What are some commonly used precision medical catheters?
2025-03-31
1. Central Venous Catheter
Central venous catheters are generally made of medical-grade polyurethane, exhibiting excellent biocompatibility. The catheter is clearly visible under X-rays and is equipped with a specially designed flexible soft tip to minimize vascular damage.
(2) Dialysis Catheter
A dialysis catheter is a catheter specifically designed for hemodialysis, providing a safe and effective conduit for connecting the central venous catheter to the dialysis machine. Dialysis catheters are mostly made of medical-grade polyurethane, possessing high elasticity and excellent biocompatibility. The scientifically designed lumen ensures the catheter has good rigidity and low fluid resistance; various models such as straight-tip, extended-tip, and curved catheters are available.
(3) Arterial Sheath
The arterial sheath primarily provides a safe and effective channel for inserting catheters into the body.
(4) Rapid Exchange PTCA Balloon Catheter
The rapid exchange PTCA balloon catheter is used for treating coronary artery stenosis. It provides state-of-the-art interventional devices for coronary heart disease interventions.
The tubing connecting the catheter and the balloon is made of a special new type of material, with moderate softness and hardness, allowing it to flexibly adapt to the curvature of the blood vessels for smooth insertion. The catheter uses a dual-lumen design, with the outer lumen used for balloon inflation and the inner lumen for guiding wires to reach and pass through the narrowed blood vessels that need expansion.
(5) Intravascular Stent
Intravascular stents are used in the treatment of mitral stenosis, myocardial infarction, and conditions caused by stones or tumors.
