Spiral Laminar Flow™ – Our Technology

What is SLF™?

Spiral Laminar Flow™ is our technology platform that restores the blood flow pattern through prosthetic grafts to the body’s natural state – spiral flow. Our technology platform is based on a renewed understanding of natural blood flow patterns in the body. Research by Stonebridge and Brophy in 1991 established the prevalence and benefits of spiral flow in the circulatory system but we can also see drawings dating back to Leonardo da Vinci which suggest the spiral flow of blood through the veins and arteries of the heart. Cardiovascular disease is the leading cause of death in westernized countries According to the American Heart Association, almost 60 million Americans have one or more types of cardiovascular disease and despite recent advances in cardiovascular therapies, it still results in more than one million deaths per year. Our research has shown that products with Spiral Laminar Flow™ technology, can improve patency rates and  reduce downstream disease progression. 1.
