Medical imaging device with electrical noise mitigation

An intrusive medical device comprising:

• a proximal end and a distal end spaced apart from the proximal end;
• a tubular member including a lumen therein, the tubular member extending from the proximal end to the distal end;
• a camera and a light source positioned at the distal end;
• and
• a cable bundle consisting of a first coaxial cable and a second coaxial cable within a common electrical shield, the cable bundle extending from the proximal end to the distal end and electrically connected to the camera and light source at the distal end;
• the first coaxial cable comprising a first cable central conductor, a first cable insulating layer, and a first cable shield;
• the second coaxial cable comprising a second cable central conductor, a second cable insulating layer, and a second cable shield;
• one of the first cable shield or the second cable shield being electrically connected to the light source and configured to supply power to the light source;
• the other of the first cable shield or the second cable shield being electrically connected to the camera and configured to supply power to the camera;
• one of the first cable central conductor or the second cable central conductor being electrically connected to the camera and configured to transfer a video signal;
• the other of the first cable central conductor or the second cable central conductor being electrically connected to the camera and configured to transfer a clock signal;
• and
• the common electrical shield electrically connecting a ground to the camera and the light source.
