A dilation catheter of a medical instrument can translate longitudinally relative to a guide of the medical instrument to position the guide relative to a target anatomical passageway before entering the passageway. The medical instrument can have a handle assembly, a guide member extending distally relative to the handle assembly, a dilation catheter slidably disposed relative to the guide member, and a dilation catheter actuation assembly. Optionally, the dilation catheter can translate relative to the handle assembly along a longitudinal axis. The dilation catheter can include an expandable element configured to dilate the passageway. The dilation catheter can include a first rotary member that rotates relative to the handle assembly about a first rotation axis that is substantially parallel to the longitudinal axis to thereby drive translation of the dilation catheter along the longitudinal axis.
A dilation apparatus can include a body, a guide member, a dilation catheter, and a dilation catheter actuation assembly. The dilation catheter is slidably disposed relative to the guide member between a proximal position and a distal position. The dilation catheter actuation assembly is configured to drive the dilation catheter relative to the guide member between the proximal position and the distal position. The dilation catheter actuation assembly includes a first cable and a first pulley. The first cable includes an anchor attached to the proximal shaft of the dilation catheter. The first pulley is rotatably coupled to the body via a first axle. The first pulley is configured to rotate relative to the body via the first axle in a first angular direction to simultaneously gather a portion of the first cable and actuate the dilation catheter toward the distal position.
A patient tracker apparatus can include a position sensor, an outer member, and an inner member. The outer member can have a tubular portion with a sidewall and define a longitudinal axis. The tubular portion can include an opening through the sidewall and be configured to secure to a bone of a patient.

DILATION INSTRUMENT WITH TRANSLATABLE AND MALLEABLE SLEEVE
A method includes positioning a dilation catheter within a malleable sleeve such that a dilator of the dilation catheter is housed within the malleable sleeve. The method also includes inserting a bent distal portion of the malleable sleeve into an ear, nose, or throat of a patient. The method also includes advancing the bent distal portion of the malleable sleeve toward a targeted anatomical passageway of the patient until the dilator is disposed within the targeted anatomical passageway. The method further includes, while the dilator is disposed within the targeted anatomical passageway, retracting the malleable sleeve relative to the dilator to thereby expose the dilator within the targeted anatomical passageway. The method further includes transitioning the dilator from a non-expanded state to an expanded state within the targeted anatomical passageway to thereby dilate the targeted anatomical passageway.
A dilation instrument can be configured to provide real-time tracking of components of the instrument during a surgical procedure, such as by providing real-time tracking of respective positions of the components during the procedure. The dilation instrument can include a body, a shaft assembly, a guide element, a working element, and a movement tracking feature. The guide element can translate relative to the body and have a position sensor that can provide a signal indicating a position of the guide element in three-dimensional space. The working element can translate relative to the body and the guide element. The movement tracking feature can generate a signal indicating movement of the working element relative to the body and/or the guide element.

SUCTION INSTRUMENT WITH DEFORMABLE MULTI-PIECE GRIP ASSEMBLY
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.

A virtual endoscopic view shows a surgical area and surrounding anatomy and may also show a position of a surgical instrument in use during a surgical procedure, allowing a surgeon to virtually view the surgical area when direct viewing or actual endoscopic views are incomplete, obstructed, or otherwise unavailable or undesirable. In order to render the endoscopic view, an IGS navigation system may be configured with an observer point and an observer orientation within 3-D space based upon user inputs. A user interface for defining these points allows a user to view a virtual endoscopic preview in real-time while providing inputs, thus improving the likelihood that the resulting virtual endoscopic view is as desired by the user; and reducing time spent redefining and reconfiguring the virtual endoscopic view. The virtual endoscopic preview may provide combinations of static and dynamic images to illustrate the spatial relationship of the provided inputs.

A virtual endoscopic view shows a surgical area and surrounding anatomy and may also show a position of a surgical instrument in use during a surgical procedure, allowing a surgeon to virtually view the surgical area when direct viewing or actual endoscopic views are incomplete, obstructed, or otherwise unavailable or undesirable. In order to render the endoscopic view, an IGS navigation system may be configured with an observer point and an observer orientation within 3-D space based upon user inputs. A user interface for defining these points allows a user to view a virtual endoscopic preview in real-time while providing inputs, thus improving the likelihood that the resulting virtual endoscopic view is as desired by the user; and reducing time spent redefining and reconfiguring the virtual endoscopic view. The virtual endoscopic preview may provide combinations of static and dynamic images to illustrate the spatial relationship of the provided inputs.

CUSTOMIZED PATIENT TRACKER FOR IMAGE GUIDED SURGERY
An apparatus includes a mounting portion and a sensor portion. The mounting portion is configured to fit over a nose of a preselected patient. The mounting portion includes a base and a pair of rigid nose pads fixedly coupled to the base. Each nose pad of the pair of nose pads includes a respective nose-gripping surface. The nose-gripping surfaces of the nose pads are configured to engage the nose of the preselected patient at respective predetermined locations along the nose. Each nose-gripping surface is sized and shaped to complement a corresponding unique structural feature of the nose of the preselected patient at the predetermined location. A sensor portion is fixedly attached to the mounting portion. The sensor portion includes a first sensor configured to generate a first signal corresponding to a position of the first sensor in three- dimensional space.
