| 摘要 |
<p>This invention is a dual supported intraluminal graft comprising a biocompatible flexible layer (16) sandwiched between two structural support layers (18, 20). The preferred embodiment comprises a first structural support (18), such as a stent, which is concentrically retained within a tubular shaped PFTE graft (16) which is concentrically retained within a second structural support (20), such as a stent. The ends of the PFTE graft may be folded back onto the outer surface of the second structural support thereby forming flaps (30, 32). Upon radial expansion of the preferred embodiment, the stent/graft/stent assembly forms inseparable layers.</p> |
