Title
(EN) TETHERED CAPSULE ENDOSCOPE FOR BARRETT'S ESOPHAGUS SCREENING
(FR) ENDOSCOPE DE TYPE CAPSULE CAPTIVE DESTINE A L'EXPLORATION DE L'OESOPHAGE DE BARRETT
Abstract
(EN)
Capsule (20) is coupled to a tether (22) that is manipulated to position the capsule and a scanner (26) included within the capsule at desired location within a lumen in a patient's body. Images produced by scanner can be used to detect Barrett's Esophagus (BE) and early (asymptomatic) esophageal cancer after capsule is swallowed and positioned with the tether to enable the scanner in the capsule to scan a region of the esophagus above the stomach to detect a characteristic dark pink color indicative of BE. The scanner moves in a desired pattern to illuminate a portion of the inner surface. Light from the inner surface is then received by detectors in the capsule, or conveyed externally through a waveguide to external detectors. Electrical signals are applied to energize an actuator (28) that moves the scanner. The capsule can also be used for diagnostic and/or therapeutic purposes in other lumens.
(FR)
Selon l'invention, une capsule est couplée à une attache manipulée de façon à positionner la capsule et un scanneur logé à l'intérieur de cette dernière à un emplacement désiré dans une lumière du corps d'un patient. Des images produites par le scanneur peuvent être utilisées pour détecter l'oesophage de Barrett (BE) et un début de cancer oesophagien (asymptomatique) après que la capsule soit avalée et mise en place avec l'attache pour permettre au scanneur logé dans la capsule d'explorer une région de l'oesophage située au-dessus de l'estomac afin de détecter une couleur rose sombre caractéristique du BE. Le scanneur se déplace selon une configuration désirée afin d'éclairer une partie de la surface intérieure. La lumière émanant de la surface intérieure est ensuite reçue par des détecteurs placés dans la capsule, ou acheminée par un guide d'onde vers l'extérieur et des détecteurs externes. Des signaux électriques sont appliqués pour alimenter un actionneur qui déplace le scanneur. La capsule peut également être utilisée dans d'autres lumières à des fins diagnostiques et/ou thérapeutiques.
