Title (EN) METHOD AND SOLUTION FOR ELECTROPOLISHING STENTS MADE OF HIGH STRENGTH MEDICAL ALLOYS
(FR) PROCÉDÉ ET SOLUTION POUR LE POLISSAGE ÉLECTROLYTIQUE DE STENTS FAITS D'ALLIAGES MÉDICAUX À HAUTE RÉSISTANCE
Abstract:
(EN) An apparatus and method are described for electropolishing metallic stents made 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 is described. A method for improved polishing to consistently produce smooth surfaces is described.
(FR) Cette invention concerne un procédé et un appareil de polissage de stents faits d'alliages médicaux à haute résistance. L'appareil peut comprendre un réservoir pour polissage électrolytique fait d'un matériau à faible conductivité thermique. L'appareil peut également être équipé d'au moins une cathode spiralée destinée à optimiser l'agitation de la solution et/ou la répartition de la tension dans la solution électrolytique. Est également décrit une solution électrolytique ainsi qu'un procédé de polissage permettant d'obtenir systématiquement des surfaces lisses.
