position to a distal position.
