Title
(EN) OPTICALLY GUIDED SYSTEM FOR PRECISE PLACEMENT OF A MEDICAL CATHETER IN A PATIENT
(FR) SYSTEME A GUIDAGE OPTIQUE POUR LE PLACEMENT PRECIS D'UN CATHETER MEDICAL DANS UN PATIENT
Abstract
(EN) A system is provided comprising an optically-guided catheter having a proximal end, a distal end, and at least one lumen. A light-emitting means is coupled to the catheter, the catheter is inserted into place in the patient, and light is emitted as a point or points from a selected location, usually the distal tip, of the catheter to which it is coupled. The system further comprises an external detection device that detects the transdermally projected light, emitted by the light-emitting point from within the patient, thereby indicating precise placement of the catheter within the patient.
(FR) L'invention concerne un système comprenant un cathéter à guidage optique pourvu d'une extrémité proximale, d'une extrémité distale et d'au moins une lumière. Un moyen émetteur de lumière est couplé au cathéter, lequel est inséré dans le patient, et de la lumière est émise sous la forme d'un point ou de points à partir d'un emplacement choisi, habituellement l'extrémité distale, du cathéter auquel il est couplé. Ce système comprend également un dispositif de détection extérieure qui détecte la lumière à projection transdermique émise par le point émetteur de lumière depuis l'intérieur du patient, indiquant ainsi le placement précis du cathéter à l'intérieur du patient.
