Title
(EN) A DEVICE AND A SYSTEM FOR USE IN A PROCEDURE FOR IMPROVING A SEALING FUNCTION OF A SPHINCTER AND A METHOD FOR IMPROVING THE SEALING FUNCTION OF A SPHINCTER
(FR) DISPOSITIF ET SYSTÈME MIS EN PLACE DANS UN PROCESSUS D'AMÉLIORATION DE LA FONCTION D'OBTURATION DU SPHINCTER ET PROCÉDÉ SERVANT À AMÉLIORER CETTE FONCTION
Abstract
(EN) A system (1) and a device (3) is used in a fundoplication procedure in order to avoid over-tightening of the fundus of the stomach when the fundus is being wrapped around the oesophagus (7) adjacent the lower oesophageal sphincter (5). The device (3) comprises a catheter (8) having a primary balloon (12) located at a distal end (9) thereof which is inflatable with a saline solution by a primary pump (26). A pair of spaced apart primary stimulating electrodes (32) on the catheter (8) within the primary balloon (12) receive a stimulating current signal from a constant current signal generator (40) under the control of a microprocessor (43), which reads voltage signals from spaced apart primary receiving electrodes (35) on the catheter (8) in the balloon (12). The microprocessor (43) determines the diameter of the primary balloon (12) at locations adjacent the primary receiving electrodes (35), and an image (47) of the inflated primary balloon (12) is displayed on a visual display screen (48) along with corresponding diameter values of the primary balloon (12). The primary balloon (12) is located in the sphincter (5) and inflated with the saline solution until the sphincter (5) has been dilated to a desired diameter, which is observed on the visual display screen (45). As the fundus of the stomach is being wrapped around the oesophagus (7) adjacent the sphincter (5) the diameter of the primary balloon (12) is observed so that the fundus is not over-tightened. A secondary balloon (50) on the catheter (8) is independently inflatable for simulating a bolus of food in the oesophagus (7) so that the dilating response of the sphincter (5) can be determined by observing the image (47) of the primary balloon (12) and the diameter values thereof on the visual display screen (45).
(FR) Système (1) et dispositif (3) utilisés dans une intervention de fundoplication dans le but d'éviter un resserrement excessif du fond de l'estomac quand le fond s'enveloppe autour de l'oesophage (7) en position contiguë au sphincter oesophagien inférieur (5). Ce dispositif (3) est composé d'un cathéter (8) pourvu d'un ballonnet primaire (12) situé au niveau de l'extrémité distale (9) dudit cathéter et pouvant être gonflé au moyen d'une solution saline par une pompe primaire (26). Une paire d'électrodes de stimulation primaires équidistantes (32) sur le cathéter (8) à l'intérieur du ballonnet primaire (12) reçoit un signal de courant de stimulation d'un générateur (40) de signaux de courant continu sous le contrôle d'un microprocesseur (43) qui lit les signaux de tension électrique émis par des électrodes réceptrices primaires équidistantes (35) sur le cathéter (8) dans le ballonnet (12). Le microprocesseur (43) détermine le diamètre du ballonnet primaire (12) au niveau d'emplacements contigus aux électrodes réceptrices primaires (35) et une image (47) du ballonnet primaire (12) gonflé s'affiche sur un écran visuel (48) en même temps que des valeurs diamétrales correspondantes dudit ballonnet (12). On place ce dernier dans le sphincter (5) et on le gonfle au moyen de la solution saline jusqu'à l'obtention d'une dilatation du sphincter (5) à un diamètre désiré, ce qu'on peut observer sur l'écran visuel (45). Simultanément à l'enroulement du fond de l'estomac autour de l'oesophage (7) en position contiguë au sphincter (5), on observe le diamètre du ballonnet primaire (12), de manière à éviter un resserrement excessif du fond. Un ballonnet secondaire (50) du cathéter (8) est gonflable de façon indépendante afin de simuler un bol alimentaire dans l'oesophage (7) et de pouvoir déterminer la réaction de dilatation du sphincter (5) par observation de l'image (47) du ballonnet primaire (12) et de ses valeurs diamétrales sur l'écran visuel (45).
