Insufficient thrust precludes human use; leaves open viability of linear motor artificial hearts pending >10% design gains.
The linear pulse motor-driven artificial heart LAH-S91 requires a >10% increase in thrust to sustain human life, with a maximum permissible loss of 42 W.
Yamaguchi et al. (1993) studied this question. Linear pulse motor-driven artificial heart (LAH-S91) was evaluated on Performance characteristics (thrust and maximum permissible loss). Performance testing of the LAH-S91 artificial heart revealed insufficient thrust to sustain human life (requiring >10% increase) and a maximum permissible loss of 42 W for a 1°C temperature rise.
