Prospective, nonrandomized, single-arm, single-center, open-label, initial safety study in subjects requiring hemodialysis. Subjects will be followed with physical evaluation and ultrasound vessel imaging at days 15, 29, 57 and weeks 12, 26. Extended follow up on patent conduits only at weeks 52 and 104.
Twenty (20) patients with end-stage kidney disease (ESKD), who are poor candidates for an autogenous fistula creation and either on hemodialysis or expected to start hemodialysis within 12 weeks of study conduit implantation will be implanted with a TRUE AVC as an arteriovenous conduit in the upper extremity. Study subjects will be evaluated for implant safety and patency at 26 weeks. Subjects will be followed with physical evaluation and ultrasound vessel imaging at days 15, 29, 57 and weeks 12, 26. Extended follow up on patent conduits only at weeks 52 and 104.

Inclusion Criteria:
Patients with end stage kidney disease (ESKD) who are poor candidates for creation of a simple autogenous AV fistula (without requiring transposition) and therefore need placement of an AV access in the upper extremity to start or maintain hemodialysis therapy.
Either on hemodialysis or expected to start hemodialysis within 12 weeks of study conduit implantation.
Patients between 18 and 75 years old, inclusive.
Verify adequate arterial flow and venous runoff using duplex ultrasound and venogram. Ensure outflow vein is at least 5 mm in diameter with good compliance.
Hemoglobin ≥8g/dL and platelet count ≥100,000/mm3 prior to implant.
Other hematological and biochemical parameters within a range consistent with ESKD and acceptable for the administration of regional or general anesthesia prior to implant.
Adequate liver function, defined as serum bilirubin ≤1.5 mg/dL; GGT, AST, ALT, and alkaline phosphatase ≤2x upper limit of normal or INR ≤ 1.5 prior to implant.
Life expectancy of at least 1 year.
Negative COVID-19 test within 3 days prior and negative for symptoms within 14 days prior to implant.
Female subjects must be either:
i. Must have a negative urine blood pregnancy test at Screening, and ii. Must agree to use at least one form of the following birth control methods for the duration of the study:
1. Established use of oral, injectable or implanted hormonal methods of contraception 2. Placement of an intrauterine device or intrauterine system 3. Barrier methods of contraception: condom or occlusive cap (diaphragm or cervical/vault caps) with spermicidal foam/ gel/ film/ cream/ suppository 11. Able to communicate meaningfully with investigative staff and able to comply with entire study procedures.
12. Willing and competent to give written informed consent
Exclusion Criteria:
self-report of gender identity
