Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of this IIT is to determine the potential improvement and impact of the BioMimics 3D Stent System in the SFA on local vascular function.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The MIMICS FLOW Study is a single-center, single-blind, investigator-initiated, randomized parallel group trial.

The impact of a novel biomimetical stent with a helical curvature provides superior hemodynamic and biomechanical performance and advantages. Additionally, it promotes swirling blood flow, elevating wall sheer strength, which is patency-protective and might impact on vascular functions due to completely different vascular properties through altered blood flow.

The influence of the novel devices and stent-platforms with improved hemodynamic capabilities with respect to vasomotor of the vessel wall, vascular function and vascular compliance can be measured by FMD, arterial stiffness indices and vascular strain analysis.

* Pretreatment with an adequately sized ballon (1:1 ration to nonstenotic vessel diameter)
* usage of Biomimics stent as described in the IFU, especially regarding stent diameters and vessel size

Exclusion Criteria

* Bifurcational lesions of the CFA and lesions including the first 3 cm of the SFA, due to technical aspects of FMD measurement

* Known or suspected active infection at the time of the index procedure, excluding an infection of a lower extremity wound of the target limb
* Known or suspected allergies or contraindications to aspirin, clopidogrel or heparin
* Presence of other hemodynamically significant outflow lesions in the target limb requiring a planned surgical intervention or endovascular procedure within 30 days after the index procedure
