Abstract:
1. A method of manufacturing a self-supporting endoluminal implantable surface, stent, or graft, the method comprising the steps of: a. providing a self-supporting endoluminal implantable surface, stent, or graft having an inner wall surface and an outer wall surface; b. forming a pattern design into the self-supporting endoluminal implantable surface, stent, or graft; c. pre-structuring at least one of the inner wall and the outer wall surfaces by applying an athermal ablation laser machining method to the at least one wall surface to create thereon an image of a desired pattern without heat affected zones; and d. vacuum depositing material over the image of the desired pattern on the at least one wall surface to create a patterned surface overlying the at least one wall surface and including the desired pattern; e. wherein a maximum wall thickness including the patterned surface overlying the at least one wall surface measures between about 10 and about 60 microns, wherein the self-supporting endoluminal implantable surface, stent, or graft has a smooth surface finish.
