摘要： An apparatus includes a body, a shaft assembly, and a visualization assembly. The body includes first and second actuators. The shaft assembly extends distally from the body and includes a rigid proximal portion and a steerable distal portion. The steerable distal portion is positioned distally relative to the rigid proximal portion. The first actuator is operable to drive the steerable distal portion to deflect laterally relative to a longitudinal axis defined by the rigid proximal portion. The steerable distal portion is configured to fit within a nasal cavity of a patient. The visualization assembly is disposed within the shaft assembly. The visualization assembly includes a camera. The second actuator is operable to drive longitudinal translation of the visualization assembly relative to the shaft assembly.

摘要： An apparatus includes a shaft, a balloon, a tip member, and a heating feature. The tip member is distal to the balloon and has a larger outer diameter than the shaft. The heating feature is operable to ablate tissue of the Eustachian tube contacting the balloon in the expanded state. The heating feature may include an illuminating element and a photosensitive coating on the balloon. Alternatively, the heating feature may include a thermal heating element that heats the balloon inflation fluid and thereby heats the wall of the balloon. Another apparatus includes a shaft, a tip member, and an electrode assembly. The electrode assembly includes a plurality of electrodes positioned along the shaft near the distal end, proximal to the tip member. The electrodes are spaced apart from each other along a longitudinal axis and are operable to apply RF energy to tissue to thereby ablate the tissue.

摘要： A surgical instrument includes a sheath and an ablation catheter disposed within the sheath. The sheath is configured to be inserted into a cavity of a patient's head. The ablation catheter extends along a longitudinal axis and includes at least one expandable ablation member configured to selectively radially expand outwardly from a non-expanded state to an expanded state for selectively ablating tissue within the patient's head. The ablation catheter is selectively translatable relative to the sheath between a proximal retracted position and a distal extended position. In the retracted position, the at least one expandable ablation member is housed within the sheath to thereby prevent the at least one expandable ablation member from radially expanding outwardly. In the extended position, the at least one expandable ablation member is exposed from the sheath to thereby permit the at least one expandable ablation member to radially expand outwardly for contacting tissue.

摘要： 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.

摘要： An apparatus includes a body, an upright member, a frame, and a plurality of field generating elements. The body is configured to be positioned between a patient's back and a backrest of a chair. The upright member extends upwardly from the body. The frame has a curved configuration configured to partially surround a patient's head. The field generating elements are configured to generate an electromagnetic field around a patient's head partially surrounded by the frame.

摘要： Variations of integral navigation controls may be used in conjunction with a medical instrument to provide navigation functions for an image guided surgery (IGS) system that is in communication with the integral navigation controls. In some variations, a medical instrument with integrated navigation wheels allows movement of a cursor of the IGS system along the x and y axis by scrolling the wheel, or allows selection, zooming, or other controls by combined clicking and/or scrolling of wheels, and may be sterilized or discarded along with the device. In some other variations, a control overlay may be temporarily attached to the medical instrument to provide additional controls, such as buttons or a pointing stick, and then removed and sterilized or discarded after a procedure. In each variation, inputs may be communicated via wire or wirelessly to an IGS system to provide navigation of images during a surgical procedure.

摘要： An apparatus includes a shaft assembly and an electrode assembly at a distal end of the shaft assembly. The electrode assembly includes a first conductive segment extending along a first angular range at the distal end of the shaft assembly. The first conductive segment is operable to apply RF energy to tissue at a first polarity. The electrode assembly further includes a second conductive segment angularly spaced apart from the first conductive segment. The second conductive segment extends along a second angular range at the distal end of the shaft assembly. The second conductive segment is operable to apply RF energy to tissue at a second polarity such that the first and second conductive segments are operable to apply bipolar RF energy to tissue.

摘要： A dilation catheter includes a catheter shaft, an expandable element, and a navigation sensor. The catheter shaft has a proximal shaft portion defining a proximal shaft end, a distal shaft portion defining a distal shaft end, and a working lumen extending between the proximal and distal shaft ends. The expandable element is disposed on the distal shaft portion proximally of the distal shaft end, and is configured to expand to dilate an anatomical passageway of a patient. The navigation sensor is arranged at the distal shaft portion, and is configured to generate a signal corresponding to a location of the distal shaft portion within the patient. In various examples, the dilation catheter may further include a bulbous distal tip, and the navigation sensor may be arranged within the bulbous distal tip.
