From the Vygon catalogue, double-lumen PUR catheters (e.g., Nutriline Twinflo / Multicath) are designed for central venous access, especially in neonates and paediatric patients. These catheters allow simultaneous infusion of different solutions through separate lumens, improving treatment efficiency. Made from radiopaque polyurethane, they offer excellent visibility and optimal balance between rigidity and flexibility for easier insertion. The catheter includes centimetre markings for accurate placement and is typically used with a split introducer system. It reduces repeated venous punctures, preserving vessel integrity. Supplied sterile, it is widely used in ICU settings for safe and reliable vascular access.
