Endobronchial tube with integrated image sensor
An endobronchial tube comprising at least two lumens of different lengths for selectively associating with a patient about at least two locations relative to the tracheal carina. Said tube comprising: a first lumen having an open distal end that associates proximally to the carina within the trachea, with a first inflatable cuff; 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..
