On February 4, 1966, a permanent type of auxiliary ventricle was implanted into a patient by Dr. Adrian Kantrowitz.
Although that patient only lived one day, Dr. Kantrowitz implanted another device in a 63-year-old woman on May 22, at Maimonides Hospital in Brooklyn, New York. The woman died of a cerebral stroke 13 days later.
