Metra

Conventional cold preservation involves storage of the liver at 4˚C, using a non-physiological perfusion solution that aims to minimise liver degradation. By contrast, warm preservation seeks to re-create an environment that mimics the human body by continuously perfusing at physiological pressures and flows with oxygen-carrying red cells at 37˚C and providing nutrition. The liver is therefore functional during the preservation period, producing bile, metabolizing glucose and maintaining a physiological pH. This enables objective assessment of organ performance prior to transplant, extended preservation times.

The metra device has a rugged, robust design for ease of transport and safe storage when not in use.  It has an extended battery life for transportation and a self regulating oxygen supply, removing the need to carry gas canisters. 

The metra has a simple control panel, and the sterile disposable circuit is pre assembled, making it simple and rapid to prime, as well as being easy to dispose of after the procedure.

Ease of use is paramount, and the fully automated perfusion of metra maintains physiological temperature, flows, pressures, oxygenation and records bile production, all of which are displayed on the built in graphical user interface.  

All connectors are simple and rapid to use, ensuring that preparation time is minimal.
