Clinical Evidence for Angio-Seal Vascular Closure Devices

More than 700 published clinical manuscripts establish the following benefits of our Angio-Seal vascular closure devices:

  • Improved patient comfort1
  • Decreased nursing time, improved turnaround time and better throughput in cath labs2,3
  • Opportunity for same-day discharge4
  • Lowered complication rates following percutaneous coronary interventions (PCIs) and diagnostic  procedures, including:
    • Groin hematoma5
    • Groin bleeding5
    • Femoral pseudoaneurysm5
    • Lower limb ischemia / arterial stenosis5


A recent analysis of bleeding-avoidance strategies for patients undergoing PCIs involved the use of various vascular closure devices, including Angio-Seal™ vascular closure devices. The results suggest that determining a bleeding-management strategy for high-risk patients may improve the safety and cost-effectiveness of PCIs.6 The study reported that vascular closure devices were associated with a 23 percent reduction in bleeding rates—a significant reduction compared to manual compression.6

Failed closure is a leading predictor of vascular complications.7 Angio-Seal vascular closure devices demonstrate high success rates and low complication rates:8

  • 99.7 percent deployment success8
  • 97.8 percent hemostasis by device8
  • Multiple studies confirm its safety profile7,8

The  Angio-Seal Vascular Closure Device product family, including the STS Plus, VIP and Evolution platforms, is indicated for use in closing and reducing time to hemostasis of the femoral arterial puncture site in patients who have undergone diagnostic angiography procedures or interventional procedures using an 8 French or smaller procedural sheath for the 8 F Angio-Seal device and a 6 French or smaller procedural sheath for the 6 F Angio-Seal device. The Angio-Seal STS Plus, VIP and Evolution platform devices are also indicated for use to allow patients who have undergone diagnostic angiography to safely ambulate as soon as possible after sheath removal and device placement, as well as to allow patients who have undergone an interventional procedure to safely ambulate after sheath removal and device placement.

Important Safety Information:
Possible adverse events for vascular closure devices include, but are not limited to: bleeding or hematoma, AV fistula or pseudoaneurysm, infection, allergic reaction, foreign body reaction, inflammation or edema. This device should only be used by a licensed physician (or other health care professional authorized by or under the direction of such physician) possessing adequate instruction in the use of the device, e.g., participation in an Angio-Seal physician instruction program or equivalent.
