A perfusion loop assembly for ex vivo liver perfusion includes a pump providing perfusion fluid through a line branching at a branching point into a first branch line and a second branch line. The first branch line provides a first portion of the perfusion fluid to the hepatic artery of the liver, the first branch line coupled with a gas exchanger, where the first branch line includes a flow rate sensor and/or a pressure sensor. The second branch line provides a second portion of the perfusion fluid to the portal vein of the liver; the second branch line includes a valve for controlling flow of perfusion fluid into the portal vein. The second branch line includes a flow rate sensor and/or a pressure sensor. A liver chamber assembly holds the liver ex vivo, and an outlet line for the perfusion fluid connects the liver chamber assembly and the pump.

Perfusion loop assembly for an ex-vivo liver perfusion and a method for ex-vivo liver perfusion

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.
