1. Stable chemical properties, good biocompatibility and good
hydrophilicity;
2. The tube body is soft and elastic, reducing the damage to the
inner wall of blood vessels and preventing the tube body from being
distorted;
3. Smooth inner and outer wall of the tube, protect the inner wall
of the blood vessel, effectively prevent thrombosis, and reduce the
resistance of catheterization;
4. No scale tube body, indicating the need to put all the tube body
into the body;
5. The whole tube body can be developed under X-ray to facilitate
positioning;
6. Oval cavity design increases the flow rate of the tube body, and
it is easy to recanalize the tube with guide wire after
embolization.
