Key requirements
Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.
- Ages 30 years and older
- All sexes
- No healthy volunteers
- Adult, Older adult
Who may be able to join
- Symptomatic leg ischemia by Rutherford Classification (category 1, 2, 3, 4 or 5); duration of intermittent claudication (category 1-3) should be at least 3 months;
- One de-novo or restenotic SFA with an occluded length > 5 to < 22 cm;
- Patent popliteal artery on the index side (without > 50% stenotic (re) stenotic lesions) and at least single vessel infrapopliteal runoff (without > 50% stenotic (re) stenotic lesions). However, balloon angioplasty to further improve the blood flow is allowed at the index procedure.
Who cannot join
- Revascularization involving the same limb 30 days prior to the index procedure or a planned revascularization within 30 days after the index procedure;
- Patients having severe stenoses or total occlusions of the iliac artery on the same side must be excluded. However, intervention to restore adequate blood flow during the index procedure (prior to the treatment of the target lesion) is allowed;
- Requiring stent placement in the popliteal artery. For the purpose of this protocol all lesions are to be located at least three centimetres proximal to the superior edge of the patella.

About this study
Official title: A Multi-Center Prospective, Randomized, Two-Arm Clinical Investigation of the Cordis SMARTTM Nitinol Self Expandable Stent Versus Balloon Angioplasty Only for the Treatment of Superficial Femoral Artery Occlusions.
This is a multi-center prospective, randomized, two-arm study evaluating performance of the Cordis SMART™ Nitinol Stent System compared to balloon angioplasty. Patients will be randomized on a 1:1 basis. It is anticipated that a total of 120 patients will be entered into the study.
Objective of the study is: Performance of the Cordis S.M.A.R.T.™ (CONTROL™) Nitinol Stent System for the treatment of superficial femoral artery (SFA) long de novo or restenotic lesions (≥ 70% stenosis or occlusions) in comparison with balloon angioplasty as determined by Binary Restenosis (≥50% restenosis based on a peak systolic velocity ratio ≥ 2.5) at one year as demonstrated by Duplex sonography.
Read the detailed description
The study population will consist of 120 symptomatic peripheral vascular disease patients with SFA occlusions. The disease will consist of symptomatic, de novo or restenotic occlusions (5 - 22 cm) on diagnostic imaging. The occlusions must not extend beyond the proximal popliteal artery. For the purpose of this protocol, no lesion within 3 cm of the upper part of the patella may be treated. At least one calf vessel must be patent. Reference vessel diameter must be >= 4.0 to <= 6.0 mm.
Trial participants who meet all entry criteria, will be randomized to the SMART™ Nitinol Stent or balloon angioplasty.
Patients will be followed for 12 months after the procedure. Study examinations will be done at screening, procedure time, discharge, 1, 6 and 12 months after the study procedure.
This study will be conducted as an investigator initiated multicenter study with 6 study centers in Switzerland. Principal investigators will be Prof. Amann, PD Dr. med T. Pfammatter (University Hospital Zürich) and Prof. I. Baumgartner, Prof. J. Triller (University Hospital Bern).

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing stent and balloon in people with Superficial Femoral Artery Occlusions, run by Cordis US Corp. at 2 sites in Switzerland.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 12 Jun 2009. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in Switzerland. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Binary restenosis by Duplex Ultrasound. (time frame: 1 year). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Jun 2009; AzTrials last refreshed its copy on 7 Nov 2026.
