METHOD AND APPARATUS FOR PRINTING RADIOPAQUE INDICIA

摘要

A method of printing radiopaque indicia on a medical device. The method includes applying radiopaque marking fluid to a surface of a plate comprising one or more etchings having a depth of at least 0.000254 centimeters, exposing the radiopaque marking fluid on the surface of the plate to air to allow the radiopaque marking fluid to achieve a sufficient level of tackiness, and transferring the radiopaque marking fluid to a médical device. The radiopaque marking fluid comprises a clear ink and tungsten particulates having a particulate size of more than one micrometer.
