This implantable single-channel button features an external port with a septum for quick, aseptic connection and disconnection of a catheterized rat and an infusion tether.
Attach a 3Fr polyurethane catheter (for example: JVCs, FVCs, CACs) 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 connect the mating VAB95T tether with a twist. The recessed septum-piercing needle will make the fluid connection without exposing the fluid path to the environment. Alternatively, access the button manually with the needle-free VAH6M injector. Use the VAB95CAP protective cap to group house animals when they are not tethered.
Differences between this original model and the newer VABR1B/22 buttons include:
