2. Fig 1
Two centrifugal blood pumps are implanted in the abdominal wall, directly under the diaphragm. The pump shown on the left is the right ventricular assist device (RVAD), and the pump shown on the right side is the left ventricular assist device (LVAD). (TETS = transcutaneous energy transmission system.)
