Abstract

L'invention concerne un implant gastrique destiné à réduire le volume de l'estomac, dans le traitement de l'obésité et pour la régulation alimentaire. Cet implant est fabriqué à partir d'un hydrogel apte à réduire son propre volume lorsqu'il est exposé aux acides gastriques. Cette réduction de volume permet le libre passage des aliments digérés, par l'estomac et dans le duodénum, sans que l'implant n'obstrue une des ouvertures de l'estomac. Dans des modes de réalisation, l'implant selon l'invention est fabriqué à partir d'un hydrogel et peut être déshydraté pour que son volume soit réduit au minimum avant l'insertion.
