  • the invention relates to bougie, adapted for inserting the appliance into the fundus of the stomach.
  • treatment methods have been propos 25 wherein the interior volume of the stomach, is only temporar reduced by causing the patient to swallow an inflatable balloon which is inflated after it reaches the stomach.
  • the inflated balloon serves to substantially reduce the interior volume of the stomach such 30 that ingestion of a relatively small amount of food will cau distension of the stomach.
  • Such distension causes excitatio of certain neuroreceptors in the sub-mucosa of the stomach * ⁇ lying in the upper fundus.
  • Excitation of these neurorecep ⁇ tors which are endings of the vagus nerves of the gastric ⁇ 35 plexus, causes the patient to experience the sensation of satiety even though the patient has ingested only a rela ⁇ tively small amount of food.

  • the implacement of the collapsible structure is accomplished by collapsing the semi-rigid skeleton thereof by applying external force to deform the structure to a shape and cross-sectional dimension which is insertable through the esophagus and cardiac opening, per-orally inserting the collapsed structure into the fundus and releasing the col ⁇ lapsing force to cause the collapsed structure to autogenously re-assume its normal uncollapsed shape.

  • the bougie device 16 also includes a suitable ejector rod 18, operable through the upper end 19 of the bougie.
  • Movement of the rod 18 in the direction of the arrow A exerts force on an internal piston portion 20 formed on the lower end of the rod 18 which, in turn, exerts force upon the collapsed appliance 10, causing it to be ejec from the bougie 16 through the open lower end 21 thereof.

  • Removal of the appliance can be effected by various means including surgical invasion or retrieval through the esophagus by endoscopic techniques. In certain applications, it may be desirable to form the entire appliance of biodegrada materials such that the device will dissolve after a pre-selec period of time in the stomach and be passed from the body through the digestive tract.

Abstract

On traite l'obésité morbide par l'introduction dans le grand cul-de-sac de l'estomac d'un appareil de forme creuse. L'appareil (10) est constitué par des éléments (11) d'ossatures semi-rigides et peut être réduit à une dimension et à une forme lui permettant d'être introduit dans l'estomac par l'oesophage et le cardia. Après déclenchement dans l'estomac du dispositif replié, il reprend de manière autogène sa forme normale non repliée.
