摘要： Apparatus, including a patient tracker, attached to a subject, having magnetic field sensors and optical landmarks with known spatial relationships to each other. A camera acquires a 3D optical image, in a first frame of reference (FOR), of the subject's face. A magnetic radiator assembly generates magnetic fields at the subject's head, thereby defining a second FOR. A processor: processes field sensor signals to acquire location coordinates of the sensors in the second FOR; segments a tomographic image of the subject, having a third FOR, to identify the subject's face in the third FOR; computes a first transformation between the third and first FORs to map the tomographic face image to the 3D optical image; maps the optical landmarks to the third FOR; maps the respective location coordinates of the sensors to the first FOR; and computes a second transformation between the second FOR and the third FOR.

摘要： An apparatus includes an elongate shaft and a position sensor. The elongate shaft defines a longitudinal axis. The elongate shaft includes a distal end, an opening, and a lumen. The position sensor is laterally offset from the longitudinal axis. The first position sensor is fixedly secured relative to the elongate shaft at a known distance from the opening. The first position sensor is configured to generate signals indicating a position of the elongate shaft in three- dimensional space.

摘要： A surgical instrument (10) for cutting a tissue includes a shaft (28), a cutting member (30), and an alignment system (114, 214, 314, 414). The shaft (28) extends along a longitudinal axis (42) and includes a shaft opening (50). The cutting member (30) is disposed within the shaft lumen (32) to cyclically move from an open state to a closed state. The cutting member (30) includes a sidewall (62), a cutting window (54), and a suction lumen (60). The cutting window opening (54) in the open state aligns with the shaft opening (50) such that the cutting window opening (54) and the shaft opening (50) are in fluid communication. The sidewall (62) in the closed state aligns with the shaft opening (50) such that the sidewall (62) blocks fluid communication to the shaft opening (50) for inhibiting suctioning the tissue therethrough. The alignment system (114, 214, 314, 414) urges movement of the cutting member (30) moving the open state toward the closed state such that the cutting member (30) stops in the closed state.

摘要： A surgical navigation system (100) includes an endoscope (10) having a body (12), a shaft (14) having a distal shaft end (16), an optical conduit (28), and a moveable optical element (32). 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 (70) operable to move the movable optical element to adjust a direction of the line of sight, a navigation sensor (40, 42) operable to generate a signal corresponding to a location of the distal shaft end within a patient, and a processor (108). 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： An apparatus includes a proximal coil, a distal potion, a navigation sensor, and a communication wire. The proximal coil is formed by a wire wrapped in a helical configuration. The proximal coil is flexible. The distal portion is positioned at a distal end of the proximal coil. The distal portion is non-extensible. The distal portion may be formed by a rigid tube. The distal portion may alternatively be formed by a soldered region of the proximal coil. The navigation sensor is located within the distal portion. The navigation sensor is configured to generate signals in response to movement within an electromagnetic field. The communication wire is in electrical communication with the navigation sensor such that the communication wire is configured to communicate signals from the navigation sensor.

摘要： 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.

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 visualization system may be implemented with an image guided surgery navigation system for use during ENT procedures. Correlated datasets such as surgical paths and pre-operative image slices may be correlated with the coordinate system of the navigation system for reference during a procedure. A surgeon may wear a head mounted display ("HMD") having a transparent screen through which the patient anatomy may be viewed. The orientation and distance of the head mounted display relative to the patient anatomy may be determined using magnetic position tracking, image analysis of images captured by a camera of the HMD, or both. Correlated datasets may then be transformed based on the relative distance and orientation and may be displayed via the transparent screen to overlay directly viewed patient anatomy, Some implementations may include optical fiducials integrated with a patient tracking assembly to aid in tracking the patient and determining perspective of the HMD.

摘要： A surgical instrument and related method includes an instrument body, a guide shaft distally projecting from the instrument body, and a first surgical tool. The guide shaft has a guide sidewall, a guide lumen, and a clearance opening radially extending through the guide sidewall in communication with the guide lumen. The first surgical tool has an elongate body and a distal head configured to deflect relative to the elongate body from a first position to a second position. The distal head in the first position is positioned within the guide lumen along the central axis. The distal head in the second position is deflected from the central axis and extends at least partially through the clearance opening thereby vacating at least a portion of the guide lumen for introducing a second surgical tool through the guide lumen.
