Abstract
An expanding vascular stent is disclosed that is inserted into a blood vessel in the human body and expands the blood vessel. The stent is configured in such a way that adjacent rows, each of which is comprised of a plurality of identical cells, are symmetrically arranged, in an out of phase manner. When the stent is expanded in the radial direction, the adjacent rows are expanded in opposite directions, maintaining their linearly symmetrical state. Therefore, the reduction in the length of the stent can be minimized. Since the stent has also a great degree of flexibility, when it is inserted into the blood vessel, it can minimize the damage to the blood vessel wall.
