Studies with a slit-valve catheter for parenteral nutrition.
A new catheter for central venous total parenteral nutrition has a blunt occluded distal end and a longitudinally oriented slit one centimeter proximal. Studies in rats show that this slit-valve prevents both reflux of blood and intracatheter thrombosis. This may be a factor in reducing sepsis associated with central venous total parenteral nutrition.
