To evaluate how well the new system, called OrganEx, works, the researchers caused heart attacks in pigs that had been anesthetized. The pigs were dead for an hour, and the researchers cooled their bodies and used neural inhibitors to ensure the animals did not regain consciousness during subsequent experiments.

Then, the researchers began to use the OrganEx system. They compared its performance against ECMO, a life-support technology used in hospitals today in which a machine oxygenates blood and circulates it throughout the body.

OrganEx restored circulation and prompted the repair of damaged cells. For example, the scientists saw heart cells contract and electrical activity return. Other organs, including kidneys, also showed improvements, the study says.
