Apparatus and method for deploying an aortic arch graft
First Claim

1. A graft assembly, comprising:
- a) a tubular graft having a central lumen extending to and meeting with first and second open ends;
b) at least one string removably attached to the graft proximate the first open end; and
c) at least one stylet having a length between distal and proximal ends, wherein the stylet is provided with an attachment portion at its distal end that captures the string adjacent to the first open end of the craft so that the proximal end of the stylet is manipulatable to move the distal end of the stylet and the graft connected to each other by the string to a treatment zone in a vasculature, and wherein the stylet and the string are detachable from the graft.

Abstract
A method and apparatus for engrafting a blood vessel comprising a thin walled graft assembly with radio opaque marker, a guide wire, a guided cartheter with proximal side openings, and a set of open end stylets. The method and apparatus provides for transarterial guidance and deployment of a graft assembly for non-surgical exclusion of aortic aneurysms. The method and apparatus provides for guiding a graft assembly over the aortic arch to the ascending aorta and for guiding a graft assembly in the thoracoabdominal arterial tree.

9. An apparatus for positioning a graft at a treatment zone in a vasculature, the apparatus comprising:
-
a) a tubular graft having a central lumen extending to and meeting with first and second open ends; b) at least one first string removably attached to the graft proximate the first open end and at least one second string removable attached to the graft proximate the second open end; c) at least one guide wire having a length sufficient to extend through the vasculature and past the treatment zone, wherein the guide wire has a proximal end manipulatable from a first location outside the vasculature and a distal end manipulatable from a second location outside the vasculater, the first and second locations outside the vasculature being on opposite sides of the treatment zone and wherein the guide wire has a first attachment portion at its proximal end that captures the first string adjacent to the first open end of the graft; d) at least one stylet having a length between distal and proximal ends, wherein the stylet is provided with a second attachment portion at its distal end that captures the second string adjacent to the second open end of the graft so that the proximal end of the stylet is manipulatable to move the distal end of the stylet and the second open end of the craft connected to each other by the second string to the treatment zone in the vasculature as the distal end of the guide wire is manipulatable to move the proximal end of the guide wire and the first open end of the craft connected to each other by the first string to the treatment zone, and wherein the guide wire and the first string are detachable from the graft and the stylet and the second string are detachable from the graft. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 26, 27)

18. A method for engrafting a blood vessel to repair an aortic aneurysm comprising the steps of:
-
a) preloading a graft within a sheath introducer; b) removably attaching a plurality of strings and a plurality of stylets to the graft; c) inserting arterial sheaths into the brachiocephalic and femoral arteries percutaneously; d) passing guide wires into the brachiocephalic arteries under an image amplifier; e) retrieving first ends of said guide wires from the groin and attaching the plurality of strings to the guide wires; f) pulling each guide wire from the femoral artery to the brachiocephalic artery; g) withdrawing the guide wire from the brachiocephalic arteries; h) removing the strings from the guide wires; i) inserting the sheath introducer into the femoral artery; j) guiding the graft to the location of the aortic aneurysm by pulling the strings and pushing the stylets; k) holding the strings and stylets in position while removing the sheath introducer; l) passing a preloaded stent catheter over said guide wires into a lumen of the graft; m) deploying a stent into the graft; n) withdrawing the stent catheter from the blood vessel and deploying another stent within the graft by the method of step m; and o) removing the guide wires, the stent catheter, the strings, the stylets, and the arterial sheathes from the vessel and attending to the entry sites. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25)
