Abstract
A composite stent and methods for making the same are provided. In one embodiment a regioselective band is formed in situ on the stent. In one embodiment, the band is made of a regioselective material having a high creep compliance and having a second modulus of elasticity lower than that of a structural material comprising the stent. In one embodiment, the regioselective material is drip-coated or dip-coated on the stent near the ends. In one embodiment, the regioselective material includes a therapeutic agent, which may be a radioactive emitter, an anti-platelet drug, or an anti-proliferative drug.
