INTRAVASCULAR STENT WITH IMPROVED VISUALIZATION PERFORMANCE AND METHOD FOR ENHANCING THE VISUALIZATION PERFORMANCE OF INTRAVASCULAR STENT

摘要

An intravascular stent especially an intracranial vascular stent wherein a stent wave rod (1) of the stent is completely wound with at least one layer of wire (2) made from a visualizable material. On the one hand the stent can ensure accurate positioning under medical imaging equipment during and after surgery; on the other hand since the wound visualizable wire (2) is located at a position on the stent subjected to no stress or to very little stress the expansion and the stress distribution of the stent is not affected so that the service life of the stent will not be shortened nor will the expected effect of the stent when in use be influenced. Also disclosed is a method for enhancing the visualization performance of an intravascular stent.
