Misago Iliac Study

Inclusion criteria

• 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 Misago (Terumo)
• The target lesion is either a modified TASC-II class A or B 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
• 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

• 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
