Claim:
1. A biocompatible device capable of releasing superoxide comprising: a substrate; and a biocompatible material comprising at least one semi-crystalline, hydrolytically degradable polymeric material, the polymeric material having been subjected to ionizing radiation at a dose rate less than about 50 kGy and sterilized by non-ionizing radiation methods; said polymeric material being in contact with at least a portion of said substrate, wherein said at least one semi-crystalline, hydrolytically degradable polymeric material comprises a first polymeric material and a second polymeric material, wherein at least one of said first and second polymeric materials comprises stabilized free radicals; wherein said first polymeric material and said second polymeric material have been subjected to different doses of ionizing radiation, and wherein the biocompatible material, upon contact with aqueous media, enable multi-phasic generation of reactive oxidative species.
