Outcome Measures

Primary Outcomes (2)

  • Safety: Major Adverse Events (MAE)

    The primary safety endpoint is defined as the incidence of Major Adverse Events (MAE) at 30 days, defined as the composite of the following All-Cause Mortality; Bowel Ischemia; Myocardial Infarction; Paraplegia; Renal Failure; Respiratory Failure; Stroke; Procedural Blood Loss ≥1,000cc

    30 days

  • Effectiveness: Rate of Treatment Success

    The primary effectiveness endpoint is defined as the rate of Treatment Success at year 2. Treatment Success is a composite of outcomes clinically relevant to the endovascular repair of infrarenal AAA as follows: It is defined as procedural technical success and absence of Abdominal aortic aneurysm rupture; Conversion to open surgical repair; Endoleak Type I or III at year 2; Clinically significant migration; \> 5mm aneurysm sac enlargement of the maximal diameter as measured by the difference from the 30-Day CT time point; or Secondary endovascular procedure up to year 2 for resolution of Endoleak (Type I or Type III), Device obstruction or occlusion, Device migration, Abdominal aneurysm sac expansion, Device defect.

  • Patient agrees to all follow-up visits;
  • Abdominal aortic aneurysm with sac diameter ≥5.0cm, or ≥4.5cm which has increased by ≥0.5cm within the last 6 months, or or which exceeds 1.5 times the transverse dimension of an adjacent non-aneurysmal aortic segment. No AAA \<4 cm will be included.
  • Anatomically eligible for the Nellix System (per Instructions For Use):
  • Adequate iliac/femoral access compatible with the required delivery systems (diameter ≥6 mm);

  • Most caudal renal artery to each hypogastric artery length ≥100mm;
  • Common iliac artery lumen diameter between 9 and 35mm;
  • Distal iliac artery seal zone with length of ≥10mm and diameter range of 9 to 25mm;
  • Ability to preserve at least one hypogastric artery.
  • Ratio of maximum aortic aneurysm diameter to maximum aortic blood lumen diameter \<1.40

You may not qualify if:

  • A patient who meets none of the following criteria potentially may be included in the study:
  • Life expectancy \<2 years as judged by the Investigator;
  • Psychiatric or other condition that may interfere with the study;
  • Participating in another clinical study;
  • Known allergy or contraindication to any device material;
  • Coagulopathy or uncontrolled bleeding disorder;
  • Ruptured, leaking or mycotic aneurysm;
  • Serum creatinine (S-Cr) level \>2.0 mg/dL;
  • CVA or MI within three months of enrollment/treatment;
  • Aneurysmal disease of the descending thoracic aorta;
  • Clinically significant mural thrombus within the proximal landing zone (minimum 10mm) of the infrarenal non-aneurysmal neck (\>5mm thickness over \>50% circumference);
  • Connective tissue diseases (e.g., Marfan Syndrome);
  • Unsuitable vascular anatomy that may interfere with device introduction or deployment;
  • Pregnant (female of childbearing potential only).

Model Details: Prospective, multicenter, single arm study with consecutive, eligible subject enrollment at each site. All subjects will undergo the Endovascular Aneurysm repair procedure with the Nellix System. Sites have been chosen with a suitable research infrastructure and physician experience in endovascular aneurysm repair to ensure adequate enrollment. Subjects will be followed procedurally to discharge, at 30 days (primary safety endpoint), six months, one year (primary effectiveness endpoint) and annually thereafter to five years (total follow-up commitment).
