Electro-polishing fixture and electrolyte solution for polishing stents and method

摘要

An electro-polishing fixture for polishing stents which incorporates multiple anodes in contact with the stent and a center cathode disposed coaxially within the interior of the stent and a curved exterior cathode disposed about the perimeter of the stent. The invention further includes an electrolyte solution adapted for polishing stents composed of nickel-titanium alloy and a method of using the electrolyte in combination with the electro-polishing fixture.
