Polyurethane Or Silicone Hemodialysis Catheter

A hemodialysis catheter is a specialized medical device used to provide vascular access for patients undergoing hemodialysis, particularly in acute or chronic kidney failure. Made from biocompatible materials such as polyurethane or silicone, the catheter is designed for temporary or semi-permanent insertion into a central vein, commonly the internal jugular, subclavian, or femoral vein. It features dual lumens—one for drawing blood out of the body and the other for returning it after filtration—ensuring efficient, high-flow dialysis treatment. The catheter is equipped with a radiopaque tip for precise placement under imaging guidance and often includes suture wings or cuffs to secure its position and reduce infection risk. Sterile, single-use packaging and smooth internal surfaces minimize clot formation and ensure optimal performance. Hemodialysis catheters are vital for managing renal failure, offering immediate access with minimal trauma while maintaining strict standards of patient safety and comfort
