Abstract
Abstract A intraluminal stent and graft includes a stent made of a continuous helix of zig-zag wire and loops which connect adjacent apices of the wire. The stent is compressible and self-expandable substantially to a pre-compressed configuration. The device also includes a graft secured to the stent and made of a suitable biocompatible material.
