Abstract
This invention is directed to a new method of mass-transfer/fabrication of micro-sized features/structures onto the inner diameter (ID) surface of a stent. This new approach is provided by technique of through mask electrical micro-machining. One embodiment discloses an application of electrical micro-machining to the ID of a stent using a customized electrode configured specifically for machining micro-sized features/structures.
