Abstract

A variety of phase-separated biocompatible polymer compositions are described. In preferred embodiments the polymers are bioresorbable and/or biodegradable, and have desirable mechanical properties, such as fracture and/or fatigue toughness, that have previously not been a primary design criteria for such polymers. The polymer compositions are useful in a variety of medical applications, such as in the fabrication of medical devices.
