Patent ID: 8268382

Claim:
A method of making a stent including hollow struts comprising the steps of: utilizing a substantially cylindrical substrate at least partially made from a sacrificial material; depositing a first photoresist layer on the substrate; patterning the first photoresist layer to provide openings in the first photoresist layer; depositing a first metal layer on the substrate in the openings of the patterned first photoresist layer; depositing a second photoresist layer over the first metal layer; patterning the second photoresist layer to provide openings in the second photoresist layer, wherein the openings in the second photoresist layer are provided over the first metal layer; depositing a sacrificial material on the first metal layer in the openings of the second patterned photoresist layer; depositing a third photoresist layer over the sacrificial material and the first metal layer; patterning the third photoresist layer to provide openings in the third photoresist layer; depositing a second metal layer in the openings of the patterned third photoresist layer; removing the first, second and third photoresist layers; and removing the substrate and the sacrificial material.
