AORTIC STENT GRAFT, DELIVERY SYSTEM AND METHOD

摘要

Embodiments of the present invention provide an aortic stent graft configured for placement in the aortic arch and a delivery system to enable endovascular delivery of the aortic stent graft. The configuration of the aortic arch presents particular problems for endovascular repair. The aortic stent graft comprises a tubular main graft body, and three tubular graft branches. The tubular main graft body is configured to extend from within a portion of the ascending aorta to within a portion the descending aorta. The three tubular graft branches extend from the tubular main graft body to align with and extend into three aortic branch vessels extending from the aortic arch. The aortic stent graft and delivery system allows positioning of the tubular main body in the aortic arch and each one of the three tubular graft branches into one aortic branch vessel via an endovascular procedure, with the stent graft delivered via a trans-apical route, anterograde, via a left lateral thoracotomy, through the left ventricle of the heart.
