One channel Vascular Access Harness™ for rats

The Vascular Access Harness™, an advancement on the Covance Infusion Harness™, permits quick, aseptic connection and disconnection of a catheterized rat and an infusion tether. The system consists of two parts: a miniature external port housed in a harness (VAH95AB) and a mating spring tether with a connector (VAH95T) that pierces the septum to make the fluid connection. Flush or inject directly into the harness as needed using a syringe fitted with a VAH6M injector. Then, to begin an infusion study, wipe the septum with disinfectant and connect the VAH tether to the harness. The standard system is designed for single channel infusion of rats using a 22ga swivel. For best results use 3Fr polyurethane catheters with inner diameters of 0.024-0.025in (0.60-0.64mm).
