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.
A stent for use in maintaining the patency of blood vessels, the stent comprising: a metal reinforcement member having first and second side surfaces, said reinforcement member having first and second ends and a main body portion between the first and second ends, said reinforcement member being cap
A stent for use in maintaining the patency of blood vessels, the stent comprising: a metal reinforcement member having first and second side surfaces, said reinforcement member having first and second ends and a main body portion between the first and second ends, said reinforcement member being capable of being rolled up into a cylindrical configuration whereby the first end overlaps the second end, said first end of the reinforcement member comprising a surface extending in a plane end defining a slot for receiving the second end, the second end and the main body portion being insertable through said slot so as to form a loop, said slot in the first end having a plurality of teeth for releasably engaging the second end and the main body portion, said plurality of teeth extending from said slot at an angle of about 45°out of the plane of the first end of the reinforcement member, and the second end and the main body portion having a corresponding plurality of apertures for receiving said plurality of teeth to adjustably retain the second end and the main body portion in said slot, whereby when said reinforcement member is in said cylindrical configuration, said slot and said means for releasably engaging said slot permit radial expansion of said reinforcement member and resist radial compression of said reinforcement member; and at least one layer of a polymer bonded to at least one of the side surfaces of the reinforcement member, said polymer being capable of absorbing and releasing therapeutic drugs.
