Claim:
1. A catheter for trachea-bronchial suction comprising: a disposable catheter comprising a tubular body having a proximal and a distal end; a suction channel extending through the tubular body of the catheter and equipped to be connected to a vacuum source; a handle coupled to the proximal end of the tubular body and having two attachment elements each having a different shape from the other, wherein one attachment element has a first substantially cylindrical portion and a tapered end portion and the other attachment element has a frusto conical attachment; a visualization unit removably connected to said tubular catheter by the two attachment elements, the visualization unit comprising a light source, a camera and a viewer, wherein the tubular body of the catheter is made with a greater thickness in central and proximal parts of the tubular body relative to a distal part of the tubular body, wherein a cross-section of the central part of the tubular body is one of a substantially square or triangular shape and a cross-section of the distal end of the tubular body is of a substantially circular shape, so as to stiffen the tubular body and enable the tubular body to resist twisting, and wherein the tubular body includes optical fibers extending to the distal end for transferring images and light between the visualization unit and the distal end.
