The Future of Organ Transplantion

By keeping the donor heart warm and functioning, the OCS™ is designed to enable your doctor to continuously monitor the hearts’ function during transport and ensure its suitability for transplantation. The technology is designed to allow surgeons to preserve more hearts and transport them from a greater distance.
