ABSTRACT:
An intraluminal prosthesis for intraluminal repair of body conduits, especially aortic aneurysms, is disclosed. The prosthesis includes a generally tubular, flexible graft (20) having a proximal open end (30) and at least one distal open end (31) terminating in a hem (33). A stent (21) can be disposed within the proximal open end (30) and is adapted to be attached to the body conduit (1). The hem (33) is inverted within the graft so that it is disposed as a cuff (34) within the graft. The hem (33) is arranged so that upon withdrawing the distal open end (31) from inside the cuff (34), the cuff will unfold and follow the distal open end to expose it to receive another stent for attachment to the body conduit (12) for intraluminal implantation of the graft. Preferably the hem is folded a second time within the cuff to form a second cuff (35) within the graft. The stents are preferably formed of a plexus of wires adapted to expand from a first narrow diameter to a second diameter to engage the body conduit. Also disclosed is a method of intraluminal implantation of the graft.
