Supports compact fully implantable LVAD designs; leaves open clinical translation beyond animal models.
Does incorporating electronics within the HeartMate III blood pump allow for a compact design without excessive temperature rise in preclinical models?
Incorporating electronics into the HeartMate III LVAD is feasible with minimal size increase and acceptable thermal performance in preclinical testing, advancing the development of fully implantable systems.
Bourque et al. (2002) studied Left ventricular assist device indication. HeartMate III blood pump with incorporated motor drive and levitation control electronics vs. Pumps without incorporated electronics was evaluated on Operational problems and temperature rise. Incorporation of electronics within the HeartMate III blood pump resulted in no operational problems over 5 months in vitro and only a 1°C temperature rise during a 20-day in vivo test.
