Provided herein is a copolymer that includes a soft block (A) that
contains poly(ester amide) (PEA) and a hard block (B). The copolymer can
be any of AB, ABA or BAB type block copolymers. By varying the relative
amount of the PEA block and the hard block, one can obtain a copolymer
with a T.sub.g for mechanical integrity in drug-delivery stent
applications. The copolymer can be used alone or optionally in
combination with a biobeneficial material and/or a biocompatible polymer
to form an implantable device or a coating on an implantable device. When
the copolymer is used in combination with a biobeneficial material, the
copolymer and the biobeneficial material can be co-deposited or applied
in sequence during the coating process. A coating formed of the copolymer
may also include a bioactive agent. The implantable device can be
implanted in a patient to treat, prevent, or ameliorate a disorder such
as 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, and/or
tumor obstruction.
