Abstract
A method and apparatus for forming a covered endoprosthesis employs a conformed polymeric coating about an expandable stent. The expandable stent has an open tubular construction. A first polymeric liner is positioned about an inner surface of the tubular stent and a second polymeric liner is positioned about an outer surface of the tubular stent. The first and second polymeric liners are conformed to the tubular stent and laminated together through the open construction of the stent at a location coextensive with the inner surface of the tubular stent.
