What Is A Contrast Catheter?

Contrast catheter is the key equipment for percutaneous angiography. It should have appropriate hardness, elasticity, flexibility and torsion; it should have good X-ray opacity; its shape memory should be good; Performance should be kept to a minimum. The contrast catheter is a long plastic tube, and its main function is to provide a guide so that the contrast agent can be smoothly introduced into the blood vessel to produce a contrast effect. Therefore, a contrast catheter should meet the following basic conditions: the inner tube is smooth and can generate high flow rate; the imaging performance is high; the non-traumatic tip must have a very high original shape retention performance and is not easy to deform; the guide wire can be easily passed through, etc.
