TREATMENT PROCESS FOR PRODUCING IMPLANTS OR PROSTHESES OF POLYMERS FOR CONTROLLED RELEASE OF ACTIVE INGREDIENTS

摘要

A treatment process for producing implants or prostheses of polymers for controlled release of active ingredients, characterized by a first "pretreatment" step comprising: - a phase of pressurization and heating according to controlled kinetics, - a phase of bringing the polymeric materials into contact with a supercritical fluid in batchwise mode or in continuous mode, and - a phase of depressurization with controlled kinetics, under isothermal conditions.
