ABSTRACT:
An expandable medical device having a plurality of elongated struts, the plurality of elongated struts being joined together to form a substantially cylindrical device which is expandable from a cylinder having a first diameter to a cylinder having a second diameter, and the plurality of struts each having a strut width in a circumferential direction. At least one of the plurality of struts includes at least one opening extending at least partially though a thickness of the strut. A beneficial agent may be loaded into the opening within the strut. The expandable medical device may further include a plurality of ductile hinges formed between the elongated struts, the ductile hinges allowing the cylindrical device to be expanded or compressed from the first diameter to the second diameter by deformation of the ductile hinges.
