Primary Outcome Measures:
  • Technical Success [ Time Frame: Within 24 hours of the Index procedure ] [ Designated as safety issue: No ]

    The first primary endpoint is primary technical success. It consists of the following items:

    • Successful arterial access
    • Successful deployment of the Endograft with secure proximal and distal fixation
    • Absence of type I or III endoleaks
    • Patent Endograft without significant twist, kinking, or obstruction

  • Major Adverse Events (MAE) [ Time Frame: Within 1-Month of Implantation ] [ Designated as safety issue: No ]

    The second primary endpoint is associated with the safety profile of the device, and is defined as the percent of patients experiencing one or more of major adverse events (MAE) within one month of implantation. MAE are defined as any one of the following events:

    • Death
    • Myocardial Infarction
    • Stroke (excludes TIA)
    • Renal failure (excludes renal insufficiency)
    • Respiratory Failure (excludes COPD or pulmonary complications)
    • Paralysis (excludes paraparesis)

Secondary Outcome Measures:
  • Clinical Success and Safety of the Aptus Endograft and EndoStaple components [ Time Frame: 1-Month, 6-Months and 12-Months ] [ Designated as safety issue: No ]

    Clinical Success is defined as Successful Deployment of the Endograft at the intended location and the absence of:

    • Death as a result of aneurysm-related treatment
    • Type I or III endoleak
    • Endograft infection
    • Endograft thrombosis
    • Endograft dilatation by 20% or more in diameter
    • Endograft migration by 10mm or more at the proximal neck at 6-M and 12-M
    • Loss of Endograft or EndoStaple integrity
    • Aneurysm expansion by 5mm (or more) in maximal diameter at 6-M and 12-M
    • Aneurysm rupture
    • Conversion to open repair

Estimated Enrollment: 100
Study Start Date: August 2010
Estimated Study Completion Date: August 2013
Estimated Primary Completion Date: August 2012 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions

Detailed Description:

The Aptus Endosystems STAPLE International Post-Market Registry is intended to expand the clinical knowledge base by including 'real world' subjects.

All subjects diagnosed with a qualifying AAA suitable for elective endovascular repair, who meet the inclusion/exclusion criteria for the registry, are eligible for enrollment and should be offered informed consent to participate.


Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population

Subjects diagnosed with a qualifying AAA suitable for elective endovascular repair.


Inclusion Criteria:

  1. Patient ≥ 18 years old
  2. Patient has given written informed consent
  3. Patient has a life expectancy > 1 year
  4. Patient is willing to comply with follow-up evaluations
  5. Patient's AAA meets at least one of the following criteria:

    • ≥ 4.5cm in diameter
    • Increased in size by 0.5cm in last 6 months
    • Maximum diameter exceeds 1.5 times the transverse dimension of an adjacent normal aortic segment
    • Saccular aneurysm larger than 3cm in maximal diameter
  6. Patient has a proximal aortic neck diameter measured inner wall to inner wall between 19mm and 29mm
  7. Patient has a proximal aortic neck length of at least 12mm
  8. Patient has a patent iliac or femoral artery that allows endovascular access to the aneurysmal site with 16Fr (5.3mm) or 18Fr (6.0mm) delivery system.
  9. Patient has bilateral iliac artery distal fixation site ≥ 10mm in length with an internal diameter between 9mm and 20mm

Exclusion Criteria:

  1. Patient is participating in a concurrent clinical study which may confound STAPLE-International Registry results
  2. Patient has a symptomatic AAA
  3. Patient's AAA has a proximal aortic neck angle that is > 60 degrees between the infrarenal neck and the long axis of the aneurysm
  4. Patient has irregularly-shaped plaque that would inhibit sealing stent apposition
  5. Patient has aortic mural pathology that is ≥ 2mm in thickness over ≥ 50% of the circumference of the proximal fixation site
  6. Patient has an active, or known history of, bleeding diathesis or hypercoagulable condition
  7. Patient has a contraindication to any materials to which he or she will be exposed during the EVAR procedure (i.e., Endograft or EndoStaple materials, contrast agents)
  8. Patient has a genetic connective tissue disorder (e.g., Marfan's or Ehlers-Danloe Syndromes)
