The system integrates a compact wireless monitor, an organ specific perfusion module, and proprietary solutions for organ maintenance, the manufacturer explains, adding: ‘Hearts beat, lungs breathe, kidneys produce urine, livers produce bile.’ |In transit, a donor heart, for example, can be connected to the pulsatile pumping system and perfused with warm, oxygenated donor blood and nutrients, thus reducing time dependent ischemic injury.
This not only lengthens the transportation time, potentially expanding the catchment area of a transplant centre, but also enables fully functional, biochemical and metabolic assessment of the organ by the receiving physician and potentially enabling the transplant surgeon time to resuscitate the organ ex vivo to build up its energy stores, optimise its function and perform full viability assessment prior to transplantation.
The OCS may also enable the utilisation of organs currently not used due to the limitation of the existing preservation method.
The device was first used for a beating heart transplant in February 2006 in Bad Oeynhausen, Germany -- where it became available at selected heart centres in 2007.
Meanwhile, the OCS has received CE approval and the series recently expanded to include the OCS Lung transportation device.
In view of discussions regarding the amendment of the organ donor law, this May members of the German parliamentary committee on healthcare, led by Dr Carola Reimann and supported by Professor Martin Strüber of the Medical University Hannover, Germany, visited TransMedics in Andover, Massachusetts, for a first-hand presentation of the Organ Care System.
