Abstract: A surgical port includes a first end, a second end opposite the first end, and a longitudinal axis extending through the first end and the second end. An outer sidewall extends between the first end and the second end. First and second channels extend through the port from the first end to the second end. A first electrically conductive portion extends from the first channel to the outer sidewall, and a second electrically conductive portion extends from the second channel to the outer sidewall. The first electrically conductive portion provides a first electrically conductive path between the first channel and the outer sidewall and the second electrically conductive portion provides a second electrically conductive path the second channel and the outer sidewall. The second electrically conductive path is separate from the first electrically conductive path. Devices and methods relate to surgical ports.

Abstract: A method of operating an imaging system includes reducing common-mode current induced on a cable connected between an imaging system and an endoscope by utilizing a common-mode choke between the cable and a circuit within the endoscope, the common-mode choke being mounted within a body of the endoscope.

Abstract: An endoscope includes a body and a circuit board mounted within the body. A cable couples the circuit board to an imaging system. A common-mode choke is mounted within the body and is configured to electrically isolate the cable from the body at cautery frequencies. A method includes twisting a plurality of wires together to form a twisted set of wires. The twisted set of wires is wound around a core so that windings do not overlap, and so that a first winding and a last winding are separated from each other. Wires in the twisted set of wires are coupled to a plurality of wires in the cable. Also, these wires in the twisted set of wires are also coupled to the circuit board.
