Method for Deployment of a Stent Graft
First Claim
1. A method for deploying a stent graft in a body vessel, comprising:
- providing a delivery device having a support stent slidably positioned about a 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 deployable from a compressed delivery configuration to a deployed configuration;
retracting the outer sheath to expand the anchor stent from the delivery configuration to an expanded configuration;
deploying the anchor stent in the body vessel; and
retracting the inner sheath to expand the support stent from the compressed insertion configuration to an expanded configuration.

Abstract
The method includes providing a delivery device. The delivery device comprises a support stent, an inner sheath, and an outer sheath. The support stent is slidably positioned about a wire lumen. The support stent has a proximal end and a distal end, and is expandable from a compressed delivery configuration to an expanded configuration. The inner sheath is retractably positioned about the support stent with the support stent in the delivery configuration. The anchor stent is slidably positioned about the inner sheath and is deployable from a compressed delivery configuration to a deployed configuration. The outer sheath is retracted to expand the anchor stent from the delivery configuration to an expanded configuration. The anchor stent is deployed in the body vessel. The inner sheath is retracted to expand the support stent from the compressed insertion configuration to an expanded configuration.

13. A method for deploying a stent graft in a body vessel at a target location, comprising:
-
providing a stent graft having a proximal end, a distal end, and a distal ring at the distal end;
providing a delivery device configured to retain the stent graft in a delivery configuration during delivery of the stent graft to the target location, the delivery device having an inner sheath and an outer sheath;
moving the delivery device in at least one of a proximal direction and a distal direction to position the distal ring of the stent graft at a distal anchor location with respect to the target location;
withdrawing the outer sheath of the delivery device to deploy the distal end of the stent graft and the distal ring;
anchoring the distal ring to a vessel wall at the distal location;
withdrawing the inner sheath of the delivery device to deploy the proximal end of the stent graft; and
anchoring the proximal end of the stent graft to the vessel wall at a proximal anchor location. - View Dependent Claims (14, 15, 16, 17, 18, 19)
