This product is a single-lumen braided catheter of graduated stiffness, with a large non-conical cavity which facilitates the interventional or diagnostic devices to pass through the blood vessel.The Catheter is coated with a hydrophilic coating at its outer surface which reduces the friction with the Catheter during endovascular operation. Its inner cavity is lined with self-lubricating polytetrafluoroethylene, which facilitates the movement of devices such as guidewire.

The distal end of the Catheter is developing under the ray and its head end has an obvious developing ring. All these are beneficial to improve the developing effect. The head end of the Catheter is pre-shaped to fit in place. The dismountable guiding sheath tube is an attached accessory to guide the Catheter into the puncture sheath.
