A process for the recovery of copper from a copper-containing aqueous acid leach solution containing nitrate ions, in which the leach solution is contacted with a solution of an oxime extractant in a water-immiscible organic solvent, which comprises utilizing at least one of the following process variants:. The fan blade-like arrangement allows the stent to expand from the compressed condition during deployment such that likelihood of a strut or bend of the stent become entangled with a barb or adjacent strut or bend, is reduced. In some embodiments, all of the adhesives are substantially contact transparent. This removes a safety hazard at manufacturing plants by avoiding exposing workers to the contaminants generated by the plating process.
