Expandable medical device for delivery of beneficial agent
First Claim
1. An expandable medical device comprising:
- at least one substantially cylindrical tube which is expandable from a first diameter to a second diameter, the substantially cylindrical tube having first portions which function as strain concentration portions and second portions which have a lower strain than the first portions during expansion of the tube from the first diameter to the second diameter, wherein the first portions are ductile hinges;
a plurality of openings, said plurality of openings formed in the second portions and none of said plurality of openings formed in the first portions; and
a beneficial agent retained in the openings.

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 through a thickness of said 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.
