Abstract

La présente invention concerne un dispositif contraceptif formant barrière destiné aux sujets de sexe féminin. Le dispositif est un corps solide réalisé dans des matériaux élastomères. Le corps solide présente une forme qui est conforme à une cavité de la zone élargie située au niveau de la partie supérieure du vagin et une concavité située sur l'extrémité supérieure du col de l'utérus. Une couche isolante circulaire zonulaire est formée entre les parties supérieure et inférieure de la paroi externe du corps solide. La couche isolante peut, dans une autre forme de réalisation, être un squelette isolant cupuliforme qui est réalisé dans des matériaux élastomères. La dureté du squelette est supérieure à celle du corps solide.
