a second lumen having an open distal end that extends distally, past the Carina and associates within one of the Left Bronchial branch and Right Bronchial branch with a second inflatable cuff; a dedicated image sensor lumen spanning the length of said first lumen, the dedicated image sensor lumen comprising an image sensor and illumination source disposed adjacent to the distal end of said first lumen, and configured to provide an image of the Tracheal bifurcation of the Tracheal Carina, the openings of the Left Bronchial branch, and the opening Right Bronchial branch; and at least one dedicated cleaning lumen disposed parallel with said dedicated image sensor lumen along the length of said endobronchial tube and wherein said cleaning lumen is configured to forms a cleaning nozzle at the distal end, wherein said cleaning nozzle is directed toward said image sensor lumen at its distal end. ## Claims ### Claim 1 An endobronchial tube comprising: a first lumen having an open distal end; a first inflatable cuff; a second lumen having an open distal end; a second inflatable cuff distal to the open distal end of the first lumen; a dedicated image sensor lumen located at least partially within a wall of said endobronchial tube, the dedicated image sensor lumen comprising a distal end; an image sensor and an illumination source, disposed in the dedicated image sensor lumen adjacent the open distal end of said first lumen; at least one dedicated cleaning lumen disposed within said wall of said endobronchial tube, the at least one dedicated cleaning lumen having a distal end, wherein said at least one dedicated cleaning lumen curves at the distal end of the dedicated cleaning lumen to form a cleaning nozzle having an opening in an external surface of the dedicated image sensor lumen distal to the image sensor, and wherein the dedicated image sensor lumen comprises a tubular surface within the wall of the endobronchial tube and a partially annular surface extending from the tubular surface, the partially annular surface forming the external surface of the endobronchial tube on which the opening of the cleaning nozzle is located. ### Claim 2 (depends on 1) The endobronchial tube of claim 1, wherein said cleaning nozzle is provided with a diameter from 0.1 mm to 2 mm. ### Claim 3 (depends on 2) The endobronchial tube of claim 2, wherein said diameter is 0.6 mm. ### Claim 4 (depends on 1) The endobronchial tube of claim 1, wherein said endobronchial tube is provided with two or more cleaning nozzles, including said cleaning nozzle, about different sides of said image sensor. ### Claim 5 (depends on 4) The endobronchial tube of claim 4, wherein said two or more cleaning nozzles cooperate with one another. ### Claim 6 (depends on 1) The endobronchial tube of claim 1, wherein said at least one dedicated cleaning lumen provides for flushing a field of view of the image sensor. ### Claim 7 (depends on 6) The endobronchial tube of claim 6, wherein the cleaning nozzle is aimed proximally toward the image sensor to clear the field of view of the image sensor. ### Claim 8 (depends on 1) The endobronchial tube of claim 1, further comprising a second image sensor lumen and a second image sensor disposed in the second image sensor lumen. ### Claim 9 (depends on 1) The endobronchial tube of claim 1, wherein said image sensor is a CCD image sensor or CMOS image sensor. ### Claim 10 (depends on 1) The endobronchial tube of claim 1, wherein said light source is selected from the group consisting of a LED, optical fibre, waveguide, light guide, and any combination thereof. ### Claim 11 (depends on 1) The endobronchial tube of claim 1, adapted for non-invasive insertion through an oral cavity or a nasal cavity. ### Claim 12 (depends on 1) The endobronchial tube of claim 1, adapted for insertion through an external port or an incision. ### Claim 13 (depends on 1) The endobronchial tube of claim 1, adapted for insertion through surgery or other invasive procedure. ### Claim 14 (depends on 1) The endobronchial tube of claim 1, wherein the at least one dedicated cleaning lumen comprises a first cleaning lumen and a second cleaning lumen. ### Claim 15 (depends on 14) The endobronchial tube of claim 14, wherein the first cleaning lumen provides for flushing a biological obstruction and the second cleaning lumen provides for suctioning the biological obstruction or another biological obstruction. ### Claim 16 (depends on 15) The endobronchial tube of claim 15, wherein the first cleaning lumen has a different diameter than the second cleaning lumen. ### Claim 17 (depends on 14) The endobronchial tube of claim 14, wherein the first cleaning lumen and the second cleaning lumen are disposed on different sides of the image sensor. ### Claim 18 An endobronchial tube comprising: a first lumen having an open distal end; a first inflatable cuff; a second lumen having an open distal end; a second inflatable cuff distal to the open distal end of the first lumen; a dedicated image sensor lumen located at least partially within a wall of said endobronchial tube; an image sensor and an illumination source, disposed in the dedicated image sensor lumen adjacent the open distal end of said first lumen; and at least one dedicated cleaning lumen disposed within said wall of said endobronchial tube, wherein said at least one dedicated cleaning lumen includes a longitudinal portion disposed substantially parallel to the dedicated image sensor lumen and a cleaning nozzle fluidly coupled to the longitudinal portion and having an opening in an external surface of the dedicated image sensor lumen distal to the image sensor, and wherein the dedicated image sensor lumen comprises a tubular surface within the wall of the endobronchial tube and a partially annular surface extending from the tubular surface, the partially annular surface forming the external surface of the endobronchial tube on which the opening of the cleaning nozzle is located. ### Claim 19 (depends on 18) The endobronchial tube of claim 18, wherein the surface of the dedicated image sensor lumen on which the cleaning nozzle is located comprises an open surface. ### Claim 20 (depends on 18) The endobronchial tube of claim 18, wherein the dedicated image sensor lumen has a distal end and a proximal end and is provided with a radius that is larger at the distal end than at the proximal end. ### Claim 21 (depends on 18) The endobronchial tube of claim 18, wherein the cleaning nozzle consists of a hole between surfaces of the wall, and wherein the hole connects the longitudinal portion of the at least one dedicated cleaning lumen to the opening in the surface of the dedicated image sensor lumen.
