Abstract

La présente invention concerne un implant médical, et l'implant médical selon la présente invention comprend une poche et une solution saline physiologique disposée à l'intérieur de la poche, et une pièce de renfort, dont l'épaisseur est renforcée comparée aux autres pièces de la poche, formée sur la surface côté interne et/ou la surface côté externe de la poche. Selon la présente invention, les rides formées sur l'extérieur de l'implant sont réduites, permettant de là de supprimer de manière maximale la production de frottement même lorsque l'implant a été inséré dans un corps humain depuis longtemps, et d'améliorer la stabilité. De plus, selon la présente invention, la production de rides sur la surface externe de la partie supérieure sous un état vertical est réduite, permettant de là la déformation naturelle de sa forme dans la vie courante et la réduction de la sensation de corps étranger.
