Patent ID: 7799201

Claim:
A method of electro-polishing a medical implant, comprising: establishing a predetermined cumulative current flow to be used to control an amount of time said medical implant is electro-polished; immersing said medical implant, an anode and a cathode in an electrolytic bath; contacting a surface of said medical implant with said anode, thereby forming an electrical contact; continuously moving said electrical contact between said medical implant and said anode in said electrolytic bath, thereby continuously changing said electrical contact; applying a voltage across said anode and said cathode, measuring an actual cumulative current flow between said anode and said cathode; electro-polishing said medical implant until said actual cumulative current flow reaches said predetermined cumulative current flow; and wherein said medical implant is electro-polished while being immersed in said electrolytic bath, the generation of marks on said medical implant at said electrical contact thereby being minimized.
