An elastic bladder is provided that is in constant fluid communication with the expandable balloon portion of a gastric band in order to automatically and continuously adjust the gastric band. The fluid pressure between the bladder and the balloon portion of the gastric band automatically and continuously adjusts so that there is no lasting pressure differential between the bladder and the expandable balloon. As the level of restriction imparted by the gastric band on the stomach of the patient changes, fluid from the bladder automatically and substantially instantaneously flows to or from the expandable balloon portion of the gastric band thereby maintaining neutral fluid pressure equilibrium between the bladder and the balloon and automatically adjusting the band to the correct level of restriction to keep the patient in the optimum zone for weight loss.
L'invention porte sur une vessie élastique en communication fluide permanente avec la partie de ballonnet extensible d'une bande gastrique dans le but d'ajuster de façon automatique et continue la bande gastrique. La pression de fluide entre la vessie et la partie de ballonnet de la bande gastrique s'ajuste de façon automatique et continue de telle sorte qu'il n'y a pas de différentiel de pression prolongé entre la vessie et le ballonnet extensible. A mesure que le niveau de restriction conféré par la bande gastrique sur l'estomac du patient se modifie, un fluide provenant de la vessie s'écoule de façon automatique et sensiblement instantanée vers ou depuis la partie de ballonnet extensible de la bande gastrique, permettant ainsi de maintenir un équilibre neutre de pression de fluide entre la vessie et le ballonnet et d'ajuster automatiquement la bande au niveau correct de restriction afin de maintenir le patient dans la zone optimale pour une perte de poids.
