![]() They act as a “sheath” around these other catheters, providing a clean path and protected portal for these catheters to enter a vessel, whilst allowing simultaneous administration of fluid via the side-port or side-catheter, which runs perpendicular to the sheath, and has standard luer-lock connections to which IV giving sets can be connected. Sheath introducers are long, very wide bore, single lumen catheters with a wide plastic hub on the proximal end, which has a central smaller hole (one-way-valved to prevent back-flow of blood), through which various other vascular catheters can be inserted, including triple-lumen central lines, Swann-Ganz catheters (hence the name “Swann sheath”), temporary external pacing wires and coronary angiography catheters.
