Stent graft delivery system with access conduit

A delivery system for deployment of a stent graft, comprising:

• a delivery catheter having an elongate tubular access conduit and an outer sheath;
• and
• a stent graft radially constrained by the outer sheath and positioned relative to the delivery catheter such that a distal end of the elongate tubular access conduit is disposed between an outer surface of the stent graft and an inner surface of the outer sheath,
• wherein the distal end of the access conduit is positioned between a distal end of a proximal overlap section, which extends distally from a proximal end of the stent graft, and a proximal end of a distal seal section, which extends proximally from a distal end of the stent graft, and
• wherein the proximal overlap section is configured to couple and seal an inner surface of an inner lumen of an endoluminal prosthesis, and
• wherein a distal port of the access conduit is configured to be in fluid communication with an interior volume of an enlarged portion of a patient's vessel.

A delivery system for deployment of a stent graft, comprising:

• a delivery catheter including:
• an elongate shaft having a proximal section and a distal section,
• a stent graft restraint that is configured to at least partially and releasably secure a stent graft in fixed relation to the elongate shaft, and
• an elongate tubular access conduit extending from the proximal section to the distal section of the elongate shaft, the access conduit further including a proximal end, a distal end, a distal port, a proximal port and an inner lumen extending between and in fluid communication with the distal port and proximal port;
• and
• a stent graft releasably secured to the distal section of the elongate shaft by the stent graft restraint with the stent graft in a radially constrained state, the stent graft comprising a proximal end, a distal end, and at least one inner lumen extending from the proximal end to the distal end,
• wherein the stent graft restraint comprises an axially slidable outer sheath disposed over the stent graft and elongate shaft with the outer sheath being configured to radially constrain the stent graft and with the distal end of the access conduit being disposed between an outer surface of the stent graft and an inner surface of the outer sheath when the outer sheath is disposed in a distal-most axial position.

A system for treating an aneurysm, comprising:

• a delivery system for deployment of a stent graft, comprising:
• a delivery catheter including:
• an elongate shaft having a proximal section and a distal section,
• a stent graft restraint that is configured to at least partially and releasably secure a stent graft in fixed relation to the elongate shaft, and
• an elongate tubular access conduit extending from the proximal section to the distal section of the elongate shaft, the access conduit further including a proximal end, a distal end, a distal port, a proximal port and an inner lumen extending between and in fluid communication with the distal port and proximal port;
• and
• a stent graft releasably secured to the distal section of the elongate shaft by the stent graft restraint with the stent graft in a radially constrained state, the stent graft comprising a proximal end, a distal end, and at least one inner lumen extending from the proximal end to the distal end;
• and
• a thrombogenic agent for delivery through the inner lumen and from the distal port of the access conduit,
• wherein the stent graft restraint comprises an axially slidable outer sheath disposed over the stent graft and elongate shaft with the outer sheath being configured to radially constrain the stent graft and with the distal end of the access conduit being disposed between an outer surface of the stent graft and an inner surface of the outer sheath when the outer sheath is disposed in a distal-most axial position.
