This transcutaneous button features an external port with a septum for quick, clean and repeated access to a rat's implanted catheter. Applications include bolus or continuous dosing, blood sampling and IV self-administration. For intermittent access use a syringe fitted with a needlefree PinPort™ injector; for continuous access from outside the cage snap in a mating tether.
The design, updated in 2017, uses magnets for low stress connection, and smaller PinPorts™ so that tethers, injectors and caps are compatible with the two-channel buttons.
Group house animals by using the protective aluminum cap — an animal welfare benefit that has never before been available to rats with externalized catheters.
NOTE: These buttons are not MRI-compatible due to the magnets. We do have an MRI-compatible button: VAB95BS-MRI, with a twist-in connection and a Nitinol connector.
This two minute video demonstrates the use of the Vascular Access Button™ from surgery to blood sampling, infusion, and group housing.
