Bench performance supports CFVAD miniaturization; hypothesis-generating pending in vivo validation before clinical consideration.
A prototype continuous flow ventricular assist device with magnetic bearings demonstrated adequate flow and pressure generation with acceptable hemolysis in a simulated circulation system, supporting further miniaturization.
Allaire et al. (1996) studied this question. Prototype continuous flow pump (CFVAD2) fully supported in magnetic bearings was evaluated on Pump performance (flow, pressure head, hemolysis). The prototype continuous flow pump (CFVAD2) supported in magnetic bearings delivered 6 L/min of flow at 100 mm Hg operating at 2,400 rpm in water without indicating damage to blood cells.
