Temporary Occlusion and Aspiration System

GuardWire Temporary Occlusion and Aspiration System

The GuardWire® Temporary Occlusion and Aspiration System is a simple and elegant solution to distal protection.

How the GuardWire System Works

The GuardWire Temporary Occlusion and Aspiration System has demonstrated a reduction in cumulative MACE events following saphenous vein graft interventions. Easy to use, GuardWire Temporary Occlusion and Aspiration System features the EZ Adaptor device, which works seamlessly with the EZ Flator® inflation device.

When compared to unprotected procedures, the SAFER1 Trial showed:

  • 42% reduction in MACE
  • 41.5% relative reduction in myocardial infarction
  • 56.6% relative reduction in mortality
GuardWire procedure sequence


  • Occlusion and Aspiration System
    • Atraumatic compliant balloon
    • Aspiration of debris
  • Ultra-low profile minimizes the risk of dislodging embolic debris
    • Combination of Nitinol and proprietary helical design enables distal maneuverability and flexibility
    • 2.7F crossing profile for sizes 3.0-6.0mm
    • 2.1F crossing profile for sizes 2.5-5.0mm
  • Compact 11mm balloon length
    • Shorter length enables distal flexibility
  • 2.5cm shapeable and radiopaque wire tip
