Outcome Measures
Primary Outcomes (4)
Percentage of Patients With Primary Patency
Primary patency was defined as the interval of time from access placement until any intervention designed to maintain or reestablish patency, access thrombosis, or the time of measurement of patency.
6 months, 12 months
Percentage of Patients With Assisted Primary Patency
Assisted primary patency was defined as the interval of time from access placement until access thrombosis or the time of measurement of patency, including intervening manipulations (i.e., surgical or endovascular interventions) designed to maintain the functionality of a patent access.
6 months, 12 months
Percentage of Patients With Secondary Patency
Secondary patency was defined as the interval of time from access placement until access abandonment, thrombosis, or the time of patency measurements including intervening surgical or endovascular interventions designed to reestablish functionality in a thrombosed access.
12 months
Number of Patients With Serious Device or Implant Procedure-related Adverse Events
Serious adverse events were defined as events that required hospitalization ≥24 hours, prolonged an existing hospitalization, resulted in persistent or significant disability or incapacity, were considered life-threatening, or resulted in death.

Eligibility Criteria
You may qualify if:
- years of age or older.
- Male or non-pregnant female.
- Life expectancy 2 years.
- End-stage renal disease requiring an arm vascular prosthesis for dialysis access.
- Ability to understand and provide written informed consent.
- Willing and able to cooperate with follow-up examinations.
- Subject's upper arm can be used for implant (Note: The GVAS device must be implanted in the upper arm only, but the Control group graft can be implanted in the upper or lower arm location.).
- Able to follow a daily aspirin and/or other oral anticoagulation/antiplatelet regimen.
You may not qualify if:
- Potential graft target artery less than 3 mm in diameter determined by any suitable preoperative measure.
- Documented history of drug abuse within six months.
- "Planned" concomitant surgical procedure or previous major surgery within 30 days, excluding vascular access related procedures.
- Currently being treated with another investigational device or drug.
- Known bleeding diathesis or hypercoagulable state.
- Peripheral white blood cell count 1500/mm3 (1.5 K/mm3) or platelet counts 50,000/mm3 (50 K/mm3).
- Degenerative connective tissue disease, e.g., Marfan's and Ehlers Danlos Syndrome. Subjects with Lupus Erythematosus may be included.
- Subjects with known or suspected concomitant bacterial, fungal, viral, or parasitic infection. Subjects with Hepatitis B may be included. Subjects who are HIV + with CD4 count of \<200 are excluded.
- Severe underlying co-morbidity or immediate life-threatening condition.
- Subjects with any condition which, in the opinion of the investigator, could preclude evaluation of response or completion of follow-up or affect subject safety.
- Subjects who are candidates for autologous fistulas.
- Subjects with scheduled renal transplant within the next 12 months.

Limitations and Caveats
Due to slow enrollment and early termination of the study, a shortcoming of this trial, a final conclusion on equivalency between the HeRO Graft and conventional AV graft could not be firmly established.
