  • Publication number: 20230355264
    Abstract: A surgical instrument for cutting a tissue and related methods includes a shaft, a cutting member, and an axial adjustment coupling. The shaft and the cutting member are configured to articulate from a first configuration toward a second configuration and respectively have distal and proximal shaft ends distal and proximal member ends. The cutting member is disposed within the shaft and configured to cyclically move relative to the shaft. The axial adjustment coupling is configured to longitudinally move the proximal member end relative to the proximal shaft end while articulating the shaft and the cutting member from the first configuration toward the second configuration. Thereby, the axial adjustment coupling inhibits movement of the distal member end relative to the distal shaft end for maintaining alignment between a shaft window opening in the shaft and a cutting window opening in the cutting member.

  • Patent number: 11744646
    Abstract: Tools used within a surgical area may be equipped with sensors that allow them to be tracked within the magnetic field of an image guided surgery (IGS) system. The IGS system may be configured to detect various movement patterns of the tools, which may be mapped to and associated with corresponding actions or inputs to the IGS system. In one example, a registration probe may be moved along the x-axis and y-axis, with detected movements identified and received by the IGS system as movements of a mouse cursor on a display of the IGS system. In another example, the registration probe may be moved in a circular pattern, or quickly moved along any of the x-axis, y-axis, or z-axis, with each being configured to cause the IGS system to zoom a display, change a view, record video, or other actions.

  • Patent number: 11576662
    Abstract: 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.

  • Publication number: 20230021788
    Abstract: 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.

  • Publication number: 20220313353
    Abstract: A surgical instrument includes a sheath and an energy catheter. The sheath is configured to be inserted into a nasal cavity of a patient's head. The energy catheter includes a shaft and an end effector. The end effector is configured to selectively expand radially outwardly. The end effector includes an energy member that includes a flexible wire and electrodes disposed along the wire. The energy catheter is selectively translatable relative to the sheath. In a proximal position, the end effector is housed coaxially within the sheath to thereby prevent the end effector from radially expanding. In a distal position, the end effector is exposed from the sheath to thereby permit the end effector to expand for contacting tissue in the nasal cavity of the patient's head. When the end effector is in the expanded state, the end effector has a width and a length greater than the width.

  • Patent number: 11419685
    Abstract: An array of sensors may be used to perform touchless registration of landmarks of a patient's face before an ENT procedure in order to associate those landmarks with pre-operative images in three-dimensional space, which is required for image guided surgery features such as navigation. Touchless or light-touch registration may improve accuracy by avoiding the need for substantial pressing against a patient's skin, which may deform and thereby introduce erroneous registration data. A sensor may also be implemented in forms other than an array such as handheld probe having a single sensor as opposed to an array.
