A tubular prosthesis device (10) for use within the body. The device (10) includes, a metal filament (11) material formed of metal outer member (4) having an exposed outer surface and a core (8) within the extended outer member formed of a different metal than the outer member. The core (8) is secured within and substantially enclosed by the outer member (10). The device can be reduced to a small size for introduction into the body lumen and expandable to a sufficiently large size to engage the wall of the body lumen.
