| 摘要 |
<p>The present invention relates to devices, systems and methods for implanting a radially extendable endoluminal graft. In certain aspects, the devices, systems, and methods of the present invention include a radially expandable endoluminal graft mounted on a delivery tube and having a distal end and a proximal end. A first retention element is also mounted on the delivery tube at or adjacent to the distal end of the expandable endoluminal device, and a second retention element is mounted on the delivery tube at or adjacent to the proximal end of the expandable endoluminal device. Expansion of the first and/or second retention elements reduces or prevents migration of the graft during and immediately after graft deployment.</p> |
