Title (EN) SENSING A PROPERTY OF A BLADDER WALL
(FR) DÉTECTION DE PROPRIÉTÉ DE PAROI DE VESSIE
Abstract:
(EN) An apparatus for sensing a property of a bladder wall, such as bladder-wall oxygen, comprises an elongate catheter (1) and an elongate sensor (2). The catheter (1) defines a path from a proximal end of the catheter to a distal end of the catheter. The catheter comprises a sensor channel for guiding the elongate sensor along at least a part of the path, the sensor channel opening at a sensor port (3) towards the proximal end of the catheter. The sensor channel comprises (i) an enclosed lumen portion (10), arranged to surround the sensor, and (ii) an open furrow portion (16). The furrow is located nearer to the distal end of the catheter than is the enclosed lumen. The furrow is arranged to allow the sensor (2) to exit the enclosed lumen (10) in a direction substantially parallel to, or tangential to, the path of the catheter (1) at a proximal end of the furrow.
(FR) L'invention concerne un appareil pour détecter une propriété d'une paroi de vessie, telle que l'oxygène de la paroi de la vessie, qui comprend un cathéter allongé (1) et un capteur allongé (2). Le cathéter (1) définit un trajet allant d'une extrémité proximale du cathéter à une extrémité distale du cathéter. Le cathéter comprend un canal de capteur pour guider le capteur allongé le long d'au moins une partie du trajet, le canal de capteur s'ouvrant au niveau d'un orifice de capteur (3) vers l'extrémité proximale du cathéter. Le canal de capteur comprend (i) une partie de lumière enfermée (10), agencée pour entourer le capteur, et (ii) une partie de sillon ouvert (16). Le sillon est situé plus près de l'extrémité distale du cathéter que la lumière enfermée. Le sillon est agencé pour permettre au capteur (2) de sortir de la lumière enfermée (10) dans une direction sensiblement parallèle ou tangentielle au trajet du cathéter (1), au niveau d'une extrémité proximale du sillon.
