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 (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
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 or for custom
configurations.
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.
