This invention provides cell encapsulating devices capable of maintaining large numbers of viable cells. The devices are comprised of an inert,substantially cell-free core, a permeable membrane and a zone for maintaining cells. The permeable surrounds the core such that the zone of cells is bounded by the core and the permeable membrane. The devices of the invention are suitable for implantation into an individual in need of treatment and are capable of supplying therapeutic substances to such individuals.
L'invention porte sur des dispositifs d'encapsulage de cellules, permettant de conserver un grand nombre de cellules viables. Les dispositifs sont constitués d'un noyau inerte, pratiquement exempt de cellules, d'une membrane perméable et d'une zone pour la conservation des cellules. La membrane perméable entoure le noyau de telle façon que la zone de cellules soit limitée par le noyau et la membrane. Ces dispositifs peuvent être implantés chez des personnes nécessitant un traitement, pour leur fournir des substances thérapeutiques.
