What is Full MagLev?
Uses magnets to support all six degrees of freedom of the rotor, such that the rotor remains essentially fixed except for rotation.
(Doesn’t use physical or hydrodynamic/blood bearings)

HeartMate III*: Full MagLev™ Technology
Key Design Features: Large and Consistent Gaps (Designed to minimize Shear Stress and Blood Component Activation)
– HeartMate III secondary flow paths are ~0.5 mm along the side, and ~1.0 mm pump above and below the rotor.– Conversely, hydrodynamic bearings are typically operated with much smaller gaps, 0.05 of
a millimeter or so.– HeartMate III pump surfaces are flat and flow is undisturbed; wedging surfaces and other
features required for hydrodynamic bearings are not required.~ 0.5 mm
along the side
~ 1.0 mm top and bottom

HeartMate III*: Full MagLev TechnologyKey Design Feature: Pulsatility (Minimize stasis)• These large gaps also enable the rapid speed
changes used by our artificial pulse feature without rotor/housing contact.
• Some potential benefits:• Designed to promote washing of the pump
• Prevents the formation of zones of recirculation and stasis.
• Zero Net Change in Flow• Speed ramps up and down (zero net change)
• Potential Clinical Benefits1-3
• For example, a theorized source of bleeding in chronic support with constant-speed rotary pumps involves the development of arteriovenous malformations, a syndrome associated with persistently low pulse pressure
