摘要： A system effectively narrows a patulous Eustachian tube (ET) of a patient with a guide catheter, instrument, and insert. The guide catheter includes a shaft, a lumen and a distal end configured to provide access the ET when the guide catheter is inserted into a head of the patient. The instrument comprises a shaft. The insert comprises a body configured to radially expand and retract between a non-expanded state and an expanded state. The insert is sized and shaped to be received within the first lumen when in the non-expanded state and is operable to expand to the expanded state to substantially reduce an effective diameter of the ET.

摘要： A method of treating a patulous Eustachian tube includes forming a first pocket in a wall of a nasopharynx region proximate to a pharyngeal ostium, inserting a resiliently biased implant within the first pocket, and allowing the resiliently biased implant to expand within the first pocket to thereby urge the Eustachian tube towards a closed state. The wire implant may include a resilient stent or other resilient wire structure. In some versions, a deployment device having a balloon is used to deploy a malleable implant. This deployment device has a malleable implant disposed around the balloon, which is disposed around a guide catheter. The balloon is inflated and expands the malleable implant. The malleable implant retains the expanded shape and urges the Eustachian tube toward a closed state.

摘要： A surgical instrument includes an elongate shaft having a proximal shaft portion and a malleable distal shaft portion. The elongate shaft is configured to be secured to a supporting surgical instrument. An ablation head is coupled to the malleable distal shaft portion and includes at least one electrode operable to deliver RF energy to tissue for ablating the tissue. The ablation head is sized to fit within the nasal cavity of a patient with a distal end of the supporting surgical instrument. The proximal shaft portion is configured to operatively couple with an RF energy source operable to energize the at least one electrode with RF energy. The malleable distal shaft portion is configured to bend relative to a longitudinal shaft axis defined by the proximal shaft portion for selectively orienting the ablation head relative to the longitudinal shaft axis.

摘要： 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.
