Abstract:
1. A method for removing metal from a stent, comprising: providing a chamber having a longitudinal bore extending therethrough; inserting a stent in the chamber; attaching an end cap to one end of the chamber so that the end cap abuts the stent and moves the stent into contact with a flange in the longitudinal bore; attaching a power source to the chamber to form an anode; placing a cathode within an inner lumen of the stent; pumping an electrolytic solution through a lumen in the end cap and through the longitudinal bore and through the inner lumen of the stent to electrochemically remove portions of the inner lumen of the stent wherein the electrolytic solution has a flow rate in the range of 0.2 mL per second to 50.0 mL per second; and wherein removal of metal from the stent struts results in a transverse cross-section in the shape of an airfoil.
