Designed to transplant more organs

and improve outcomes

OrganOx metra is transforming liver transplantation, enabling functional assessment of donor organs prior to transplantation, reducing early allograft dysfunction and improving transplantation logistics, to the benefit of both transplant recipients and hospitals.1—4

metra for liver transplantation

With the OrganOx metra, the donor liver is continuously perfused with oxygenated blood, medications and nutrients at normal body temperature and near physiological pressures and flows. The metra is fully automated, easy-to-use and can preserve the donor organ in a functional state for up to 24 hours.1, †
