Vascular Access Harness™
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. 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 an SN22
septum needle or the male VAHLS22/30
connector with needlestick
protection.
The system is designed for single channel infusion of rats
using a 22ga swivel. For best results use the 3Fr polyurethane
catheters; a 20cm rounded-tip PU catheter specifically designed for
the VAH is available as part of part number VAH95AB-C. All parts are
supplied EtO sterilized.
Please contact Instech for
pricing on order quantities of 50 or more pieces, for custom
configurations, or for a list of animal vendors that offer VAH and catheter
installation as a surgical service.
Now also available in a two-channel version.

Ordering tips: if you already have swivels, order VAH95AB +
VAH95T. If you need swivels with each tether, order VAH95AB
+ KVAH95T. Order the lower dead volume VAH95T/ABS when using
with the Instech Automated
Blood Sampler.
