1. Nitinol + stainless steel cores provide superior flexibility and durability, improves the torque response.
2. 3cm Platinum coil at distal tip provides excellent radiopacity.
3. A hydrophilic coating is applied to the 30cm coiled distal end to increase the crossability and deliverability.
4. PTFE coating on middle and proximal parts reduces friction, and improves pushability and catheter trackability.
