A stent or intraductal medical device is provided having radiopaque marker material deposited on the surface of the stent or medical device to assist visualization of the device during implantation. A method for depositing a radiopaque material on an implantable medical device such as a stent is also described. The radiopaque material may be deposited on the medical device by dipping or immersion, or the radiopaque material may be applied to the device using micro-injection or electrodeposition. The radiopaque material may coat the entire surface of the stent, or only a portion of the stent, or it may be applied to cavities or microdepots formed in the outer surface of the medical device. Excess radiopaque material may be removed from the device by centrifugation or shaking, and the radiopaque material may be heated to bond the material to the surface of the device.
