DRUG-DELIVERY ENDOVASCULAR STENT AND METHOD FOR TREATING RESTENOSIS
摘要:
A radially expandable, endovascular stent designed for placement at a site of vascular injury, for inhibiting restenosis at the site, a method of using, and a method of making the stent. The stent includes a radially expandable body formed of one or more metallic filaments and a liquid-infusible mechanical anchoring layer attached to or formed in outer surface of the filaments. A drug coating in the stent is composed of a substantially polymer-free composition of an anti-restenosis drug, and has a substratum infused in the anchoring layer and a substantially continuous surface stratum of drug that is brought into direct contact with the vessel walls at the vascular site. Thus, the rate of release of the anti-restenosis drug from the surface stratum into said vascular site is determined solely by the composition of said drug coating.
