  • Patent number: 7520891
    Abstract: Provided herein is a poly(ester amide) (PEA) polymer blend and a polymeric coating containing the PEA polymer blend. The PEA polymer blend has a Tg above the Tg of poly(ester amide benzyl ester) (PEA-Bz) or the Tg of poly(ester amide TEMPO). The PEA polymer blend can form a coating on an implantable device, one example of which is a stent. The coating can optionally include a biobeneficial material and/or optionally with a bioactive agent. The implantable device can be used to treat or prevent a disorder such as one of atherosclerosis, thrombosis, restenosis, hemorrhage, vascular dissection or perforation, vascular aneurysm, vulnerable plaque, chronic total occlusion, claudication, anastomotic proliferation for vein and artificial grafts, bile duct obstruction, ureter obstruction, tumor obstruction, and combinations thereof.
