Stent Graft Delivery System for Accurate Deployment

A delivery system for deploying a stent graft in a body vessel, comprising:

• a wire lumen slidably positionable about a guide wire;
• a support stent having a proximal end and a distal end slidably positioned about the wire lumen and 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 compressed delivery configuration;
• an anchor stent having a proximal end and a distal end slidably positioned about the inner sheath and deployable from a compressed delivery configuration to a deployed configuration;
• an outer sheath retractably positioned about the anchor stent with the anchor stent in the insertion configuration;
• and
• a handle operatively coupled to each of the inner sheath and the outer sheath.

A delivery system for deploying an endoluminal prosthesis within a body lumen at a target location, comprising:

• a delivery sheath having a proximal end and a distal end and configured to retain the prosthesis within the delivery system in an unexpanded configuration at the delivery sheath distal end;
• a support member having a proximal end and a distal end positioned at least partially within the delivery sheath, where the proximal end of the support member is adjacent to the distal end of the prosthesis;
• and
• a handle configured to impart relative movement to at least one of the delivery sheath and the support member.

A delivery system comprising:

• a shaft defining a guide wire passage;
• a support member having a proximal end and a distal end movably coupled to the shaft, and configured to advance in a proximal direction along the shaft;
• and
• a tubular delivery sheath configured to at least partially surround the support member and to retract in a distal direction along the shaft.

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 compressed 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 insertion 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;
• and
• a capture mechanism operatively coupled to the proximal end of the anchor stent, the capture mechanism initially configured to retain the proximal end of the stent in a delivery configuration, the capture mechanism actuatable to release the proximal end of the anchor stent.
