Artio Medical, Inc., a medical device company developing innovative products for the peripheral vascular, neurovascular, and structural heart markets, announced that full results from its first-in-human (FIH) clinical study of the Amplifi Vein Dilation System were presented at the 2021 VEITH Symposium by Surendra Shenoy, MD-PhD, an Associate Professor of Surgery at the Washington University School of Medicine at Barnes-Jewish Hospital in St. Louis, Missouri.
“Data from the first five patients treated with the Amplifi System demonstrated more than a doubling of forearm and upper arm cephalic vein diameters following a mean treatment period of 8.6 days. We were able to successfully create an arteriovenous fistula (AVF) using treated veins in all patients and observed rapid and robust AVF maturation,” commented Dr. Shenoy. “This data is very encouraging and I believe this technology has the potential to offer a much-needed solution for increasing AVF suitability and reducing maturation failure.”
Quickly establishing a reliable, long-lasting vascular access site is critical for end-stage renal disease patients who require lifesaving hemodialysis treatment. Although an AVF is the preferred form of vascular access, many hemodialysis patients are not suitable for an AVF, often due to small vein diameters. For those patients who are suitable, AVF maturation failure rates are high and prior studies have shown a correlation between small vein diameter and fistula failure.¹ The Amplifi Vein Dilation System is designed to stimulate arm vein enlargement prior to AVF creation to make more patients eligible for AVF surgery, reduce the time required for AVF maturation, and increase successful maturation rates.
Dr. Shenoy added, “When physicians create AVFs , we know there are often vein segments with pre-existing problems, but we don’t currently have adequate tools to identify these segments, which contributes to the high rate of AVF maturation failure.
