    摘要: An apparatus includes an occlusion device operable to fit securely in an anatomical passageway within a head of a human. The occlusion device is configured to move unitarily with the head when the occlusion device is installed in the anatomical passageway. The occlusion device is further configured to prevent passage of fluid through the anatomical passageway when the occlusion device is installed in the anatomical passageway. A position sensor is fixedly integrated into the occlusion device. The position sensor generates signals indicating a position of the occlusion device in three-dimensional space, thereby indicating the position of the head in three-dimensional space. A connector communicatively coupled to the position sensor is operable to receive and transmit the signals generated by the position sensor.

    摘要: Some target anatomies within the ear, nose and/or throat of a patient may be difficult to access and treat. To provide a means of treating such target anatomies over time, drug delivery devices that are sized to be positioned within a naturally occurring or man-made anatomical cavity or passageway are preloaded with active agent(s). The drug delivery devices are affixed directly to, or in the vicinity of, a target anatomy. Once affixed, the drug delivery devices are configured to deliver active agent(s) at desired dosage(s) to the target anatomy through controlled elution of the active agent(s) as various structural features of the drug delivery devices are bio-eliminated.

    摘要: An apparatus includes a cannula assembly and a sensor assembly. The cannula assembly includes a proximal end, a distal end, and a first lumen extending from the proximal end to the distal end. The cannula is formed of a rigid material. The sensor assembly includes a sensor and a communication wire. The sensor is fixed to the cannula assembly. The communication wire is in electrical communication with the sensor. The communication wire extends along a length of the cannula assembly exterior to the first lumen.

    摘要: An apparatus such as a suction instrument includes a position sensor proximate to a distal tip of a malleable shaft. A sensor wire couples the position sensor to a processor of an image guided surgery system such that signals generated by the position sensor can be interpreted to determine the position of the surgical instrument. The malleable shaft includes a malleable outer shaft and a flexible inner tube. The flexible inner tube includes a primary lumen that can provide suction, fluid, or various deployable surgical tools, and an inner lumen that holds the sensor wire. Protected within the inner lumen, the sensor wire runs the length of the shaft and exits the inner lumen and passes through a slot in the outer shaft to reach the position sensor. A heat shrink cover wraps the distal tip, sealing the components together and providing an opening suitable for suction.

    摘要: A surgical navigation system includes an endoscope having a body, a shaft having a distal shaft end, an optical conduit, and a moveable optical element. The moveable optical element is configured to provide a field of view defining a line of sight, and is operable to capture an image within the field of view. The system further includes a drive mechanism operable to move the movable optical element to adjust a direction of the line of sight, a navigation sensor operable to generate a signal corresponding to a location of the distal shaft end within a patient, and a processor. The processor is operable to determine a location of the distal shaft end within the patient based on the signal, and command the drive mechanism to position the movable optical element so the line of sight is directed toward a selected point of interest within the patient.

    摘要: A guidewire includes a guidewire shaft and an inflatable element arranged at a distal end of the guidewire shaft. At least a portion of the guidewire shaft is formed of metal, and the guidewire shaft includes a lumen that fluidly communicates with an interior of the inflatable element. The inflatable element is operable to transition between a deflated state in which the inflatable element is configured to pass through an isthmus of a Eustachian tube (ET), and an inflated state in which the inflatable element is configured to dilate the ET.

    摘要: A surgical instrument includes an elongate body configured to be inserted through the nasal cavity of a patient, and a plurality of electrodes spaced circumferentially about an exterior of the elongate body. The electrodes may be arranged at a distal end of the elongate body, and are configured to deliver bipolar RF energy to tissue for sealing the tissue. The elongate body may be in the form of a shaft having a lumen configured to draw fluid proximally through the surgical instrument with suction.
