RADIAL ACCESS FOR VISCERAL INTERVENTION (R.A.V.I.)

Embolization is a highly effective way of controlling bleeding and is much less invasive than open surgery. When using Transradial Artery Access (TRA) in embolization procedures, proven benefits are obtained such as reduced bleeding complications, easy access site management, improved patient satisfaction and the opportunity for same day discharge. 1-8

TREAT MORE PATIENTS

  • Easier access site management
  • Reach visceral anatomy and beyond with longer access products
  • Patient-preferred

INCREASE EFFICIENCIES

  • Allows for same-day-discharge
  • Reduce costs and improve procedure time
  • Ease of access to vessel origins from above

REDUCE PROCEDURAL COMPLICATIONS

  • Less bleeding complications at the access site
  • Low risk for stroke
  • No reliance on internal closure device
