Study Details

Study Description

Brief Summary

The proposed clinical study is a prospective, non-randomized, multi-center, single-arm, observational, post-market surveillance (PS) study of the Ellipsys Vascular Access System in subjects eligible for arteriovenous (AV) fistula.

Condition or Disease Intervention/Treatment Phase
  • Device: Ellipsys Vascular Access System
N/A

Detailed Description

The primary objective of this post-market surveillance study is to support the short-term safety of the device and procedure and further assess long-term safety and effectiveness in subjects treated by newly trained providers of the Ellipsys Vascular Access System in the creation of a native AV fistula via percutaneous access in subjects who are on hemodialysis and are medically indicated for the creation of an upper limb anastomosis.

Arms and Interventions

Arm Intervention/Treatment
Experimental: Ellipsys Vascular Access System

The Ellipsys System is indicated for the creation of a proximal radial artery to perforating vein anastomosis via a retrograde venous access approach in patients who have chronic kidney disease requiring dialysis.

Device: Ellipsys Vascular Access System
The Ellipsys System is indicated for the creation of a proximal radial artery to perforating vein anastomosis via a retrograde venous access approach in patients with a minimum vessel diameter of 2.0mm and less than 1.5mm of separation between the artery and vein at the fistula creation site who have chronic kidney disease requiring dialysis.

Outcome Measures

Primary Outcome Measures

  1. Cumulative Patency Through 12 months Post-AVF Creation [12 months post-procedure]

    Freedom from access abandonment from time of access creation

  2. Early Occlusion Rate at 7 days [7 days post-procedure]

    Percent of patients with total occlusion within 7 days of the AVF creation procedure

  3. Study Related Serious Adverse Event (SAE) Rate Through 12 months [12 months post-procedure]

    Rate of serious adverse events through 12 months related to the device, study procedure, or secondary procedure to maintain or re-establish patency.

Secondary Outcome Measures

  1. Primary Patency Through 12 months Post-AVF Creation [12 months post-procedure]

    Freedom from access thrombosis or any intervention designed to facilitate, maintain or re-establish patency measured from time of access creation through 12 months

  2. Assisted Primary Patency Through 12 months Post-AVF Creation [12 months post-procedure]

    Freedom from access thrombosis from time of access creation

  3. Secondary Procedures Rate [12 months post-procedure]

    Number of surgical or percutaneous interventions designed to mature or maintain the AVF or re-establish flow per person-year.

  4. Overall Patient Safety [12 months post-procedure]

    A full characterization of adverse events during the study

Inclusion Criteria:
  1. Male or non-pregnant female ≥ 18 years of age and ≤ 80 years of age

  2. Life expectancy of at least one year, in the investigator's opinion

  3. Diagnosed with ESRD or chronic kidney disease on hemodialysis.

  4. Patients deemed medically eligible for upper extremity autogenous AV fistula creation, per institutional guidelines and/or clinical judgment

  5. Adequate quality vein based on pre-operative assessment

  6. Adjacent vein diameter of ≥2.0 mm at target anastomosis site

  7. Confirmed clinically significant outflow

  8. Adequate quality radial artery based on pre-operative assessment

  1. Arterial lumen diameter of ≥2.0 mm at target anastomosis site
  1. Adequate collateral arterial perfusion with patent palmar arch as demonstrated by Barbeau Test.

  2. Radial artery-adjacent vein proximity ≤1.5 mm measured lumen edge-to-lumen edge as determined by pre-procedural ultrasound and confirmed pre-procedure

  3. Patient is able to provide written informed consent and attend follow-up examinations at the enrolling institution

Imaging-based Inclusion Criteria:
  1. Confirm radial artery-adjacent vein proximity ≤1.5 mm measured lumen edge-to-lumen edge as determined by pre-procedural ultrasound and confirmed pre-procedurally

  2. Confirm radial artery and adjacent vein diameter of ≥2.0 mm at target anastomosis site

Exclusion Criteria:
  1. Pre-existing ipsilateral vascular disease interfering with the study procedure or potentially confounding the study results including:

  2. Documented or suspected central venous stenosis (≥ 50%) or

  3. Upper extremity arterial stenosis or

  4. Vascular disease at the radial artery / adjacent vein site

  5. Prior vascular surgery at or proximal (central) to the AVF target site interfering with AVF maturation or other ipsilateral surgery that could potentially confound the study results such as prior axillary dissection or mastectomy

  6. History of steal syndrome from a previous surgical ipsilateral hemodialysis vascular access which required intervention or abandonment

  7. Systolic pressures < 100 mg Hg at the time of screening

  8. Suspected or confirmed skin disease at the skin entry site

  9. Edema of the upper extremity on the ipsilateral side

  10. Immunocompromised subjects due to underlying disease or immunosuppressant therapy such as sirolimus (Rapamune®) or Prednisone at a dose of > 10 mg per day

  11. Known bleeding diathesis, coagulation disorder or medications putting the subject at increased risk, in the Investigator's judgment

  12. Patients with acute or active infection

  13. Scheduled kidney transplant within 6 months of enrollment

  14. Participation in another clinical investigation (excluding retrospective studies or studies not requiring a consent form)

  15. History of substance abuse or anticipated to be non-compliant with medical care or study requirements based on investigator judgment

  16. Patient has an active COVID-19 infection or relevant history of COVID-19 (Relevant history of COVID-19 is defined as availability of a positive COVID-19 test with sequela or hospitalization for treatment of COVID-19. Patients with a positive COVID-19 test who were asymptomatic or had mild symptoms may be included if the positive test was more than 6 months prior to enrollment.)
