Abstract

Ventricular assist devices (VAD) augments the heart's ability to supply blood at necessary volume flow rates and pressures. Mechanical optimization was performed using the finite element analysis package PAM-CRASH on the VAD. The ejection fraction of the pump increased with increasing cylindricity and was influenced by the maximum circumferential curvature. An optimal value of emax existed for each pump size. The number of collapse points in the sac varied from two to six with three providing the best sac performance.
