Abstract
A medical device is loaded with a number of therapeutic agents using a corresponding method to apply a medicated ink mark. The resulting medical device can include surface activation of an immobilizing medication, controlled medication release, and the ability to use dyes or pigments to delineate different active ingredients by location and dosage. The active medicinal compounds can be placed on selective areas of the medical device. The medical device having the medicated ink mark can provide a detectable and dosemetric controllable delivery to a specific targeted and localized location to provide the maximum therapeutic benefit. The medicated ink may be applied to the medical device by a number of different methods, by a manufacturer or by the user at the time of medical device use. Dimensions of the markings printed onto the medical device can further serve to control and identify to the user the dosage amount of the medical agent available on the marked medical device. Multiple types of medical agents with multiple application methods can be used. The medicated ink can be dyed, pigmented, or used as a colorless vehicle for the compound of interest, and can be formulated to incorporate either immobilized or exuding active agents onto the medical device.
