<p>A high intensity radiopaque contrast agent for use in a radiopaque medical device. The agent can rely on higher radiopaque concentrations per unit weight of the radiopaque element or agent. The radiopaque elements can be placed selectively on the medical device in order to enhance the radiopacity of the device with reduced amounts of the radiopaque agent. The contrast agent may be produced in various forms such as a dendrimer and/or incorporated as the end groups of polymeric chain.</p> |
