Abstract
A stent-graft delivery system and methods for use are provided for use in treating aneurysms occurring in single and bifurcated lumen hollow-body organs or vessels and for treating arterio-venous fistulas. A graft delivery component provides a clinician with complete control over the location of a graft at any time prior to implantation of stents, even when the graft is deployed from its introducer catheter. The graft delivery component includes a plurality of radially expandable fingers that releasably engage the graft, while the stent delivery component includes a small diameter introducer catheter and permits a wide range of conventional stent designs to be used to permanently fix the graft in position.
