A system for differentiating between magnetic field distortion and physical movement in a hybrid magnetic and impedance tracking system can comprise a first drive patch and a second drive patch configured to generate an electrical field within the body for locating an electrode on the medical device, a magnetic localization system configured to generate a magnetic field, a magnetic sensor configured to receive signals from the magnetic localization system, and an electronic control unit configured to receive location data from the impedance localization system and magnetic sensor location data from the magnetic localization system. The electronic control circuit can be configured to detect a location change of the magnetic sensor and use the drive patch location data and magnetic sensor location data to determine whether the detected location change of the magnetic sensor is caused by a magnetic field distortion or a physical movement of the magnetic sensor.

Hybrid approach to distortion detection

The present disclosure provides a mounting assembly for attaching medical equipment to a patient table. In one particular embodiment, the present disclosure provides a mounting assembly for attaching a magnetic field generator to a patient table. The mounting assembly allows for the secure attachment of the magnetic field generator to the patient table while also allowing for easy adjustment of the positioning and location of the magnetic field generator, even after the patient is on the table. In many embodiments the mounting assembly is comprised of a mounting apparatus that attaches directly to the patient table and first and second side rails that attach to the magnetic field generator and are configured to slidably attach to the mounting apparatus. In some embodiments, the mounting apparatus and side rails are constructed of a material that provides little or no interference with the magnetic field generator.

A method for detecting and correcting for magnetic field distortions within a magnetic field used for medical magnetic localization systems may include a first set of one or more signals is indicative of the magnetic field sensed by each of the sensor coils within the metal distortion detection fixture at a first time received from the metal distortion detection fixture. A first magnitude value of the combined signals is determined. A second set of one or more signals is indicative of the magnetic field sensed by each of the sensor coils at a second time is received and a second magnitude value of the combined signals is determined. A magnetic shift in the magnetic field between the first and second magnitude values is determined. The magnetic shift is compared to a threshold shift amount indicative of a magnetic distortion in the magnetic field.

Magnetic field distortion detection and correction in a magnetic localization system

Aspects of the present disclosure are directed to systems, apparatuses, and methods for detecting and correcting for magnetic field distortions within a magnetic field used for medical magnetic localization systems.

An apparatus for use in securing a reusable medical device to an exterior surface of a patient's body includes a cushion, a first adhesive member, and a second adhesive member. The cushion includes a bottom side, a top side opposite the bottom side, and an opening adapted to receive at least a portion of the reusable medical device therein. The first adhesive member includes an upper adhesive surface and lower adhesive surface opposite the upper adhesive surface. The second adhesive member is interposed between the cushion and the first adhesive member, and includes a first adhesive surface and a second adhesive surface opposite the first adhesive surface.

An electrical feedthrough for an implantable medical device (IMD) is provided that employs a feedthrough conductor having a non-platinum based inner core and one or more layers of a conductive coating to control oxide growth on the surface of the conductor. The coating permits soldering the feedthrough conductor to IMD electronics. The resulting feedthrough provides a substantial cost savings over feedthroughs employing a solid platinum or platinum-iridium conductor.
