PRIMARY outcome

Timeframe: 30 days +/- 7 days

Primary safety endpoint * Access site-related bleeding requiring transfusion; * Vascular injury requiring repair (via surgery, ultrasound guided compression, transcatheter embolization or stent graft); * New ipsilateral lower extremity ischemia causing a threat to the viability of the limb and requiring surgical or additional percutaneous intervention. This compromised blood flow is documented by subject symptoms, physical exam and/or a decreased or absent blood flow on lower extremity angiogram.; * Access site-related infection requiring intravenous antibiotics and/or extended hospitalization; * New onset access site-related neuropathy in the ipsilateral lower extremity requiring surgical repair; * Permanent access site-related nerve injury.
