Abstract
The present invention relates to a vascular stent comprising wide vertical branches and narrow horizontal branches having wave-form projections, which has a vertically denser distribution. The vascular stent of the present invention comprises stainless steel-based vertical branches and horizontal branches having wave-form projections. The widths of the vertical branch and horizontal branch range 0.09 to 0.12 mm and 0.05 to 0.09 mm, respectively, while each thickness of those are identical to each other and range 0.08 to 0.12 mm. The vascular stent of the invention provides so superior flexibility as to afford excellent adaptability to the anatomy of the vessel. Moreover, the dense distribution of the branches improves strength of stability of the vascular stent, which allows the stent to sufficiently expand against high recoiling force. Implantation of the vascular stent to patients with coronary artery obrustructive disease (CAOD) can restore the constricted blood vessels to the original state, which normalizes the blood flow rate, and further, decreases the restenosis rate as well.
