Spiral laminar flow is the predominant flow pattern in 97% of patients in observational study

Vascular Flow Technologies has presented data showing that spiral laminar flow is the predominant flow pattern in arteries.

The “Spiral laminar flow in arteries” study is one of a number highlighting the advantages of Spiral Laminar Flow technology being presented at the 42nd Annual VEITH Symposium (17–21 November, New York, USA).

While the existence and benefits of spiral flow in the circulatory system was established by Stonebridge and Brophy in 1991, the current study suggests that spiral laminar flow is the predominant flow pattern in the arteries. Its presence was assessed at 11 arterial sites in 42 volunteers with colour flow Doppler. Its incidence at each of these 11 sites ranged from 81–90%. Analysis on the basis of volunteer rather than examination site showed 41 patients out of the 42 in the cohort (97%) had more arterial sites with spiral laminar flow than without.

Vascular Flow Technologies uses Spiral Laminar Flow technology in its vascular implants to promote longevity and patency of the implant and improve patient outcomes. A helical formation incorporated as a ridge or groove in the implant serves to induce a spiral pattern of blood flow through the implant, replicating the natural spiral laminar flow observed in healthy vessels. The study, led by Graeme Guthrie, suggests that the flow pattern induced by the technology has the potential to replicate natural blood flow in the majority of patients, for cardiovascular diseases at a variety of arterial sites.

Bill Allan, chief executive officer of Vascular Flow Technologies commented: “The results of this observational study are further evidence that Spiral Laminar Flow technology has the potential to reduce the risk of complications post implantation for a wider range of patients.”
