What this trial studies

This observational study aims to enhance understanding of the safety and performance of the HeRO Graft System and Super HeRO Adaptor in adults undergoing hemodialysis. Participants will be those who have exhausted all other dialysis access options and are currently using these devices as part of their routine medical care. The study will involve regular clinic visits over two years, with follow-up phone calls to monitor health and dialysis status if clinic visits are missed.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with end-stage renal disease who are currently treated with the HeRO Graft or Super HeRO System.

Not a fit: Patients with a previously placed HeRO or Super HeRO device undergoing revision or replacement, or those with infections related to the implantation site, may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve long-term dialysis access solutions for patients with end-stage renal disease.

How similar studies have performed: While this study focuses on specific devices, similar observational studies have shown promise in understanding the effectiveness of alternative dialysis access methods.
