An expandable medical device includes elongated struts which are joined together to form a substantially cylindrical device. The device is expandable from a cylinder having a first diameter to a cylinder having a second diameter. Each of the struts has a width in a circumferential direction and a thickness. At least one of the struts includes at least one opening that extends at least partially through the strut's thickness. A beneficial agent may be loaded into the opening within the strut. The expandable medical device may also include ductile hinges, formed between the elongated struts, which deform to allow the cylindrical device to be expanded or compressed from the first diameter to the second diameter.
