  • Description

Vascular Access Harnesses with infusion port

Instech’s 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. Animals 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 or inject directly into the harness as needed using a syringe fitted with a VAH6M injector with needle stick protection. Use the SIP22P plug to seal off the tether connector while the animal is not connected.

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).
