The Challenge

Humans are both living longer and becoming more vulnerable to many health conditions. Vascular stent demand is increasing due to a large number of people with underlying health issues, such as obesity, diabetes, and other conditions that lead to peripheral arterial disease. For coronary intervention, the use of stents has increasingly replaced bypass surgery. Traditional stents straighten arteries and disturb blood flow, creating shear stress that can damage the tissue. This can complicate the healing process after surgery and lead to stent failure.

Innovation Details

The BioMimics 3D Swirling Flow® Stent is self-expanding and has a unique 3D geometry that gives it a slight shape, mimicking the natural shape and geometry of the human vascular system. This results in stents that are more flexible, more kink-resistant, and more fracture-resistant than straight stents. They also impart the swirling flow of blood through the stent, which has been shown to reduce restenosis. The stent also improves biomechanical compatibility and reduces vascular irritation and injury.

Biological Model

The body’s natural defence against the propagation of vascular disease is to generate smooth swirling flow through the arteries, particularly at arterial junctions. This is achieved by the gentle helical geometry of the arterial system. Natural swirling flow eliminates zones of high and low wall shear, cross-mixes nutrients to ensure optimum supply to the vessel wall and sweeps areas of potential stagnant flow. Additionally, the correct level of stable flow against the artery wall activates important defensive genes, which further prevent disease proliferation.
