Vascular Access Button™

This implantable button features an external port with a septum similar to the Vascular Access Harness™ for quick, aseptic connection and disconnection of a catheterized rat and an infusion tether. They are ideal for long-term studies with protocols that call for intermittent tethering, such as IV self administration or blood sampling. The button was developed in collaboration with Janssen Pharmaceuticals in Belgium.[1]

Compared to the DC95BS, which uses a Dacron® mesh, the VAB95BS buttons feature a sturdier medical-grade polyester felt. Attach a 3Fr polyurethane catheter (included with part number VAB95BS-C) to a 22ga connector under the felt. The button is implanted at the time of catheterization; to begin an infusion study simply disinfect the septum and plug in the mating VAB95T tether. The recessed septum-piercing needle will make the fluid connection without exposing the fluid path to the environment.

An optional aluminum protective cap is available to permit group housing when animals are not tethered. Please contact Instech for pricing on order quantities of 50 or more pieces or for custom configurations.
