Rat Portal Vein (tip blunt level for blood sampling, data the same as S25A)

Description

This IITC Life Science catheter is designed for chronic implantation into the portal vein of rats, featuring a blunt-level tip configuration optimized for blood sampling. As indicated, its performance data is equivalent to the manufacturer's S25A model. The device enables direct access to the hepatic portal circulation, allowing researchers to collect blood samples that reflect the composition of blood draining from the gastrointestinal tract before it is processed by the liver. Using a chronically implanted catheter for this purpose permits sampling in conscious animals, thereby avoiding the acute hemodynamic and metabolic changes induced by anesthesia and surgical stress. This tool is critical for studies investigating hepatic metabolism, nutrient absorption, gut-derived hormones, and the first-pass effect of pharmaceuticals.
