PATTERN TRANSFER DEVICE FOR MASS TRANSFER OF MICRO-PATTERNS ONTO MEDICAL DEVICES

摘要

This invention is directed to a pattern transfer device and assembly for 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.

主权项

1. A patterned masked electrode, comprising:
a. An generally cylindrical electrically conductive electrode member having an outer surface; b. A non-conductive coating on the outer surface of the electrode member; and c. A micro-pattern defined in the non-conductive coating passing through the non-conductive coating and exposing defined portions of the electrode member.
