CA 2523703

A medical system (100) includes a catheter (102) having an elongated tubular member (104) and an inner core (106) slideably received within the elongated member (104). The inner core (106) includes an imager(108) on a distal end (103) and is coupled with a control system (202) and an imaging system (200). The inner core (206) is configured to scan the interior of a lumen by radially rotating around a center axis (130) and axially translating along the center axis (130) while within the elongated member (104). The medical system (100) is configured to dynamically image a body lumen (302) at a high speed in order to allow for optical imaging in a safe manner without long durations of blood sequestration and displacement. The medical system (100) is configured to obtain three dimensional images of the body lumen (302) with as little as one dimensional scanning of the lumen. Images of the lumen (302) can be stored and viewed at a desired rate after scanning.

Un système médical (100) comprend un cathéter (102) possédant un élément tubulaire allongé (104) et un noyau interne (106) logé coulissant dans l'élément allongé (104). Le noyau interne (106) comprend un imageur (108) sur son extrémité distale (103) et est couplé à un système de commande (202) et à un système d'imagerie (200). Le noyau interne (206) est configuré pour balayer l'intérieur d'une lumière par rotation radiale autour d'un axe central (130) et pour se déplacer par translation axiale le long de l'axe central (130) alors qu'il se trouve dans l'élément allongé (104). Le système médical (100) est configuré pour restituer en image une lumière corporelle (302) à grande vitesse afin de permettre une imagerie optique de manière sûre sans séquestration et déplacement de longue durée du sang. Le système médical (100) est configuré pour produire des images tridimensionnelles de la lumière corporelle (302) avec seulement un balayage dimensionnel de la lumière. Les images de la lumière (302) peuvent être stockées et visualisées à la vitesse voulue après le balayage.
