Study summary

The goal of this observational study is to increase the understanding of the safety and performance of Merit Medical's HeRO Graft System (HeRO) and Super HeRO Adaptor and Support Seal System (Super HeRO) devices. This study includes adults that are being treated with one of these devices as part of their regular medical care for maintaining long-term dialysis access when all other dialysis access options have failed. If participants in the study are not seen for a standard of care clinic visit during the 4 visit timepoints over 2 years, the participant will be followed by phone to check their current health and dialysis status.

Study population

End-stage renal disease patients on hemodialysis who have exhausted all other access options.

Eligibility criteria

Key Inclusion Criteria:

  • Subject provides written
  • Subject is ≥ 18 years
  • Subject is end-stage renal disease patient on hemodialysis.
  • Subject is treated with HeRO Graft or Super HeRO System in accordance with device instructions for use (IFU)

Key Exclusion Criteria:

  • Subject has a previously placed HeRO or Super HeRO device that is undergoing revision or replacement
  • Subject has a topical or subcutaneous infection associated with the implantation site
  • Subject has known or suspected systemic infection, bacteremia or septicemia
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Jul 2025 (actual). Primary completion is estimated for Jun 2027, 23 months after the start.

Of 150 observational studies under Kidney Failure, Chronic, half reached primary completion within 29 months of starting (the median), counting those still running; a quarter within 11 and three quarters within 62. This study's planned 23 months is below that.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jun 1, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
