Abstract
A cylindrical shaped stent to prevent arterial acute closure and subsequent restenosis formed of longitudinal wires of biocompatible metal. The wires are welded together in pairs at alternate ends with each pair of wires bent into a V-section. The wires are all formed into a cylinder welded closed to form the stent. The stent is compressed and loaded into an outer catheter by a special tool. The stent is positioned and released for self expansion in situ by an inner catheter. A guide wire through both assists in threading the catheters through blood vessels.
