Abstract
Système destiné à l'apport de substances à un milieu environnant, notamment de substances médicamenteuses, comprenant la substance contenue dans une matière polymère formant une cavité. La matière polymère est un copolyester thermoplastique segmenté élastomère formé de motifs d'esters à chaîne longue et de motifs d'esters à chaîne courte, notamment de téréphtalate de butylène et de téréphtalate d'un poly (oxyalkylène). Le système peut avoir par exemple la forme d'un petit sac formé de deux minces pellicules 12, 13 du copolyester soudées par leurs bords de manière à former une cavité 15 contenant le médicament 17.
