Brief Summary:
The purpose of this study is to compare endovascular repair using any FDA approved Medtronic AAA Stent Graft System versus surveillance in subjects with smaller abdominal aortic aneurysms (AAA)(4-5CM), with respect to AAA rupture and AAA related deaths.

Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Positive Impact of Endovascular Options for Treating Aneurysms Early (PIVOTAL)

Arm Intervention/treatment
No Intervention: Surveillance
Experimental: Early Endovascular Repair Device: AneuRx AAA stent graft / Talent AAA stent graft
Catheter based stent graft inserted to seal off an abdominal aortic aneurysm

Primary Outcome Measures :
  1. Number of Subjects That Experienced Rupture or Aneurysm Related Death [ Time Frame: 3 years ]

Secondary Outcome Measures :
  1. Aneurysm Growth >0.5 cm [ Time Frame: 1 year ]
    After repair, AAA enlargement by >0.5cm

  2. Secondary Endovascular Procedures Between the 30-day Post Treatment and 3-year Follow-up [ Time Frame: study termination ]
    secondary interventions in those that had successful delivery and deployment by treatment group randomized to.
