Title
(EN) POSITIONING A TUBE IN A LUMEN VIA TRANSILLUMINATION
(FR) POSITIONNEMENT D'UN TUBE DANS UNE LUMIÈRE PAR TRANSILLUMINATION
Abstract
(EN)
An illumination system for illuminating a lumen within a body of a patient comprising a tube having a proximal end and an opposed distal end and an internal chamber, the tube being configured for placement within a lumen of the body. The system also includes an illumination subsystem including an optical fiber that is sized and configured to seat within the internal chamber of the tube and a light source for generating light that is emitted by the fiber optic cable. The optical fiber, when mounted within the tube and when the light source generates light, emits light at the distal end of the tube so as to transilluminate the lumen and surrounding tissue so as to be able to locate the distal end of the tube within the lumen of the patient.
(FR)
L'invention concerne un système d'éclairage pour éclairer une lumière à l'intérieur d'un corps d'un patient, comprenant un tube présentant une extrémité proximale et une extrémité distale opposée et une chambre interne, le tube étant conçu pour être placé à l'intérieur d'une lumière du corps. Le système comprend également un sous-système d'éclairage comprenant une fibre optique qui est dimensionnée et conçue pour se poser à l'intérieur de la chambre interne du tube et une source lumineuse pour générer de la lumière qui est émise par le câble à fibre optique. La fibre optique, lorsqu'elle est montée à l'intérieur du tube et lorsque la source lumineuse génère de la lumière, émet de la lumière au niveau de l'extrémité distale du tube de façon à transilluminer la lumière et le tissu environnant de façon à pouvoir localiser l'extrémité distale du tube à l'intérieur de la lumière du patient.
