A patient tracking device for insertion into an oral cavity includes a sensor housing comprising a first surface shaped to correspond to a pallet within the oral cavity. At least a portion of the first surface affixes the sensor housing to the oral cavity. An electromagnetic sensor is coupled to the sensor housing.

A surgical instrument assembly includes a surgical instrument having an instrument body, an elongate member with a distal end configured to be inserted into an anatomical passageway of a patient, a sensor operable to generate a signal corresponding to a location of the elongate member, and a first electrical connector electrically coupled with the sensor. The assembly further includes a cable assembly having a cable that communicates with a processor, and a coupling that releasably couples with the instrument body. The coupling includes a coupling body having first and second lateral sides that extend parallel to one another and are configured to extend parallel to a side of the instrument body when the coupling is coupled with the instrument body. The coupling includes a second electrical connector that electrically couples with the first electrical connector to transmit the signal from the sensor proximally through the cable and toward the processor.

A positioning system includes a group of positioning devices including a first device comprising a first positioning source associated with a first positioning modality, the first positioning source being configured to view a first field, a second device comprising a second positioning source associated with a second positioning modality that is of a different type than the first positioning modality, the second positioning source being configured to view a second field, a third device comprising one or more first markers detectable within the first field using the first positioning modality, and a fourth device comprising one or more second markers detectable within the second field using the second positioning modality. A linking structure physically links two of the group of positioning devices to one another in a fixed, rigid relative position and orientation.

The present disclosure relates to systems, devices, and methods for augmenting a two-dimensional image with three-dimensional pose information of instruments shown in the two-dimensional image.

Embodiments are directed to a medical robot system including a robot coupled to an end-effectuator element with the robot configured to control movement and positioning of the end-effectuator in relation to the patient. One embodiment is a method for removing bone with a robot system comprising: taking a two-dimensional slice through a computed tomography scan volume of target anatomy; placing a perimeter on a pathway to the target anatomy; and controlling a drill assembly with the robot system to remove bone along the pathway in the intersection of the perimeter and the two-dimensional slice.

The present disclosure describes a device that can be implanted into the left atrial appendage for occlusion. The device can prevent or reduce thrombus formation in this anatomic region for patients with atrial fibrillation. This device includes a patient-specific inflatable device that represents a patient's anatomy or morphological class. The inflatable device can be designed by imaging (e.g., computed tomography, magnetic resonance imaging) the patient's anatomy. Through a catheter (or surgically), the inflatable device can be filled with an inflation fluid to occlude the appendage in a patient-specific fashion.

A method for localizing a nodule of a patient includes inserting a delivery tool into tissue of a patient, such as lung tissue, releasing the magnetic fiducial into or adjacent a nodule from the delivery tool, and locating the magnetic fiducial with a localization tool.

A virtual model a planned instrument attachment can be provided to ensure correct selection of a physical instrument attachment. An XR headset controller can generate a shape and a pose of the virtual model of the planned instrument attachment based on predetermined information associated with the planned instrument attachment and based on a pose of an instrument relative to the XR headset. An XR headset can display the virtual model on a see-through display screen of the XR headset that is configured to allow at least a portion of a real-world scene to pass therethrough.

Embodiments include methods of identifying a personalized cardiovascular device based on patient-specific geometrical information, the method comprising acquiring a geometric model of at least a portion of a patient's vascular system; obtaining one or more geometric quantities of one or more blood vessels of the geometric model of the patient's vascular system; determining the presence or absence of a pathology characteristic at a location in the geometric model of the patient's vascular system; generating an objective function defined by a plurality of device variables and a plurality of hemodynamic and solid mechanics characteristics; and optimizing the objective function using computational fluid dynamics and structural mechanics analysis to identify a plurality of device variables that result in desired hemodynamic and solid mechanics characteristics.

A system and method for providing enhanced information to a surgeon is described. A three-dimensional reconstruction of a patient's anatomical structure selected for surgery and a representation of a surgical treatment apparatus are rendered on a display device. At least one attachment metric for a proposed attachment between the surgical treatment apparatus and the patient's anatomical structure is calculated using the three-dimensional position of the surgical treatment apparatus relative to the patient's anatomical structure. And, an indication of the attachment metric is rendered on the display device.
