Who this study is looking for
In plain language, from the study's own rules. The study team confirms the full details with you — this isn't a final yes or no.

- •Can sign written consent before any study-only procedures and will follow all required visits
- •Have kidney failure needing an upper arm, “autologous” (using the person’s own vein) arteriovenous fistula creation for hemodialysis (not transposed)
- •Are currently on dialysis using a central venous catheter or may need dialysis soon (eGFR <10)
- •Have vein and artery size on mapping that are at least 2.5 mm (at the antecubital fossa for the vein; per mapping for the artery)
🚫 You may not be able to join if…
- •Have CKD Stage 1–4, or do not need upper arm autologous arteriovenous fistula creation for hemodialysis access
- •Have a history of Steal Syndrome
- •Are immunocompromised or immunosuppressed
- •Have had three previous failed AV fistulas for hemodialysis access
- •Have an existing fistula or graft; or plan surgery within 60 days, have active infection (or infection in the 30 days before device placement), active cancer, a bleeding disorder/thrombocytopenia (platelets <50,000), high clotting tendency or certain recurrent DVT history, known/suspected device allergy, expected conversion to peritoneal dialysis or transplant within 6 months, or are pregnant/planning pregnancy/breastfeeding

What you need to know before you apply
What is this study testing?+
This is a prospective, multi-center, two-arm, randomized trial to quantify the performance of the EchoMark®/EchoSure® System for AVF diagnostic ultrasound when used under a protocol of biweekly use for assessing fistula maturation and reducing time to Clinical Maturation.
Is it safe? Who makes sure of that?+
This is a research study. Every study is reviewed and monitored by an independent ethics board (called an IRB) whose job is to protect participants, and care is overseen by licensed medical staff. You'll be told the known risks before you agree to anything, and you can stop at any time.
Will I get a placebo instead of the real treatment?+
Some studies compare a treatment against a placebo (an inactive version), and some don't. If this one does, the study team will explain your chances of receiving the active treatment before you decide. Nothing is hidden from you.
Do I have to stop taking my current medications?+
It depends on the study. Some let you stay on your current medications and some ask you to adjust them. Never stop a medication on your own — the study team will review everything with you first.
Does it cost anything? Will I be paid?+
Study-related care is provided at no cost to you. Some studies also pay for your time; the coordinator can tell you if this one does. You should never be asked to pay to take part.
Do I need insurance? Will anyone ask about my immigration status?+
No. You do not need health insurance to take part in a research study, and you will not be asked about your immigration status to join. Taking part is about whether you're a medical fit for the study.
What if English isn't my first language?+
You have the right to understand everything before you agree. Study sites can often provide materials or an interpreter in your language — you can ask the coordinator for one.
Is my information private?+
Yes. Your health information is only shared with the study sites you choose to be contacted by, and only to help match and enroll you. It is never sold, and you can ask us to delete it at any time.
Some requirements (like specific lab values or timing) are confirmed directly by the study team, not by us.
