Multipurpose central venous access using the cordis sheath introducer system.

A nonpyrogenic polyethylene sheath system with a hemostatic valve assembly and side port extension developed by the Cordis Corporation is now routinely used for central venous access in critically ill patients. It is inserted percutaneously via the subclavian or internal jugular vein and allows rapid and efficient catheterization for hemodynamic monitoring, infusion of multiple solutions simultaneously, and uniflow hemodialysis. This system represents a significant advance in catheter technology.
