| Zusammenfassung: | The constriction element consists of an inflatable hollow ring with its two ends joined together by male and female fastenings, and its inner volume (V) connected by a feed tube to an inflation source. The ring has outer (21) and inner (22) walls connected by corrugated side walls (23, 24) forming a bellows structure that creates an inward radial expansion when inflated to apply a pressure to the stomach wall. The outer wall of the ring is thicker than the inner one and has ribs (211, 212) creating an additional thickness at its outer edges.
L'invention concerne un dispositif de constriction gastrique applicable au traitement de l'obésité morbide, ce dispositif comprenant un ballonnet creux (1) gonflé par l'intermédiaire d'un conduit d'alimentation et maintenu dans une configuration en anneau par des organes mâle et femelle. Selon l'invention, le ballonnet (1) présente une structure en soufflet propre à subir, par remplissage de son volume interne (V), une expansion radiale au moins en direction de l'axe principal (Z) de l'anneau. |
