APPARATUS AND METHOD FOR MANUFACTURING A SINGLE WIRE STENT

摘要

A mandrel (50) for manufacturing a stent from a single wire (30) includes a cylindrical member having a plurality of pins (62) at a proximal end region, a plurality of pins (64) at a distal end region, and a plurality of indentations (68) between the proximal pins and the distal pins. These indentations form a helical pattern on the outer surface of the cylindrical member. The single wire is wrapped around every proximal pin and distal pin on the mandrel by following the indentations in the mandrel. The single wire is slid through the indentation under any crossing section of wire and over the next crossing section of wire in an under-over pattern.
