Summary for Patent: 4,957,119
Title: Contraceptive implant
Abstract:The invention relates to an implant of polymeric material which can release a contraceptive agent for a relatively long time when fitted subcutaneously or locally. The implant comprises a core material of ethylene/vinyl acetate copolymer which functions as a matrix for a contraceptive substance, an ethylene/vinyl acetate membrane encasing the core material, and a contact layer at the interface of the core material and membrane which prevents the separation of the core material from the membrane. The implant of the invention is made by a co-extrusion process.
