  • Stent
    Publication number: 20030083734
    Abstract: A stent for treating vascular stenoses. The stent is insertable into regions of arterial vascular systems close to the ostium. The stent comprises a tubular expandable element made of a mesh fabric which is insertable into the inlet or an outlet of a vessel. The proximal end of the stent is expandable to a trumpet-shaped structure.
