Efficacy Study of Iliac Stents to Treat TASC A-B-C-D Iliac Artery Lesions

Inclusion Criteria: GENERAL * Patient presenting with a stenotic or occlusive lesion at the iliac arteries suitable for stenting (on indication for primary stenting, based on the discretion of the investigator) * Patient presenting a score from 2 to 5 following Rutherford classification * Patient is willing to comply with specified follow-up evaluations at the specified times for the duration of the study * Patient is \>18 years old * Patient (or their legal representative) understands the nature of the procedure and provides written informed consent, prior to enrolment in the study * Patient is eligible for treatment with the Absolute Pro or Omnilink Elite (Abbott Vascular) ANGIOGRAPHIC * The target lesion is either a modified TASC-II class A, B, C or D lesion with one of the listed specifications: * Type A lesions * Unilateral or bilateral stenoses of the Common Iliac Artery * Unilateral or bilateral single short (≤3 cm) stenosis of the External Iliac Artery * Type B lesions * Unilateral Common Iliac Artery occlusion * Single or multiple stenosis totaling 3-10 cm involving the External Iliac Artery not extending into the Common Femoral Artery * Unilateral External Iliac Artery occlusion not involving the origins of Internal Iliac Artery or Common Iliac Artery * Type C lesions * Bilateral Common Iliac Artery occlusions * Bilateral External Iliac Artery stenoses 3-10 cm long not extending into the Common Femoral Artery * Unilateral External Iliac Artery stenosis extending into the Common Femoral Artery * Unilateral External Iliac Artery occlusion that involves the origins of the Internal Iliac and/or Common Femoral Artery * Heavily calcified unilateral External Iliac Artery occlusion with or without involvement of origins of the Internal Iliac and/or Common Femoral Artery * Type D lesions * Unilateral occlusions of both Common Iliac and External Iliac Artery * Diffuse disease involving the aorta and both iliac arteries requiring treatment * Diffuse multiple stenoses involving the unilateral Common Iliac, External Iliac and Common Femoral Artery * Bilateral occlusions of External Iliac Artery * The target lesion has angiographic evidence of stenosis or restenosis \> 50% or occlusion which can be passed with standard guidewire manipulation * There is angiographic evidence of a patent Common an Deep Femoral Artery Exclusion Criteria: * The target lesion is either a modified TASC-II class B or D lesion with aortic lesion involvement: * Type B lesions * Short (≤3 cm) stenosis of infrarenal aorta * Type D lesions * Infra-renal aortoiliac occlusion * Iliac stenoses in patients with an Abdominal Aortic Aneurysm (AAA) requiring treatment and not amenable to endograft placement or other lesions requiring open aortic or iliac surgery * Presence of aneurysm at the level of the iliac arteries * Previously implanted stent(s) at the same lesion site * Reference segment diameter is not suitable for available stent design * Untreatable lesion located at the distal outflow arteries * Use of alternative therapy (e.g. atherectomy, cutting balloon, laser, radiation therapy) as part of the index procedure * Patients refusing treatment * Patients for whom antiplatelet therapy, anticoagulants or thrombolytic drugs are contraindicated * Patients who exhibit persistent acute intraluminal thrombus of the proposed lesion site * Perforation at the angioplasty site evidenced by extravasation of contrast medium * Patients with a history of prior life-threatening contrast medium reaction * Patients with known hypersensitivity to nickel-titanium * Patients with uncorrected bleeding disorders * Female patient with child bearing potential not taking adequate contraceptives or currently breastfeeding * Life expectancy of less than twelve months * Any planned surgical intervention/procedure within 30 days of the study procedure * Any patient considered to be hemodynamically unstable at onset of procedure * Patient is currently participating in another investigational drug or device study that has not completed the entire follow up period.
