Absence of reintervention is defined as: The absence of unanticipated additional procedures related to the device, procedure, or withdrawal of the delivery system

Primary Safety Endpoint as measured by a composite of the absence of aortic rupture, lesion-related mortality, disabling stroke, permanent paraplegia, permanent paraparesis, and new onset renal failure requiring permanent dialysis.30 Days

The primary safety endpoint is a composite of the following events through 30 days post endovascular procedure:

* Aortic rupture

* Lesion-related mortality

* Disabling Stroke

* Permanent paraplegia

* Permanent paraparesis
