The rationale of this study is to confirm and support the clinical safety and performance of any of these products in a real-word population of 100 patients who underwent an endovascular intervention within standard-of-care (SOC) of the infra-popliteal vessels, using at least one of the products (named above) from Cordis US Corp.


Peripheral artery disease can be a severe and complex condition that is still a challenge for both surgical and endovascular therapies (1,2). Arterial disease is known to be located predominantly in the superficial femoral artery in patients with claudication and in the below-the-knee (BTK) region in patients with critical limb ischemia (CLI). Especially in patients with diabetes (3-5), -where arterial disease is commonly characterized by long, multilevel disease involving all infrapopliteal vessels-the risk of peripheral artery disease is significantly higher and tends to be more aggressive than in patients without diabetes.

Infrapopliteal arterial occlusive disease afflicts numerous patients with pain at rest, ischemic ulceration, or gangrene (6-7). Critical limb ischemia (CLI) mainly results from this disease. In general, patients suffering from CLI have many comorbidities, such as diabetes mellitus and end-stage renal disease, and often have high morbidity, mortality, and consumption of health care and social care resources (6). Therefore, effectual management is urgently required for patients with CLI.

With the rapid improvements in endovascular instruments and experience of physicians, endovascular therapy has become a major option for the revascularization of infrapopliteal occlusive arteries. Percutaneous transluminal angioplasty (PTA) is the most commonly used endovascular therapy for this disease, especially during the initial onset of CLI. Currently, PTA is considered an effective treatment because of its minimal invasiveness, shortened hospitalization time, and acceptable patency rate (8-9). In recent years, several studies have assessed the safety and efficacy of PTA.

In this regard, the purpose of the current post market clinical follow-up (PMCF) trial is to assess the safety and efficacy of different CE-marked medical devices from Cordis (SABER OTW PTA Dilatation Catheter, SABERX PTA Dilatation Catheter, and Powerflex Pro PTA Catheter) used in the infrapopliteal vessels BTK, when used as intended by the manufacturer (i.e., adhering to the Instruction for Use - IFU). The devices under investigation in the current study are the SABER OTW PTA Dilatation Catheter, SABERX PTA Dilatation Catheter, and Powerflex Pro PTA Catheter, which are described in detail in section 3.1.

Also, data will be collected which may also include acute outcomes for the additional supportive devices listed below in detail in section 4. that may have been used during peripheral angioplasty procedure. However, these devices are not a part of the study devices and would not affect the inclusion criteria for study. The additional devices include the Cordis guidewires (Emerald, ATW, Stablizer, Storq, SV 0.018", Wizdom), Cordis guiding catheters (Adroit, Vista Brite Tip), Cordis diagnostic catheters (Super Torque, Super Torque MB, Super Torque Plus, Infiniti 4F/5F/6F, Tempo 4F, Tempo Aqua, High Flow, Pigtail Straightener), Cordis vascular access devices (Avanti+, Brite Tip, Vista Brite IG, vessel dilator), Cordis vascular closure devices (MynxGrip and Mynx Control) and Cordis OUTBACK CTO catheters which may be used during peripheral angioplasty procedures.
