Abstract
Abstract Methods and apparatus for implanting a radially expandable stent and separate film within a body vessel. The film is separate from the stent and releasably retained thereon during advancement of the stent to the body vessel. Some methods according to the present invention include steps of providing a collapsed, radially expandable stent; providing a film that is separate from the stent, the film being provided in sheet form; wrapping the film around at least a portion of the stent; and releasably securing the film around the stent with at least one suture or by releasably attaching the first end of the film to a second end of the film. The apparatus according to the present invention include a collapsed, radially expandable stent and a film separate from the stent. The film is releasably attached around the stent by a suture or by releasably attaching the first end of the film to the second end of the film.
