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 is used to manufacture a surgical guidewire that includes an outer coil assembly, a position sensor, a communication wire, an adhesive, a core wire, a hollow tube, and an atraumatic tip. The outer coil assembly has an outer coil that extends distally from a proximal coil retainer to a distal coil retainer. The position sensor is located distally within the outer coil assembly and is configured to be in communication with a processor via the communication wire. The core wire is between an outer coil proximal portion and the hollow tube. A distal end of the hollow tube is bonded to the atraumatic tip. The method includes affixing the atraumatic tip to the distal end of the hollow tube with the adhesive. The adhesive is constructed of instant glue.

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.

摘要： A system (11) includes a medical probe (36) for insertion into a cavity of an organ, which includes a position and direction sensor (60) and a camera (45), both operating in a sensor coordinate system (62). The system further includes a processor (44) configured to: receive, from an imaging system (21) operating in an image coordinate system (28), a three-dimensional image of the cavity including open space and tissue; receive, from the medical probe, signals indicating positions and respective directions of the medical probe inside the cavity; receive, from the camera, respective visualized locations inside the cavity; register the image coordinate system with the sensor coordinate system so as to identify one or more voxels in the image at the visualized locations, and when the identified voxels have density values in the received image that do not correspond to the open space, to update the density values of the identified voxels to correspond to the open space.

摘要： A system to dilate a stenotic region of an airway of a patient includes a stylet and a dilation catheter. The dilation catheter includes a catheter shaft and an inflatable balloon. The catheter shaft defines a shaft lumen and is configured to receive at least a portion of the stylet. The shaft lumen is axially aligned with a first longitudinal axis. The inflatable balloon is in fluid communication with an inflation lumen. The inflatable balloon is configured to transition between non-expanded and expanded configurations using the inflation lumen. The inflatable balloon has an outer perimeter configured to contact the stenotic region of the airway when in the expanded configuration. The inflatable balloon includes a pass-through lumen that is axially aligned with a second longitudinal axis that is laterally offset a distance from the first longitudinal axis. The pass-through lumen is disposed completely within the outer perimeter of the inflatable balloon.

摘要： A surgical system and method are used to position a guidewire within an anatomical passageway includes the guidewire, a dilator, a reference feature, and a marker. The guidewire has a guidewire body extending to a distal body end portion. The dilator is secured on the distal body end portion and configured to expand from a contracted state to an expanded state. The dilator in the contracted state is configured to pass through an isthmus of a Eustachian tube. The dilator in the expanded state is configured to dilate the Eustachian tube. The reference feature secured relative to the guidewire, and the marker is positioned on the guidewire a predetermined distance from the reference feature. Thereby, the marker is configured to indicate the predetermined distance to an operator for determining a depth of the reference feature in the anatomical passageway.

摘要： A medical device for the treatment of a sinus opening includes a handle, a grooming sheath, a rail, a guide wire, a balloon catheter and a balloon catheter movement mechanism. The handle has a proximal end, a distal end and a longitudinal axis along the length of the handle. The grooming sheath has a distal end and a proximal end with the proximal end of the grooming sheath being attached to the distal end of the handle. The rail has a distal end and a proximal end and disposed partially within the grooming sheath to define an annular lumen is between the rail and the grooming sheath. The guide wire operatively extends from the distal end of the rail and the balloon catheter is disposed at least partially in the handle and annular lumen. The balloon catheter movement mechanism operatively disposed on the handle and configured for advancement and retraction of the balloon catheter through both the handle and the annular lumen and along both the rail and guide wire by user operation of the balloon catheter movement mechanism. A method for treating a sinus opening includes inserting a medical device for the treatment of a sinus opening partially into a patient's anatomy and then positioning a guide wire operatively extending from a rail of a medical device into a sinus opening of the patient. The method further includes advancing a balloon catheter from an annular lumen of the medical device and along both the rail of the medical device and the guide wire. The method also includes treating the sinus opening via inflation of the balloon catheter. In the method, the annular lumen is between the rail and a grooming sheath of the medical device and the advancing is accomplished via user operation of a balloon catheter movement mechanism of the medical device.
