Evaluation of Efficacy and Safety of the FlexStent Self-Expanding Stent System

2014-07-23 21:10:23 | BioPortfolio


Purpose of this registry is to determine the efficacy and safety of the self-expanding, extra flexible FlexStent in patient with superficial femor/popliteal artery disease.

The stent has been developed to cope with the extreme requirements of the femoral artery/knee artery and is approved for usage at humans (EC-certified). It is designed to treat narrows of the femoral- and knee artery.

100 patients at 5 German hospital shall be enrolled. After stent implantation follow-up visits at 6 and 12 month take place.


Peripheral arterial disease (PAD) represents a major challenge to physicians in treating the Superficial Femoral (SFA) and Popliteal arteries. These arteries represent a harsh environment for any endovascular device. This disease is characterized by long occlusions with relatively low flow and with the vessels exposed to enormous mechanical stress. During flexing of the knee, the SFA/Popliteal arteries can bend, rotate, elongate and compress dramatically. An ideal stent designed for use in the SFA/Popliteal arteries would offer great ranges of movement while adequately supporting the arteries.

The FlexStent® stent provides a great range of motions for a highly flexible femoral artery while adequately supporting the vessel. The intended use for the FlexStent® stent is for the treatment of symptomatic femoropopliteal disease, primarily for atherosclerotic de novo native superficial femoral artery lesions.

The intent of this clinical registry is to demonstrate the efficacy and safety of the FlexStent® stent in patients with superficial femoral/ popliteal artery disease.

Hypothesis: the FlexStent® will be safe and efficacious in treating SFA/popliteal artery diseases.

Primary object: evaluation of efficacy of the FlexStent® measured by the in-stent restenosis using DUS following treatment, 6 and 12 MFU visits.

The nervous system outside of the brain and spinal cord. The peripheral nervous system has autonomic and somatic divisions. The autonomic nervous system includes the enteric, parasympathetic, and sympathetic subdivisions. The somatic nervous system includes the cranial and spinal nerves and their ganglia and the peripheral sensory receptors.

Drugs that act principally at one or more sites within the peripheral neuroeffector systems, the autonomic system, and motor nerve-skeletal system. (From Smith and Reynard, Textbook of Pharmacology, 1991, p75)
