Vascular Access Harnesses™

Simple, Proven Tethering for Rats

The Vascular Access Harness (VAH™) system consists of a small external port housed in a harness which can be installed at the same time that the catheter is implanted. For best results use Instech 3Fr polyurethane catheters.

Access the harness manually to sample, dose or check patency using a syringe with a VAH6M injector. For continuous infusion or sampling connect a mating tether.

The VAH is a closed system: tether connection does not introduce contamination or air.

Harness bands should be checked regularly for appropriate fit. Rats cannot be group housed with harnesses.

Our mouse harnesses (not listed here) remain available, but based on customer feedback we recommend Vascular Access Buttons for mice instead.
