  • Central venous infusion catheters designed for insertion in the peripheral vasculature (typically in the basilic or cephalic veins) and that are long enough to advance and locate their distal tip in a central vein, usually the superior or inferior vena cava. The length of these catheters is typically 22 to 60 cm (9 to 24 inches), and they are usually made of silicone elastomers (silastic) or polyurethane. They may be inserted using a variety of techniques (e.g., using a breakaway needle introducer, though over-the-needle catheters are provided with guide wires using the Seldinger technique); most of these catheters are provided with guide wires to assist their insertion.
