But now, doctors in Toronto are trying to increase the number of possible kidney donors with a new device they hope can fix the blood compatibility problem.
George Alvarez is a kidney patient who has already used the device. When his kidney failed and he needed a new one, his wife, Maria Moya, offered hers right away. But because Maria has blood type B and George has type O, doctors knew that the antibodies in George's blood would eventually attack the donated kidney and the organ would fail.
