Post Market Study for VasQ, an External Support Implant for Arteriovenous Fistula

This study is following patients who receive a small surgical implant called VasQ — a device that wraps around the outside of a newly created arteriovenous (AV) fistula (a surgically made connection between an artery and vein in the arm used for dialysis). The goal is to see how well the fistula functions over time when supported by this device. **You may be eligible if...** - You are 18–80 years old - You need dialysis and are having a new AV fistula created in your wrist or upper arm (radiocephalic or brachiocephalic fistula) - You are male, or a female who is not pregnant - You are able and willing to attend follow-up visits over 12 months **You may NOT be eligible if...** - The surgery is a revision of an existing fistula (not a brand-new one) - The target vein has significant narrowing (50% or more) that would affect outcomes Talk to your doctor to see if this trial is right for you.
