Abstract

A radially-expandable stent for insertion into a lumen is described. The stent is composed of a radially-expandable support stent and a polymer tubular member co-axially disposed over the support stent. Tubular end sleeves are disposed around the first and second ends of the polymer-surrounded support stent to secure the tubular member and to provide other improvements.
