Abstract

L'invention porte sur un dispositif auto-expansible implanté dans le corps humain. Le dispositif comporte au moins un réservoir de liquide (1), des corps expansibles (4), des pompes (8, 10, 11), des tuyaux (7, 16, 18). Le réservoir de liquide (1) communique avec une extrémité d'une pompe (11) par l'intermédiaire d'un tuyau principal (2) ; l'autre extrémité de la pompe (11) communique avec les corps expansibles (4) par l'intermédiaire d'un tuyau (18). Un tuyau capillaire (13) est disposé entre le réservoir de liquide (1) et les corps expansibles (4) qui communiquent avec un réservoir à pression constante (6) par l'intermédiaire d'un tuyau (7). Le réservoir à pression constante (6) est disposé dans le réservoir de liquide (1).
