Abstract
A bilayer mold for forming polymer microstructures is provided. The bilayer mold includes a rigid plastic cylinder having slots defined along an outer periphery of the rigid plastic cylinder; and a layer of plastic elastic polymer material disposed within the slots and having indents defined therethrough and in the rigid plastic cylinder. The indents have a first profile extending through the layer of plastic elastic polymer and terminating within the rigid plastic cylinder. A metal polymer structure profile is also provided using laser-etching of a desired shape for the features of the microstructures in a metallic foil, followed by further refining of the features. The polymer and metal microstructures can be formed on the surface of a stent to facilitate retention of the stent.
