Stent Graft Delivery System for Accurate Deployment
First Claim
1. A delivery system for deploying a stent graft in a body vessel, comprising:
- a wire lumen;
a support stent slidably positioned about the wire lumen and having a proximal end and a distal end, the support stent expandable from a compressed delivery configuration to an expanded configuration;
an inner sheath retractably positioned about the support stent with the support stent in the delivery configuration;
an anchor stent slidably positioned about the inner sheath and having a proximal end and a distal end, the anchor stent deployable from a compressed delivery configuration to a deployed configuration, a tubular graft having a proximal end and a distal end, the graft proximal end coupled to the anchor stent and deployable with the anchor stent from a compressed delivery configuration to a deployed configuration; and
an outer sheath retractably positioned about the anchor stent and the graft in the compressed delivery configuration.

Abstract
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.
