Jugular Vein Catheter (PE20 170mm, PE10 65mm, Silastic 0.025" OD 37mm)

Description

This product is a jugular vein catheter assembly designed for chronic implantation in laboratory rats. It is intended for use in conscious, freely moving animals to facilitate intravenous drug administration or sampling without the need for restraint or repeated needle insertions. The catheter assembly from IITC Life Science is constructed from multiple materials: a section of PE20 tubing measuring 170 mm in length, a section of PE10 tubing measuring 65 mm in length, and a segment of Silastic tubing with a 0.025-inch outer diameter and a length of 37 mm. This multi-material design is typical for chronic implants, where different sections serve specific functions related to flexibility, biocompatibility, and connection to external ports. The use of chronically implanted catheters allows researchers to administer substances or draw blood samples while minimizing confounding variables such as stress from handling, the acute effects of surgery, or the influence of anesthesia. This enables more physiologically relevant pharmacological, pharmacokinetic, and behavioral studies. The technique supports various administration routes, including intravenous delivery into the general circulation or the portal vein, as well as subcutaneous or intraperitoneal injection for non-irritating compounds.
