The present invention provides biodegradable, biocompatible bis -(.alpha.- amino acyl)-diol-diester-containing poly(ester amide) (PEA) and poly(ester urethane) (PEUR) co-polymer compositions with mechanical properties that can be readily tailored by selection of various combinations and proportions of the building blocks of the co-polymers. The compositions are suitable for use in production of drug-releasing biodegradable particles and implantable surgical devices, such as stents and internal fixation devices. The co-polymer compositions, particles and surgical devices biodegrade in vivo by enzymatic action to release bioactive agents in a controlled manner over time as well as biocompatible breakdown products, including one to multiple different amino acids.

La présente invention concerne des formules biodégradables et biocompatibles de copolymères poly(ester amide) (PEA) et poly(ester uréthane) (PEUR) contenant des diesters de bis-(.alpha.-amino acyl)-diol dont les propriétés mécaniques peuvent être facilement ajustées par la sélection de diverses combinaisons et proportions des motifs constitutifs des copolymères. Les formules sont adaptées à un emploi dans la production de dispositifs chirurgicaux implantables et de particules biodégradables pour diffusion d'un médicament, tels que des endoprothèses et des dispositifs de fixation interne. Les formules de copolymère, les particules et les dispositifs chirurgicaux se dégradent in vivo par action enzymatique pour libérer les agents bioactifs d'une façon contrôlée dans le temps, de même que des produits de dégradation biocompatibles, incluant un à plusieurs acides aminés différents.
