A delivery system for deploying a stent graft at a lesion site is provided. The delivery system comprises a wire lumen and a support stent slidably positioned about the wire lumen. The support stent is expandable from a compressed delivery configuration to an expanded configuration. An inner sheath is retractably positioned about the support stent with the support stent in the delivery configuration. An anchor stent is slidably positioned about the inner sheath. A tubular graft proximal end is coupled to the anchor stent and deployable with the anchor stent from a compressed delivery configuration to a deployed configuration. An outer sheath is retractably positioned about the anchor stent and the graft in the compressed delivery configuration. |
