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 strut (1) of the stent is completely wound with at least one layer of wire (2) made from a visualizable material. The stent can ensure accurate positioning under medical imaging equipment during and after a surgery. In addition, since the wound visualizable wire (2) is located at a position on the stent subjected to little or no 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 in use be influenced. Also disclosed is a method for enhancing a visualization performance of an intravascular stent.
