Stylets, Vascular, Vein, Vena Cava

Definition : Stylets designed to ease insertion of a cannulae into the vena cava. These stylets typically are metallic wires or flexible rods that provide a rigid or semi-rigid structure; usually the stylets are withdrawn after the cannula is introduced through the femoral vein and advanced into the vena cava so only the hollow catheter remains in the vein. Dedicated vena cava stylets are used in particular procedures (e.g., cardiopulmonary bypass) and/or to transfer intravenous solutions into the vena cava; some stylets are customized for patients with abnormal superior vena cava.
