​Flow redistribution

Occlusafe allows you to redistribute the flow in such way that therapeutics agents are preferentially accumulated in the targeted lesion.


Accurate navigability allows for segmental and sub-segmental catheter positioning with Terumo hydrophilic coating.

No reflux

  • Atraumatic procedures
  • High quality occlusive balloon
  • No reflux: Complete occlusion prevents back-flow and non-target embolization3
  • Arterial flow beyond the catheter tip was maintained even after balloon inflation4
