1. TIP : Anti-suction maximize flow even when the catheter is against vessel wall. 2. Luminal Design : Low profile comparing to others in the market which allow highest blood flow , strengthened septum which resist kinking 3. Low profile polyster cuff for catheter anchoring. 4. Hub : Crack resistant hub material 5. Fully biocompatible carbothane material conforms to vessel anatomy resulting in higher patient tolerance during extended use. 6. Extension tubes ; Crack resistant material that withstand repeated longterm use.
