Abstract
The metal reinforced polymer stent for use in blood vessels is formed of a thin planar sheet of metal, and is laminated on at least one side with a thin film of a polymer capable of absorbing and releasing therapeutic drugs. The thin planar sheet of metal is formed as a sheet and cut in a shape that can be used as a stent, the ends of which can be joined in a contractible, expandable loop.
