1.Flexible Tip Flexible tip is designed to deflectwhen in contact of the dura or blood vessel.preventing blood vessel puncture and otherinadvertent penetration.

2.Coil-reinforced Coil-reinforcement providesa balance of strength and softness. While easyto thread, it is not too rigid to cause inadvertentdamage to soft tissue and cause paresthesia.

3.Polyurethane Made of Polyurethane withhigh bio-compatibility and reliability; suitablefor long period of administration and reduces paresthesia.

4.Radio-opaque Radio-opaque, ensuring preciseplacement.

5.Kink and stretch resistance Kink andstretch resistant to better ensure patency underdifferent patient postures.3 separate observation windows to monitorblood backflow or spinal fluid leak.

6.3 separate observation windows to monitorblood backflow or spinal fluid leak.

7.Centimeter graduations from 5 to 20 cm fromthe distal tip.

8.Black mark at the distal tip to shows the catheterhas been fully removed from the patient.
