Soft Shell Mushroom Artificial Heart

The Soft Shell Mushroom Total Artificial Heart has an actively opening and closing mushroom-shaped inflow valve. An air sac around the stem of the mushroom when inflated expels the blood from the ventricle during systole. A hard septum is held partly over the left ventricle. Dacron netting is attached to it to constrain the ventricle during systole. The heart was made by Willim Kolff's sons Alfred and Cornelis (Case), and implanted by Dr. Clifford Kwan-Gett in the summer of 1968 at the University of Utah.
