ABSTRACT:
The combination of a transparent medical tube and a flexible light conductor slidably and removably disposed therein, and the method of use of that combination. The medical tube is formed of relatively soft, highly-flexible, thermoplastic material and has an open proximal end and a distal end wall with sidewall openings adjacent thereto. The light conductor fits closely within the lumen of the medical tube, with its distal end disposed adjacent to the tube's distal end wall and a handle at its proximal end coupled to the proximal end of the tube. Because of its greater stiffness, the conductor facilitates insertion of the tube/conductor combination without buckling or independent twisting of the tube; however, because the two are secured together at their proximal ends, torquing forces applied to the handle of the conductor are transmitted to the tube for aiding in directing and advancing the tube/conductor combination. Light transmitted by the conductor to its distal end passes outwardly through the medical tube's distal end wall and may be visually and externally observed through the body wall of the patient.
