Title
(EN) CATHETER-BASED OFF-AXIS OPTICAL COHERENCE TOMOGRAPHY IMAGING SYSTEM
(FR) SYSTÈME D'IMAGERIE DE TOMOGRAPHIE PAR COHÉRENCE OPTIQUE HORS AXE BASÉ SUR UN CATHÉTER
Abstract
(EN)
Catheter-based Optical Coherence Tomography (OCT) systems utilizing an optical fiber that is positioned off-axis of the central longitudinal axis of the catheter have many advantage over catheter-based OCT systems, particularly those having centrally-positioned optical fibers or fibers that rotate independently of the elongate body of the catheter. An OCT system having an off-axis optical fiber for visualizing the inside of a body lumen may be rotated with the body of the elongate catheter, relative to a handle portion. The handle may include a fiber management pathway for the optical fiber that permits the off-axis optical fiber to rotate with the catheter body relative to the handle. The system may also include optical processing elements adapted to prepare and process the OCT image collected by the off-axis catheter systems described herein.
(FR)
Les systèmes de tomographie par cohérence optique (OCT) basés sur un cathéter et utilisant une fibre optique qui est disposée hors axe par rapport à l'axe longitudinal central du cathéter s'avèrent beaucoup plus avantageux que les systèmes OCT basés sur un cathéter, en particulier ceux qui possèdent des fibres optiques positionnées de manière centrale ou des fibres tournant indépendamment du corps allongé du cathéter. Un système OCT doté d'une fibre optique hors axe permettant de visualiser l'intérieur d'un canal anatomique peut tourner en même temps que le corps du cathéter allongé par rapport à une partie manche. Ledit manche peut comporter une voie de gestion de fibre destinée à la fibre optique, grâce à laquelle la fibre optique hors axe peut tourner en même temps que le corps de cathéter par rapport au manche. Ce système peut également comprendre des éléments de traitement optique conçus pour préparer et traiter l'image OCT recueillie par les systèmes de cathéter hors axe ci-décrits.
