A stent or intraductal medical device manufactured from a tubular member having an inner tube tightly fitted into an outer tube is provided. Microdepots may be formed on the outer surface of the inner tube, and may contain radioactive, radiopaque or therapeutic substances. A method for manufacturing such a medical device or stent is also described. The material to be deposited on the inner tube may be deposited on the inner tube by dipping or immersion, or the material may be applied to the inner tube using micro-injection or electrodeposition. The material to be deposited may be applied to cavities or microdepots formed in the outer surface of the inner tube. Excess material may be removed from the inner tube by centrifugation or shaking, and the material to be deposited may be heated to bond the material to the surface of the microdepots on the inner tube. |
