From: Low-cost prototyping of nitinol wires/frames using polymeric cores and sacrificial fixtures with application in individualized frames anchoring through the atrial septum

EDS analysis results for: (a) The surface of an untreated nitinol wire and (b) A nitinol wire after going through the proposed process. Al, Si, and C signatures could be attributed to the ambient dust/residues since they are not present in the chemical processing (e.g., etching copper). The analysis did not show any trace of copper.
