  • Method, apparatus, and electrolytic solution for electropolishing metallic stents
    Patent number: 9255341
    Abstract: An apparatus, a method, and an electrolytic solution are described for electropolishing metallic stents made, for example, of high-strength medical alloys. The apparatus may include an electropolishing container made from material of low thermal conductivity. The apparatus may include at least one spiral cathode for optimization of solution agitation and/or voltage distribution in the electrolytic solution. Further, an electrolytic solution including at least dimethylsulfate is described. A method for improved electropolishing to consistently produce smooth surfaces is also described.
    Type: Grant
    Filed: December 19, 2013
    Date of Patent: February 9, 2016
