Abstract

Det er beskrevet en forseglet Implanterbar Innkaps- llngsanordnlng (20) for å tilføre et biologisk aktivt produkt eller funksjon til et Individ som Innbefatter en i det vesentlige Ikke-porøs kopling (32) med en Indre overflate (33) som definerer en Innløpsåpnlng (34). Et permselektlvt porøst membran (21) med en, Indre overflate (22) samvirker med koplingens Indre overflate (33) og danner et lagrlngshulrom (23) mellom | disse. Membranets Indre overflate (22) er l l det j vesentlige celle-tett, tørt, tettende Inngrep med ! koplingen (32) for å forsegle hulrommet (23). Levende celler (24) er anbragt l hulrommet (23) som kan i utsondre det biologisk aktive produktet til et Individ, i Membranet (21) er av et materiale som er Istand til å tillate passering av substanser mellom Individet og cellene som er nødvendig for å tilveiebringe det biologiske produktet eller funksjonen. Et plugglegeme (35) er anbragt i Innløpsåpnlngen (34), og er ansatt l celle-tett, tettende Inngrep med koplingens Indre overflate (33). Det er også tllvelebragt en fremgangs- måte for forsegling av den Implantere Innkapslingsan- ordnlngen (20).
