The aim of this randomized study is to compare the safety and performance of EndoVascular Aneurysm Repair with ESAR using Endurant + Heli-FX™ EndoAnchor™ system and FEVAR using customizable grafts from Cook (Zenith Fenestrated Graft) and Terumo (Fenestrated Anaconda Graft) for the treatment of aortic aneurysms with short aortic neck (4 to 15mm).


Full study title Physician Initiated Trial Investigating ESAR (EVAR plus Heli-FX EndoAnchors) and FEVAR for the Treatment of Aortic Aneurysms with Short Infrarenal Aortic Neck.
Protocol number OCR44303 ID NCT04503395
Phase N/A


Inclusion Criteria:

  • Subject is >18 years old

  • Subject is scheduled for primary treatment of the abdominal aortic aneurysm with a non-aneurysmal infrarenal aortic sealing zone proximal to the aneurysm that is sufficiently healthy for a proximal neck length that is at least 4mm and not more than15 mm and has a circumferential minimum sealing zone length of 8 mm

  • Subject is not a candidate for safe and effective standard EVAR

  • Subject is able and willing to comply with the protocol and to adhere to the follow-up requirements.

  • Subject has provided written informed consent

  • Subject meets the other anatomical requirements according to the locally applicable Endurant II/IIs stent graft system, Heli-FX EndoAnchor system, Terumo Fenestrated Anaconda (available in EU only) and/or Cook Zenith Fenestrated Graft Instructions for Use

  • Proximal neck length of the aorta within 4-15mm and a minimum circumferential sealing zone of 8mm

  • Aortic neck diameter from 19 to 31mm

  • Infrarenal neck angulation ≤45°

Exclusion Criteria:

  • Subject is participating in a concurrent study which may confound study results

  • Subject has a life expectancy 50%

  • Subject has active infection or history of COVID-19. History of COVID-19 is defined as availability of positive COVID-19 test with sequelae or hospitalization for treatment of COVID-19.

Participate in a study

Here are some general steps to consider when participating in a research study:

  1. Step

    Contact the research team

    Call or email the research team listed within the specific clinical trial or study to let them know that you're interested. A member of the research team, such as the researcher or study coordinator, will be available to tell you more about the study and to answer any questions or concerns you may have.

    Primary contact

  2. Step

    Get screened to confirm eligibility

    You may be asked to take part in prescreening to make sure you are eligible for a study. The prescreening process ensures it is safe for you to participate. During the prescreening process, you will be asked some questions and you may also be asked to schedule tests or procedures to confirm your eligibility.

  3. Step

    Provide your consent to participate

    If you are eligible and want to join the clinical trial or study, a member of the research team will ask for your consent to participate. To give consent, you will be asked to read and sign a consent form for the study. This consent form explains the study's purpose, procedures, risks, benefits and provides other important information, such as the study team's contact information.

  4. Step


    If you decide to participate in a clinical trial or study, the research team will keep you informed of the study requirements and what you will need to do to throughout the study. For some trials or studies, your health care provider may work with the research team to ensure there are no conflicts with other medications or treatments.
