Abstract: An apparatus includes two or more medical systems and a low impedance path. The two or more medical systems have respective electrical outputs and respective separate isolation grounds each isolated from power lines and from earth ground, wherein the two or more medical systems are electrically coupled one with the other via the patient. The low impedance path connects the separate isolation grounds of the medical systems to one another, causing one or more leakage currents to flow via the low impedance path instead of via the patient.

Abstract: An apparatus includes a camera and a processor. The camera is configured to capture images of a display of a temperature measurement system that displays a tissue temperature. The processor is configured to analyze the captured images to extract a numerical value of the tissue temperature displayed by the temperature measurement system, and initiate an action responsively to the extracted numerical value.

Abstract: A method includes registering a first coordinate system of a fluoroscopic imaging system and a second coordinate system of a magnetic position tracking system. A three-dimensional (3D) map of an organ of a patient, which is produced by the magnetic position tracking system, is displayed. A 3D volume that would be irradiated by the fluoroscopic imaging system is calculated using the registered first and second coordinate systems. The calculated 3D volume is marked on the 3D map.

Abstract: A method for producing a coil assembly includes overlaying printed circuit traces on a core. The traces include terminals for coupling to conductive connections on a base on which the coil assembly is to be mounted. Two or more wires are wrapped around the core so as to define two or more coils, wrapped in different, respective directions. The ends of the wires are coupled to the printed circuit traces, so as to connect the wires through the traces to the terminals.

Abstract: Orthopaedic operating systems, operating rooms, computer aided surgical methods, trackable implants, instruments and surgical planning and IGS software applications are described. The integrated surgical system is for use in an orthopaedic operating room to enable a surgeon to carry out a computer aided surgical procedure on a subject. A subject support, wireless magnetic tracking system, registration system, at least a first display device, a control system and a surgeon interface operable by the surgeon to control operation of the plurality of parts of the integrated surgical system are provided.
