- Poor aortoiliac or common femoral "inflow" (i.e. angiographically defined >50% stenosis of the iliac or common femoral artery) must be successfully treated prior to treatment of the target lesion. This can be done just prior to treatment of the target lesion. Successful treatment is defined as <30% stenosis after either PTA or stenting of the inflow lesion. After successful treatment of the inflow lesion, the subject will be included in the study following sheath placement distal to the treated lesion.
