METHOD AND DEVICE FOR THE MANUFACTURE OF THE MEDICAL EXPANDING STENTS

摘要

Method and device for manufacturing of expandable cylindrical metal meshes for use in expandable stents and in particular for customized manufacturing. The method includes determining the type and size of the stent to be implanted, electrochemically forming the stent with desired pattern of meshes and implanting the stent into patient. The method comprises using a cathode with desired pattern of meshes and a tubular blank, from which the stent is formed. Between the cathode and the blank is delivered an electrolyte and the cathode and the blank are simultaneously rotated during electrochemical forming process.
