Working knowledge: Left ventricular assist devices: Restoring flow
Article Abstract:
Left ventricular assist devices (LVADs) are used to keep heart failure patients alive until they get an available transplant organ. The complications involved in LVAD devices are discussed and engineers are evaluating experimental, third-generation devices, which use magnetically levitated rotors, reducing moving parts.
