Kantrowitz-Avco Mechanical Auxiliary
On February 4, 1966, a
permanent type of auxiliary ventricle was
implanted into a patient by Dr. Adrian
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.
The Kantrowitz-Avco "booster
heart" that was implanted inside the
patient'sbody. Only the air tube and the
electrodes extend through the chest wall.
Dr. Kantrowitz positions his device in a
The Kantrowitz-Avco device reduces the
work ofthe left ventricle by drawing in blood as
the heart contracts. Then, as the heart relaxes,
a signal from the heart itself triggers an
external control which sends a burst of air into
the unit, forcing the blood along its way.
