1. A medical device comprised of:

  • an expandable stent which takes the form of a hollow tubular member having proximal and distal portions and a longitudinal axis;

    a first bridge member which takes the form of a sinusoidal element having proximal and distal ends, said proximal end of said first bridge member coupled to and extending distally from the distal portion of said expandable stent in a direction substantially parallel to the longitudinal axis of said expandable stent;

    a second bridge member which takes the form of a sinusoidal element having proximal and distal ends, said proximal end of said second bridge member coupled to and extending distally from the distal portion of said expandable stent in a direction substantially parallel to the longitudinal axis of said expandable stent;

    a first self-expanding aneurysm cover formed of a shape-memory sheet initially folded along a plurality of pleats, said first aneurysm cover coupled to and extending from the distal end of said first bridge member and upon expansion becoming planar and lying in a plane substantially perpendicular to the longitudinal axis of said expandable stent; and

    ,a second self-expanding aneurysm cover formed of a shape-memory sheet initially folded along a plurality of pleats, said second aneurysm cover coupled to and extending from the distal end of said second bridge member and upon expansion becoming planar and lying in a plane substantially perpendicular to the longitudinal axis of said expandable stent.
