About this study

Official title: Ellipsys Vascular Access System Registry, Protocol 1.0. Version 1.0

Ellipsys Vascular Access System Registry will enroll up to 100 patients to evaluate the use and performance of the Ellipsys Vascular Access System when it is used within its intended use in accordance with standard of care in a clinical setting. The Ellipsys Vascular Access System is intended for use to create an arteriovenous (AV) fistula via percutaneous access.

Read the detailed description

Ellipsys Vascular Access System Registry is a non-randomized, prospective, post-market, multi-center registry of the Ellipsys Vascular Access System in which up to 100 patients will be enrolled to evaluate the use and performance of the Ellipsys Vascular Access System when it is used within its intended use in accordance with standard of care in a clinical setting. The Ellipsys Vascular Access System is intended for use to create an AV fistula via percutaneous access. The primary performance endpoint is Clinical Success at the 90-day endpoint, where Clinical Success is defined as an access site that achieves a venous diameter of greater than or equal to 4 mm and blood flow greater than or equal to 500 ml/min in the brachial artery as measured via duplex ultrasound.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Ellipsys Vascular AccessDevice

    The Ellipsys Vascular Access System comprises the Ellipsys Catheter, Ellipsys Crossing Needle and Ellipsys Power Controller. The Ellipsys Crossing Needle is used to facilitate access between the artery and the vein. The Ellipsys Catheter is placed percutaneously into the selected vein in close proximity to the selected artery. The Ellipsys Catheter is actuated at the selected anastomosis site, and the vein and artery are approximated. Once the vessels are in the appropriate relative positions the catheter is connected to the Ellipsys Power Controller to create the anastomosis after which the Ellipsys Catheter is removed, and the access site is closed using standard percutaneous closure techniques.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The number of patients with a vascular access site that achieves a venous diameter of greater than or equal to 4 mm and blood flow greater than or equal to 500 ml/min in the brachial artery as measured via duplex ultrasound.

    Primary endpoint

    Measured: 90 days

Secondary outcomes (6)
  1. Percent of Ellipsys Vascular Access procedures that successfully create an arteriovenous fistula (AVF) excluding Access Failures.

    Device Success Rate

    Measured: 12 months

  2. The length of time until a patient is able to undergo 2-needle cannulation for dialysis OR access vessel has a diameter ≥ 6 mm and a mean flow rate of ≥ 600 ml/min if the patient is not undergoing dialysis.

    Time to Functional Patency

    Measured: 12 months

  3. Percent of patients that require dialysis and sustain 3 consecutive 2-needle cannulations at the prescribed needle gauge and blood flow rate.

    Dialysis Rate

    Measured: 12 months

  4. The number of surgical or endovascular interventions required to achieve or maintain Functional Patency.

    Secondary Procedure Rate

    Measured: 12 months

  5. Number of patients with patency defined as an anastomosis that has flow whether it is being used for dialysis or not.

    Arterio-venous fistula patency

    Measured: 12 months

  6. Length of time from initial access creation to achieve Functional Patency or to time of abandonment of AVF.

    Cumulative patency

    Measured: 12 months

Questions about this trial

What is this clinical trial studying?

An observational study of End-stage Renal Disease, run by Medtronic Endovascular at 5 sites in Germany.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 11 inclusion and 12 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 8 Feb 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 5 sites in Germany. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The number of patients with a vascular access site that achieves a venous diameter of greater than or equal to 4 mm and blood flow greater than or equal to 500 ml/min in the brachial artery as measured via duplex ultrasound. (time frame: 90 days). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Feb 2021.
