This implantable single-channel button features an external port with a septum for quick, aseptic connection and disconnection of a catheterized rat and a tether for continuous access, or needlefree intermittent access with a syringe.
The button contains no metal, making it MRI-compatible: the catheter connector is 22ga Nitinol, not stainless steel, and the tether connects with a twist-in connection similar to a luer fitting, rather than with magnets as in our standard VABR1B/22 buttons.
Attach a 3Fr polyurethane catheter (for example: JVCs, FVCs, CACs) to a 22ga connector under the felt. 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.
NOTE: The original version of this button, VAB95BS, has been discontinued and replaced by VABR1B/22.
