Two channel Vascular Access Harness ™ for rats

This implantable button for rats connects two independent fluid channels simply by engaging the mating tether. It is the same size as the one-channel rat Vascular Access Button™. Connect two 3Fr catheters to the 22ga inputs under the felt disk. The small PinPorts™, one red and one white, can be accessed manually using a syringe fitted with a PNP3M injector. The mating tether snaps into the button with magnets to minimize the force on the animal. The magnets are oriented so that the tether can only be connected one way: the white port connects to the tubing with the white stripe. For two continuous lines connect a 25ga dual channel swivel; alternatively, connect one line to a single channel swivel for continuous access and then allow the second line to rotate freely with a PinPort™ for intermittent dosing or sampling.
