摘要：
The invention relates to a delivery device for the controlled release of a therapeutically active agent, especially a progestin or an estrogen, over a prolonged period of time, said device including a core which contains the therapeutically active agent, and a membrane encasing the core wherein said membrane is made of an elastomer. According to the invention, the elastomer is a siloxane-based elastomer which includes 3, 3,3-trifluoropropyl groups attached to the Si-atoms of the siloxane units.Avgivelsesinnretning for kontrollert frigivelse av et terapeutisk aktivt middel, spesielt progestin eller østrogen, over en lengre tidsperiode. Innretningen omfatter en kjerne som omfatter det terapeutisk aktive middel og en membran fremstilt av en elastomer sor omgir kjernen. Elastomeren er en siloksanbasert elastomer omfattende 3,3,3-trifluorpropylgnr bundet til Si-atomene i siloksanenhetene.
