  Purpose
The objective of this trial is to demonstrate the safety and effectiveness of the Cardiva VASCADE™ Vascular Closure System (VCS) in sealing femoral arterial access sites. Hypothesis: The Cardiva VASCADE™ VCS provides times to hemostasis (TTH) and time to ambulation (TTA) results that are less than manual compression by a clinically meaningful and statistically significant margin. The rate of major access site-related complications with the Cardiva VASCADE™ VCS is non-inferior to the major complication rates of manual compression for sealing femoral arterial access sites.

Condition Intervention

Primary Purpose: Treatment
Official Title: A Multi-Center, Prospective, Randomized, Controlled, Trial to Evaluate the Safety and Efficacy of the Cardiva VASCADE™ Vascular Closure System (VCS) vs. Manual Compression for the Management of the Femoral Arteriotomy After Percutaneous Endovascular Procedures

Primary Outcome Measures:
  • Time to Hemostasis (TTH) [ Time Frame: Up to 1 hour ]
    Primary effectiveness endpoint - elapsed time between device (VASCADE) or sheath (manual compression) removal and first observed and confirmed arterial hemostasis.

  • Rate of Combined Access Site-related Major Complications [ Time Frame: 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. (> 30 days)


Secondary Outcome Measures:
  • Time to Ambulation (TTA) [ Time Frame: Up to 1 day ]
    Secondary effectiveness endpoint - elapsed time between device (VASCADE) or sheath (manual compression) removal and when subject stands and walks 20 feet without evidence of arterial re-bleeding

  • Time to Discharge Eligibility (TTDE) [ Time Frame: Up to 2 days ]
    Secondary effectiveness endpoint - elapsed time between device (VASCADE) or sheath (manual compression) removal and when subject is medically able to be discharged based solely on the assessment of the access site, as determined by the medical team

  • Time to Hospital Discharge (TTHD) [ Time Frame: Up to 2 days ]
    Secondary effectiveness endpoint - elapsed time between device (VASCADE) or sheath (manual compression) removal and when subject is actually discharged from the hospital

  • Device Success [ Time Frame: Up to 1 day ]
    Secondary effectiveness endpoint - ability to deploy the delivery system, deliver the collagen, and achieve hemostasis with VASCADE alone or with adjunctive compression

  • Procedure Success [ Time Frame: 30 days +/- 7 days ]
    Secondary effectiveness endpoint - attainment of final hemostasis using any method and freedom from major vascular complications through 30 days

  • Rate of Combined Minor Access Site Complications [ Time Frame: 30 days +/- 7 days ]

    Secondary safety endpoint

    • Access site-related bleeding requiring greater than 30 minutes to achieve hemostasis;
    • Access site-related hematoma > 6 cm;
    • Late access site-related bleeding (following hospital discharge);
    • Ipsilateral lower extremity arterial emboli;
    • Ipsilateral deep vein thrombosis;
    • Access site-related vessel laceration;
    • Access site wound dehiscence;
    • Localized access site infection treated with intramuscular or oral antibiotics;
    • Arteriovenous fistula not requiring treatment;
    • Pseudoaneurysm requiring thrombin injection or fibrin adhesive injection;
    • Pseudoaneurysm not requiring treatment;
    • New onset access site-related neuropathy in the ipsilateral lower extremity not requiring surgical repair;
    • Ipsilateral pedal pulse diminished by two grades or transiently lost.
