    Abstract: This disclosure relates generally to systems and methods for localizing a device relative to an instrument. A sensor of the instrument can be monitored for a change in signaling during a first transition of the device relative to the instrument. The sensor can further be monitored for another change in signaling provided by the sensor of the instrument in response to a second transition of the device relative to the instrument. A transition distance difference can be determined between the first transition and the second transition. A location of the device relative to the instrument can be determined based on a location of the instrument and the transition difference distance.

    Abstract: System and methods are disclosed to facilitate intra-operative procedures and planning. A method can include storing tracking data in memory, the tracking data being generated by a tracking system to represent a location of an object in a tracking coordinate system of the tracking system. The method can also include storing a patient-specific implicit model in memory, the patient-specific implicit model being generated based on image data acquired for the patient to define geometry of an anatomical structure of the patient. The method can also include registering the tracking data and the patient-specific implicit model in a common three-dimensional coordinate system. The method can also include generating an output visualization representing a location of the object relative to the geometry of the anatomical structure of the patient in the common coordinate system.

    Abstract: An example system includes a distortion reference sensor (DRS) device attachable to a surface adjacent a region of interest within the patient. The DRS device includes at least two sensor coils arranged at a predetermined angle relative to each other and at a predetermined spatial position in a three-dimensional space relative to each other. The system also includes a computing device to determine a sensed angle and a sensed spatial position of the at least two sensor coils in the three-dimensional coordinate system in response to application of an electromagnetic field. Electromagnetic field distortion is indicated based on a difference between the predetermined angle and the sensed angle and/or the predetermined spatial position and the sensed spatial position exceeding an expected difference value.

    Abstract: A connector for placing an elongate endovascular device and an electrical accessory item into electrical connection is described. A connector body with longitudinally separated proximal and distal body ends is electrically connected to the electrical accessory item. A connection cavity extends into, and partially through, the connector body from a cavity aperture in the distal body end. At least one electrical connector contact is located in the connection cavity. The electrical connector contact is configured for longitudinal alignment with, and electrical communication to, at least a conductive portion of the endovascular device selectively present in the connection cavity. A device grasper is operable to selectively maintain the conductive portion of the endovascular device longitudinally within the connection cavity. A method and system for using the connector are also disclosed.
