1. An endobronchial tube comprising:

  • an outer wall defining a first lumen having an open distal end, a second lumen having an open distal end, a dedicated image sensor lumen, and a dedicated cleaning lumen;

    wherein the outer wall defines a first section extending from a proximal end of the outer wall to the distal end of the first lumen and a second section extending from the distal end of the first lumen to the distal end of the second lumen;

    wherein the second section has a smaller outer circumference than the first section;

    a first inflatable cuff mounted to the first section of the outer wall;

    a second inflatable cuff mounted to the second section of the outer wall;

    an image sensor and an illumination source disposed entirely within said dedicated image sensor lumen, wherein the dedicated image sensor lumen has a distal end adjacent the distal end of said first lumen;

    said dedicated cleaning lumen having a plurality of cleaning nozzles positioned distal to the image sensor and illumination source, the plurality of cleaning nozzles comprising a primary cleaning nozzle and a secondary cleaning nozzle disposed axially distal of the primary cleaning nozzle;

    wherein said cleaning nozzles comprise apertures extending from said dedicated cleaning lumen through a thickness of the outer wall and opening through an exterior surface of the second section of the outer wall to direct fluid substantially perpendicular to a long axis of the outer wall adjacent to said image sensor and said illumination source; and

    an image sensor connector communicatively coupled with the image sensor and disposed at said proximal end of said outer wall.
