Abstract

An aortic arch graft includes a generally cylindrical member formed from a plurality of struts having a proximal end and a distal end and a longitudinally extending lumen. The proximal end is configured for deployment within the ascending aorta and the distal end configured for deployment in the descending thoracic aorta. The aortic arch graft includes a graft material having an opening disposed between the proximal end and distal end with a plurality of radiopaque markers disposed around a periphery of the opening. The opening within the graft material allows blood flow transverse to the longitudinal lumen of the generally cylindrical member.

Claims

1 - 10 . (canceled) 
     
     
         11 . A method for deploying a endovascular graft with an anchoring stent, the method comprising:
 inserting an introducer sheath in an artery;   inserting a first delivery sheath through the introducer sheath, the first delivery sheath containing a valve member;
 wherein the valve member includes:
 an elongate tubular portion having a proximal end and a distal end defining a length therebetween, the elongate tubular portion having at least one aperture disposed in a sidewall at a location between the proximal and distal ends, and 
 a plurality of leaflets, and 
 
   deploying the valve member out of the delivery;   removing the first delivery sheath;   inserting a second delivery sheath through the introducer sheath, the second delivery sheath containing at least one endovascular graft and at least one coronary stent;
 wherein the at least one endovascular graft includes:
 a first endovascular graft having a proximal end and a distal end defining a length therebetween and an opening at the proximal and distal ends; 
 
   deploying the first endovascular graft out of the second delivery sheath;   coupling the first endovascular graft coupled to the valve member;   deploying the at least one coronary stent out of the second delivery sheath and through the aperture in the valve member.   
     
     
         12 . The method of  claim 11 , further comprising deploying a second endovascular graft out of the second delivery sheath, wherein:
 the second endovascular graft includes a proximal end and a distal end defining a length therebetween and an opening at the proximal and distal ends, the second endovascular graft having a bifurcated lumen including a main lumen extending the length of the graft and a branched lumen longitudinally offset to a side of the main lumen; and   coupling the second endovascular graft to the first endovascular graft.   
     
     
         13 . The method of  claim 12 , further comprising deploying at least one anchoring stent from the second endovascular graft,
 wherein the at least one anchoring stent having a proximal end and a distal end defining a length therebetween and an opening at the proximal and distal ends; and   coupling the at least one anchoring stent to the second endovascular graft with the proximal end of the at least one anchoring stent disposed within the main lumen and between the proximal and distal ends of the second endovascular graft, and the distal end of the at least one anchoring stent extending outward from the second endovascular graft at a location between the proximal and distal ends of the second endovascular graft.   
     
     
         14 . The method of  claim 13 , wherein the at least one anchoring stent is deployed from within a central lumen of the second endovascular graft. 
     
     
         15 . The method of  claim 13 , wherein the at least one anchoring stent is deployed in a distal-proximal fashion. 
     
     
         16 . The method of  claim 13 , wherein the at least one anchoring stent is deployed in a proximal-distal fashion. 
     
     
         17 . The method of  claim 11 , wherein at least one delivery sheath is inserted through the introducer sheath in a retrograde fashion. 
     
     
         18 . The method of  claim 13 , wherein the at least one anchoring stent is a self-expanding anchoring stent. 
     
     
         19 . The method of  claim 13 , wherein the at least one anchoring stent is coupled to the second endovascular graft at an opening disposed on the second endovascular graft. 
     
     
         20 . The method of  claim 13 , wherein the at least one anchoring stent is formed with a bend of up to 90 degrees. 
     
     
         21 . The method of  claim 11 , wherein the artery is the femoral, iliac, axillary, carotid, or brachiocephalic artery. 
     
     
         22 . The method of  claim 13 , wherein the second endovascular graft and the at least one anchoring stent are crimped within the delivery sheath. 
     
     
         23 . The method of  claim 13 , wherein the at least one anchoring stent comprises a cross-section, the cross-section including a first diameter greater than a second diameter of the artery in which the anchoring stent is disposed.
