Abstract
An expandable medical device includes a plurality of elongated struts, forming a substantially cylindrical device which is expandable from a cylinder having a first diameter to a cylinder having a second diameter. A plurality of different beneficial agents can be loaded into different openings within the struts for delivery to the tissue. For treatment of conditions such as restenosis, different beneficial agents are loaded into different openings in the device to address different biological processes involved in restenosis and are delivered at different release kinetics matched to the biological process treated. The different beneficial agents may also be used to address different diseases, such as restenosis and acute myocardial infarction from the same drug delivery device.
