Abstract

See full text

A low-hazardous electropolishing process has been developed to remove oxide layer(s) from the surface of nitinol needles. Low concentrations of citric acid and sulfamic acid are mixed with medium concentrations of sulfuric acid to use as an electrolyte solution. The process can be easily fitted into current suture needle manufacturing processes as well as into processes require electropolishing of nitinol-containing medical devices.
