Abstract
The present invention relates to a perfusion loop assembly for an ex vivo liver perfusion including: a pump for providing a fluid flow of a perfusion fluid through a first branch line and a second branch line; the first branch line being configured to provide a first portion of the perfusion fluid to the hepatic artery of the liver; the first branch line being coupled with a first gas exchanger, the second branch line being configured to provide a second portion of the perfusion fluid to the portal vein of the liver; the second branch line further including a first valve for controlling the flow of the perfusion fluid into the portal vein of the liver, a liver chamber assembly configured to hold the liver ex vivo, a liver outlet line attached to the vena cava of the ex vivo liver, at least one reservoir connected to the liver outlet and upstream from the pump.
