Dual Channel Vascular Access Harness for Mice

The Instech Dual Channel Vascular Access Harness (VAH) permits quick and aseptic connection and disconnection of a catheterized mouse and an infusion tether.

• Septum permits aseptic technique
• Quick connection
• Minimal backflow
• Low profile
• Single channel options also available

The VAH consists of a small external port (or two ports, in the case of the dual channel model) housed in a harness which is installed at the same time that the catheter is implanted. The catheter is attached to a connector built into the port under the harness dome. The port and catheter are filled with lock solution to maintain patency during transport.

To begin an infusion or blood sampling study, simply remove the cap, wipe the septum with disinfectant and plug the mating VAH tether into the harness. A recessed septum-piercing needle built into the tether makes the fluid connection through the port. Like a subcutaneous access port, the VAH is a closed system; tether connection does not introduce contamination or air. Furthermore, retrograde flow, which can lead to occluded catheters, is virtually eliminated.

All products are supplied individually sterilized, unless otherwise noted.
