Test device to make dialysis fistulas easier to stick safely
Part of Blood & lymphatic, Kidney & urinary clinical trials.
This trial tests a small implant device that can make dialysis fistulas easier to access with needles when normal needle access is too difficult or risky. It may help reduce painful failed attempts and needle-related complications for people with certain types of fistulas.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have an arteriovenous fistula (AVF) in your arm that is hard to use for repeated dialysis needle sticking, or your clinic can’t reliably cannulate it safely
- A recent ultrasound (within 8 weeks) shows the “stick” area is more than 6 mm deep from the skin, OR your unit confirms repeated sticking isn’t achievable
- Your surgeon expects this device to work at least as well as other methods that make access easier or safer
- Your AVF type is one of these: radio-cephalic, brachio-cephalic, or transposed brachio-basilic
- Your ultrasound (within 8 weeks) must also meet size limits: depth is 15 mm or less at the stick zones, and vein diameter is at least 4 mm in both zones
- You must be able to consent, have at least 2 dialysis treatments per week, and have no major skin infection/allergy or serious infections at the implant site

This trial compares three types of surgical connections (fistulas) between an artery and a vein in the arm, used for dialysis. It looks at which type works best for people with advanced kidney disease who need a new access point for dialysis.
This trial tests a special wrap placed around a new arm access point for dialysis (called an AV fistula) to see if it helps the access stay healthy and work better. It is for people who need a new AV fistula for kidney dialysis.
This trial tests a new device called the Velocity pAVF System that creates a connection between a vein and artery in your arm for hemodialysis. If you need dialysis now or within the next 6 months, this could be a new option for you.
This study tests whether a special ultrasound implant (EchoMark) helps a new dialysis fistula mature properly. It involves people with advanced kidney disease who are starting or already on dialysis and are having a fistula created in the upper arm.
This study tests a new device that may make it easier and more reliable to place needles into your dialysis access (the fistula or graft in your arm). It could help improve your dialysis sessions and comfort.
This study compares two ways to create a dialysis access point in your arm: one is a standard surgery, the other uses a less invasive needle-based technique. The goal is to see which method works better, costs less, and has fewer complications.
