Vascular Access Harness™ for Mice

Instech’s new mouse VAH™, an advancement on the Covance Infusion Harness™, permits quick, aseptic connection and disconnection of a catheterized mouse and an infusion tether.

Like its larger cousin for rats, the system consists of two parts: a miniature external port housed in a harness (VAH62AB) and a mating spring tether with a connector (VAH62T) that pierces the septum to make the fluid connection. Mice can be ordered with a catheter and the harness pre-installed (see Partners list at left). Then, to begin an infusion study, simply wipe the septum with disinfectant and connect the VAH tether to the harness. Flush, inject into or sample from the harness directly as needed using a syringe fitted with an VAHLS25/30 injector. Do not use other types of needles to access the the very small septum in the mouse VAH; they can damage the septum or fail to make a connection.

The standard system is designed for single channel infusion for blood sampling of mice using a 25ga swivel. For best results use our specially designed 2Fr polyurethane catheter with a rounded tip and a molded hub that fits the 22ga connector in the harness. A 4cm version of this catheter is included with part number VAH62AB-JVC for jugular vein catheterization.

All parts are supplied EtO sterilized. Please contact Instech for pricing on order quantities of 50 or more pieces or for custom configurations.
