Figure 2a : The Jarvik-7 artificial heart. Design of the Jarvik-7 incorporates two heart pumps and a power console (Fig. 2c). Both heart pumps are small enough to fill the void left behind during ventricle extraction. The pumps (Fig. 2b) receive power through a large external console that pushes air through percutaneous tubing. Inside the pumps, entering air forces a series of thin flexible diaphragms to expel blood through the pumps. Seven feet away from the patient rests a heavy power console (Fig. 2c) from which doctors adjust the patient's heart rate and the cardiac output. Figure 2b : Schematic of the Jarvik-7 blood pump. Air enters the driveline from the consoleand pushes on the diaphragm layers. The diaphrgm layers expand to propel blood through the aortic valve. Figure 2c : The drive console of the Jarvik-7. Patients with the Jarvik-7 were tethered to this device by seven feet of air tubing which connect directly to the heart pumps by passing through the skin. The drive console weighs nearly 300 pounds.
